The lessons... |
There are millions of different organisms on Earth. They all interact with each other and with their environment. The best adapted organisms are the ones most likely to survive.
You learnt about the amazing range of living organisms, and how biologists are able to sort this variety of life into groups. Along with grouping, you studied the ideas of feeding relationships and energy flow through the food chain. Death and decay are part of this, and so is recycling. The ways in which different organisms compete with each other for limited resources was investigated. You learnt about the fantastic ways that plants and animals have become adapted to survive. You learnt how all this life evolved. Finally, you examined some of the big issues of the day: the effects of human pollution, and how we can all live a sustainable lifestyle. |
