Question: 1 / 400

What are heterotrophs?

Organisms that can produce their own food

Organisms that obtain energy by consuming other organisms

Heterotrophs are defined as organisms that cannot produce their own food and instead obtain their energy by consuming other organisms. This includes a wide variety of life forms, such as animals, fungi, and many bacteria, which rely on different sources for nutrition, including plants, other animals, or organic matter.

Understanding this definition helps clarify the role of heterotrophs in the ecosystem, as they are essential for energy transfer within food chains and webs. By consuming autotrophs (organisms that can produce their own food, such as plants) or other heterotrophs, these organisms play a vital part in maintaining ecological balance and supporting energy flow through different trophic levels.
