What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.

Front

What are consumers?

Back

The energy in a food chain starts from the Sun, which is captured by producers.

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

Back

As energy moves up the food chain, it decreases because some energy is lost as heat and through metabolic processes.
