Give your biology students a focused look at quantifying energy flow 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 "In a typical ecosystem, what percentage of energy is usually lost between trophic levels?", "In energy pyramids, what does the base represent?", and "What is the primary source of energy for most ecosystems?"
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 Defining Carrying Capacity, Factors Affecting Population, Biodiversity Within Ecosystems, Population Interactions, Matter Cycling in Ecosystems, and Energy Transfer Pathways, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 10 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-LS2-4.
