What is the role of producers in an ecosystem?

Back

Producers, like plants, convert energy from the Sun into food through photosynthesis.

Front

How do consumers obtain energy?

Back

Consumers obtain energy by eating other organisms, including plants and animals.

Primary consumers eat producers (plants), while secondary consumers eat primary consumers.

Front

What are decomposers?

Back

Decomposers are organisms, like fungi and bacteria, that break down dead organic matter and recycle nutrients back into the ecosystem.

Front

How does energy flow in an ecosystem?

Back

Energy flows from producers to consumers and then to decomposers.

Front

What is the significance of the Sun in an ecosystem?

Back

The Sun is the primary source of energy for most ecosystems, providing the energy needed for photosynthesis.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy from one level to the next.

Front

What is the relationship between algae and crustaceans in an aquatic food web?

Back

Energy is transferred from algae (producers) to crustaceans (consumers) in an aquatic food web.

Front

Why can't animals make their own food?

Back

Animals lack the ability to perform photosynthesis and must obtain energy by consuming other organisms.
