Give your biology students a focused look at competition for resources with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Sample questions include "Which of the following would likely occur if a predator is removed from an ecosystem?", "What does the term 'niche' refer to in ecology?", and "What would likely happen if two species occupy the same niche?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a standards aligned biology unit. The unit also covers Resources and Population Size, Types of Species Interactions, Interactions Across Ecosystems, Matter Cycling in Ecosystems, Energy Flow in Food Webs, and Ecosystem Changes, 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-LS2-1.
