Question

How do matter and energy move through an ecosystem? Your answer should include at least 6 complete sentences to explain the claim, evidence and reasoning.

Answer 1

Producers make all the food that is present in an ecosystem or food web. This means that we can trace all the energy and matter in a food web back to the primary producers. ... Producers create their own food, consumers use other organisms as a source of food, and decomposers break down dead plants and animals.

Answer 2

One example:

Energy moves through an ecosystem through different organisms. For example, plants can absorb energy from the sun. Animals, such as grasshoppers, can eat the plants and the energy goes to them. Progressing higher up the food chain, the energy continues to transfer through different animals - grasshoppers can be eaten by mice, mice by snakes, snakes by eagles, etc. etc.
