The answer is C To eat producers and produce energy
Answer:
C. To eat producers and produce energy.
Explanation:
In a food chain, a series of organisms are linked to together in a process whereby one eats the other and provides energy at each trophic level.
Every food chain typically starts with the producers who obtain the energy either through the sun or chemicals and make their own food,
The organisms who eat the producers are known as primary consumers and they are the ones who provide energy to the next trophic level of the secondary consumers .
The food chain is as follows:
Producer (plant) ---> primary consumer (herbivore)---> secondary consumer (carnivore)- --> tertiary consumer

Which best describes the relationship between temperature and dissolved oxygen in a lake?
A.
As temperature increases, dissolved oxygen increases.
B.
As temperature increases, dissolved oxygen decreases.
C.
As temperature decreases, dissolved oxygen decreases.
D.
A change in temperature has no effect on dissolved oxygen.
Answer:
B
Explanation:
Gases slightly dissolve in water and are held loosely by weak inter-molecular forces. When the water gains temperatures, the kinetic energy of the water molecules including those of the gases increase. The dissolved gas molecules are therefore able to overcome the weak forces of attraction in the water and escape through the surface.
Dissolved oxygen levels in a lake usually decrease as the temperature increases. Warmer waters hold less oxygen than cooler waters. For instance, a decrease in dissolved oxygen could happen when lake water heats up during the summer.
Explanation:In a lake ecosystem, there is a relationship between the temperature and levels of dissolved oxygen. Generally, the amount of dissolved oxygen in water decreases as the temperature increases. So, the correct answer would be 'B. As temperature increases, dissolved oxygen decreases.' Warmer waters hold less dissolved oxygen than cooler waters. This occurs because gas solubility is a function of temperature: The warmer the temperature, the less gas there will be dissolved, including oxygen.
For example, when the lake water gets heated up during the summer, dissolved oxygen levels may decrease.

Explain how a snail's body plan and anatomy enables invertebrate to perform the essential functions it needs to survive.
To analyze the external anatomy of snails, we will divide their body into the shell and the soft body that holds it. The former is a solid spiral-shaped structure carried on the back, made of a single piece and consisting mostly of calcium carbonate. The central layer of the shell, called ostracism, has two layers of crystals of the same substance, calcium carbonate. The Hipostracum is below, and the most superficial layer is the periostracum, composed of a lot of proteins.
The shell of a land snail can be very different in size and shape depending on the species. Some of them are cone-shaped while others are round. However, all of them have a spiral design, caused by the way land snails produce and growth their shells.
This structure protects the snail from the environment and even from predators. It is made up of calcium carbonate which makes it strong and remains that way as long as the snail consumes food with calcium.
Its surface can show different colors with fringe designs, but they usually are brown or yellow. The shell protects the body and internal organs of the animal and has an opening to one side, usually the right.
The body plan and anatomy of a snail play key roles in its survival. The shell affords protection and moisture retention, a muscular foot allows for movement and burrowing, and specialized systems enable digestion, respiration, circulation, and navigation in its environment.
Explanation:A snail's body plan and anatomy contributes to its survival in several ways, thereby performing essential functions. Most notably, the shell of the snail serves as a protective barrier, preventing predation and aiding in moisture retention, crucial for survival in a variety of habitats. The snail's muscular foot allows for locomotion and burrowing into substrate, for hiding or seeking food. The radula, a unique anatomical structure, enables the snail to scrape food particles off surfaces and into its mouth.
Additionally, snails possess a complex respiratory system adapted to their environment. Terrestrial snails, for instance, have a lung-like structure while aquatic ones have gills. Invertebrates like snails also have a simple circulatory system where the heart pumps blood directly to the body cavities without the need for a complex network of blood vessels like in vertebrates. Finally, the nervous system of snails, though simpler than vertebrates, is sufficient for the detection of light, touch, chemicals, balance, and even some can sense gravity which helps them in their interaction with the environment.

which would BEST allow a species to survive environment changes
The answer you are looking for is genetic diversity
To survive environmental changes, a species' best strategies include having high genetic diversity, the capability for sexual reproduction, and phenotypic plasticity. Proactive conservation efforts are essential to prevent extinction, especially in climate-sensitive species.
The best strategy for a species to survive environmental changes involves high genetic diversity, the ability to reproduce sexually in case of asexually reproducing species, and phenotypic plasticity. Genetic diversity enhances a species' ability to adapt to new conditions, and sexual reproduction can introduce new gene combinations that may offer better survival strategies during rapid environmental shifts. Furthermore, phenotypic plasticity, the ability of an organism to change its phenotype in response to environmental changes, plays a crucial role in survival. For example, the crystalline iceplant adjusts its water needs based on environmental availability, which has allowed it to thrive in diverse environments globally.
Conservation strategies must be proactive, allowing species to adapt at their own pace to prevent extinction due to climate sensitivity. This may include ensuring unfragmented habitats to enable species to shift their ranges in response to climate change, as fragmented habitats can prevent migration to suitable areas, leading to potential extinction.

