In the 1850s , Charles Darwin described the struggle for life.The plains of the serengeti in Africa provide an excellent example of this.Living things interact and compete together.The fittest ones survive.Over time a species gradually changes and improves its chances of survival.The fiercest predators eat well but the fastest prey escape and live to reproduce.If a species fails to adapt and improve it becomes extinct, like the dinosaurs.
All special interact with each othere and with their environment. Humans are upsetting the Earth`s balance but we can now reverse some of these changes. Sustainable development and conservation programmes
show that we need not destroy hold the key to restoring this delicate balance.
In this topic you will learn that
- animals and plants depend upon each othere
- all organism are adapted to their environment
- there is often competition between organisms for resources
- natural selection is a long process over many genertions.
