Questions and Answers

What is the main difference between autotrophs and heterotrophs?

Autotrophs can make their own food, while heterotrophs rely on other organisms for food. (correct)

Heterotrophs can produce their own food, while autotrophs rely on other organisms for food.

Autotrophs only eat plant matter, whereas heterotrophs eat other animals.

Autotrophs are always carnivores, while heterotrophs can be herbivores or omnivores.

Why are autotrophs referred to as producers?

Because they can convert sunlight into energy efficiently.

Because they have the ability to reproduce rapidly in the ecosystem.

Because they rely on a variety of food sources for their survival.

Because they produce their own food using photosynthesis or chemosynthesis. (correct)

What role do decomposers play in the ecosystem?

Decomposers help recycle dead organisms back into the soil and release important nutrients. (correct)

Decomposers are consumers that primarily feed on living plants and animals.
