Evan is learning about energy transfer within an ecosystem. He is given the provided diagram. The diagram shows how energy from the sun moves through a simple food chain, including the energy transferred between organisms and the energy lost to heat. Evan concludes that which of the following, regarding the diagram, supports the law of conservation of energy?

A. A The total amount of energy decreases within the system.
B. B The total amount of matter remains the same within the system.
C. C The total amount of energy remains the same within the system.
D. D The total amount of energy increases within the system.

C

Explanation: Most of the energy is lost as heat, the rest is used as energy for the animals. But the energy is still in the ecosystem just not in a form that is usable. So, the energy all ways remains the same. Energy can't be destroyed or created only transformed into a new form.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
