Study guides

8

5 Biogeochemical Cycles

Explore how water and essential elements move between organisms, the atmosphere, water, soil, and rocks, and how human activities can change those cycles.
Study guide · Updated

6 Biodiversity and Conservation

Learn how biodiversity is organized and measured, why it matters, what threatens it, and how conservation can protect and restore life on Earth.
Study guide · Updated

8 Environmental Change and Ecological Interactions

Follow how environmental changes affect organisms, populations, communities, and ecosystem processes, and learn to assess ecological impacts using cause-and-effect evidence.
Study guide · Updated

7 Evolution and Ecology

Explore how evolution changes populations over generations, how ecological conditions shape that change, and how evolving species influence their communities.
Study guide · Updated

1 Foundations of Ecology
