Give your biology students a focused look at ecosystem changes with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Students will answer questions such as "What impact does urban development have on local wildlife?", "How does pollution impact aquatic ecosystems?", and "What can occur when a keystone species is removed from an ecosystem?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a standards aligned biology unit. The unit also covers Resources and Population Size, Competition for Resources, Types of Species Interactions, Interactions Across Ecosystems, Matter Cycling in Ecosystems, and Energy Flow in Food Webs, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-LS2-4.
