The food chain, food web, and energy pyramid are all models that show feeding relationships and allow us to make predictions. Compare and contrast the strengths and weaknesses of each model by filling in the table below.
Select four cards to create a food chain, starting with a producer. Label the trophic level of each organism in your food chain as follows: producer, primary consumer, secondary consumer, tertiary consumer. Record your food chain in the space below using species names and arrows.

In this worksheet, we will practice interpreting the interdependent relationships of organisms in ecosystems using food webs. Q1: Each link of the food chain is named according to what the organism eats and how it contributes to the energy of the ecosystem.
4. Draw a food web which illustrates a feeding relationship between at least ten organisms. Include the four organisms in the food chain you drew in (1). [10] 5. Choose one organism in the food web you drew in (4) and draw a circle around this organism. Imagine that this organism was eliminated (removed) completely from the feeding relationship.
A food web shows how energy is passed on from one living thing to the next. It shows the feeding habits of different animals that live together in an ecosystem. In the food web pictured on the left, energy is passed from the grass to the mouse to the snake to the hawk.
