BIOLOGY: 4. ECOLOGY AND THE ENVIRONMENT

This topic examines the interactions between various organisms and their environments. Students will learn how energy flows through ecosystems, how populations interact, and how key nutrients are recycled. The impact of human activity on ecosystems – including pollution, deforestation, and climate change – is also explored, helping students understand both natural processes and environmental responsibility.

We're releasing our Biology study bundles gradually, so you'll only see links for subtopics that are currently available. As soon as a bundle is complete, the link will go live and be available for purchase.