How many trophic levels are there in the following food web
Answer: A.4
Explanation:
The food web provided in the image, there are C.3 trophic levels. Therefore ,C.3 is correct .
Producer: Grass is the producer at the base of the food web, as it can produce its own food through photosynthesis.
Primary Consumer: Worms are the primary consumers, as they consume the producers (grass) directly.
Secondary Consumer: Spiders are the secondary consumers, as they consume the primary consumers (worms).
The robin is not part of the food web as it does not directly feed on the worms.
Trophic levels are the different feeding positions in a food chain or web. They are numbered starting with the producers at the bottom, then the primary consumers, then the secondary consumers, and so on.
The energy in the food web flows from the producers to the primary consumers to the secondary consumers.
At each level, some of the energy is lost as heat, so there is less energy available at each higher trophic level. This is why there are typically no more than four trophic levels in a food web.

What process or event was required for plate tectonics to begin on earth ?
Older oceanic crust, which is more dense than continental crust, has long since been recycled in the process of subduction. Credit: U.S. Geological Survey. Plate tectonics shapes the surface of our planet, but it also runs much deeper: Plate movement is the surface expression of convection in Earth's interior.
Answer:
The tectonic plates appeared when the earth began to cool, where the water flooded the earth. The earth that was submerged originated the tectonic plates.
Explanation:
Plate tectonics are large semirigid rock blocks that make up the earth's crust. The Earth is divided into fourteen main tectonic plates, which move slowly and continuously over the mantle, and can approach or move away from each other. The movement of the plates results in the formation of mountains, oceanic pits, volcanic activities, earthquakes and tsunamis.
The formation of tectonic plates was a result of the cooling and flooding of the earth. When the earth began to cool, where water flooded the earth. The submerged earth originated the tectonic plates.
describe two properties of an exchange surface that would facilitate rapid diffusion rates
molecules and gaseous
The diffusion rate across an exchange surface is dictated by the extent of the concentration gradient and the surface area and thickness of the plasma membrane. A higher concentration gradient and larger surface area promote rapid diffusion, whilst a thicker plasma membrane slows down diffusion.
Explanation:Two properties of an exchange surface that would facilitate rapid diffusion rates are the extent of the concentration gradient and the surface area and thickness of the plasma membrane.
The extent of the concentration gradient is a key determinant of the diffusion rate. The greater the difference in concentration between two regions, the faster diffusion occurs. On the other hand, when the distribution of the material approaches equilibrium, the diffusion rate tends to decrease.
The surface area and thickness of the plasma membrane also affect the rate of diffusion. A larger surface area enables more materials to diffuse simultaneously across the membrane, thereby increasing the diffusion rate. Conversely, a thicker membrane inhibits the passage of materials, leading to a slower diffusion rate. This principle is applied in cells, where surface area-to-volume ratios are used to predict which cell(s) might eliminate wastes or procure nutrients faster by diffusion.

C. Plant roots absorb the water that would otherwise wash away the soil.
D. Plant roots take up space, leaving very little soil present to erode.
Quite sure it's not B or D and sources online are either saying it's A or C.
Answer:
Underground, plant roots look like a tangled web. roots hold soil in place and prevent water from washing it away.
the answer is A
Plant roots help prevent soil erosion by holding the soil and stabilizing it against the erosion flow. Thus, the correct option is A.
How do plants prevent soil erosion?Plants are very effective in reducing soil erosion by keeping the soil clumped together. This happens even when water is flowing over the soil or through it.
Plant roots also help the soil to regain its structure by allowing the exchange of nutrients and minerals.
The microbiota associated symbiotically with plant roots also help in maintaining the integrity of the soil. They add a strengthening texture to the soil.
Plant roots increase the amount of force needed to uproot the plant, as it is the root mainly involved in stabilizing the plant in the soil.
It has also been found that the fine hairs present on the roots also reduce soil loss by either holding the soil in place or by releasing materials that help reinforce soil.
