• There are many different ecosystems such as rivers, mountains, sea, rocky shore, ponds, wetlands, grasslands, forests and deserts, which support different kinds of living things.

• Greet the learners.
• Ask them if they have ever wondered what it would be like to live alone on a remote island. What would they eat?  What would they wear?  How would they build a shelter?  Who would they talk to?
• Imagine that there are no other living things on this island. How long do they think they will be able to survive?
• Allow some time for discussion of the scenario.
• Tell the learners that people, plants and animals need each other to survive.
• Living things are connected to each other; they depend on each other as well as on the non-living things in the environment.
• Ask learners if they can remember what an ecosystem is. Can they remember what they learnt about animal habitats and ecosystems in Grade 5? 
• An ecosystem is an area where living and non-living things depend on each other in many different ways.
