Difference between a food chain and a food web

Back

A food chain shows a single pathway of energy flow, while a food web shows multiple pathways.

Front

Plants contribute to energy flow in an ecosystem by capturing sunlight and converting it into chemical energy through photosynthesis, providing energy for animals.

Back

Energy flow in ecosystems is initiated by plants through photosynthesis.

Front

A consumer in an ecosystem is an organism that cannot make its own food and must eat other organisms for energy.

Back

Consumers rely on other organisms for their energy needs.

Front
