Food Chains

Link: Food Chains

Like "Food Web," this NRICH activity focuses on the connections between plants and animals in an ecosystem. However, it's also slightly more challenging than "Food Web." Students are forced to calculate the number of animals in a population and then consider how different events might impact the cycle.

Their calculations will have them using operations (likely forcing them to think about ratios and percents, Grade 6 content). In terms of science, this activity will help students meet 5-LS2-1: "Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment" specifically focusing on LS2.A: "Interdependent relationships in ecosystems."
