Topics Explored: Aquatic Biomes, Carbon Cycle, Nitrogen Cycle, Phosphorus Cycle, Hydrologic Cycle, Solar Energy, Trophic Levels, Keystone Species, Food Chains and Food Webs

This case study examines largemouth bass function as a keystone species in freshwater ecosystems of North America. Students will investigate food chains, food webs, and ecosystem dynamics while uncovering how solar energy and biogeochemical cycles sustain life beneath the water’s surface. As largemouth bass are a keystone species within their aquatic biome, this case study is a keystone activity for APES Unit 1.   Answer key included.

    Case Study:Largemouth Bass

    Excellent resource for teaching ecology in honors biology, and a useful review of fundamental concepts for my APES course. It includes everything needed to reinforce concepts covered at the beginning of the year that could appear on the exam..

    Thank you so much for the kind review! We’re glad to hear the Largemouth Bass case study worked well for both Honors Biology and APES. One of our goals is to create resources that reinforce fundamental concepts in a meaningful and engaging way while still helping students prepare for the AP exam. We truly appreciate your support!
