What type of organism is at the top of the food chain and what is their role?

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

Draw a simple food chain with at least four organisms, including a producer, primary consumer, secondary consumer, and tertiary consumer. Label each organism with its role in the food chain.

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

Energy Flow in Food Chains

7th Grade•50 minutes•NGSS MS-LS2-3

Learning Objective

I can describe how energy flows through a food chain.

Key Concepts

A food chain is a model that shows how energy flows between living things in an ecosystem.

Producers, like plants and phytoplankton, transform the sun's energy into chemical energy through photosynthesis.

In a food chain, primary consumers eat producers, secondary consumers eat primary consumers, and tertiary consumers eat secondary or primary consumers.
