What this lesson covers
Ecosystems is a 10-part Class 8 Science lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
An ecosystem is all the living things in an area together with the non-living conditions: soil, water, light and temperature. A habitat is where an organism lives; a population is all of one species there; a community is all the populations together.
