In a food chain, what is the role of a producer?

Producers convert light energy into chemical energy through photosynthesis, providing energy for the rest of the food chain.

Explain the difference between a primary consumer and a secondary consumer.

Primary consumers eat producers, while secondary consumers eat primary consumers.

Tertiary consumers are at the top of the food chain. They eat secondary or primary consumers.

Sun → Grass (Producer) → Grasshopper (Primary Consumer) → Mouse (Secondary Consumer) → Hawk (Tertiary Consumer)

I can describe how energy flows through a food chain.

1
A food chain is a model that shows how energy flows between living things in an ecosystem.
2
Producers, like plants and phytoplankton, transform the sun's energy into chemical energy through photosynthesis.
3
In a food chain, primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers eat secondary or primary consumers.
