What is a decomposer?

Back

Decomposers are organisms that break down dead or decaying organisms, returning nutrients to the soil.

Front

What is the role of sunlight in an ecosystem?

Back

Sunlight is essential for photosynthesis, allowing producers to create energy-rich compounds.

Front

What happens to energy as it moves up the food chain?

Back

Energy decreases as it moves up the food chain due to energy loss at each trophic level.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.

Front

What is the top predator in a food chain?
