Autotrophs and Heterotrophs

Front

What are autotrophs?

Back

Autotrophs are organisms that can make their own food using sunlight or chemical energy.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot make their own food and must obtain energy by consuming other organisms.

Front

Give an example of an autotroph.

Back

Plants are a common example of autotrophs, as they use photosynthesis to create their own food.

Front

Give an example of a heterotroph.

Back

Animals, including humans, are examples of heterotrophs because they eat plants or other animals for energy.

Front

What is a carnivore?

Back

A carnivore is an animal that gets energy by eating other animals.

Front

What is a herbivore?

Back

A herbivore is an animal that gets energy by eating only plants.

Front

What is an omnivore?

Back

An omnivore is an animal that gets energy by eating both plants and animals.

Front

How do autotrophs contribute to the ecosystem?

Back

Autotrophs produce oxygen and organic materials that serve as food for heterotrophs, forming the base of the food chain.

Front

What role do heterotrophs play in the ecosystem?

Back

Heterotrophs help in the transfer of energy through the food chain by consuming autotrophs and other heterotrophs.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which autotrophs, like plants, convert sunlight into chemical energy to make food.
