Ecology and ecosystems

Understand ecosystems, energy transfer, nutrient cycling, succession and human impacts on biodiversity

What you'll learn

  1. 1

    Imagine a pond in your garden — it has water plants, tiny bugs, fish, and frogs all living together. That's an ecosystem!

  2. 2

    Which of these is part of an ecosystem? 🏞️

  3. 3

    Drag each living thing into the pond to build your ecosystem. 🐟

  4. 4

    A simple food chain in a pond: algae → water flea → small fish → big fish. Each arrow means 'eaten by'. Let's see how energy flows! 🌿

  5. 5

    Put these in the right order to make a food chain: 🐇 (rabbit), 🌿 (grass), 🦊 (fox). Which is first?

  6. 6

    In a food chain, what does the arrow mean? 🌿→🐇

  7. 7

    What do we call a living thing that makes its own food (like a plant)? 🌱
