Adaptations, Interdependence And Competition
Akopọ
Pick any patch of ground: a strip of sand dune, a puddle in a hot spring, the fur behind a dog's ear. Something already lives there, and whatever it is, it is holding that place against everything else that would like it. Living space is never handed out. It is won, held, and eventually lost, and the winners are the organisms whose bodies and habits happen to fit the conditions best.
This lesson is about that fit. You will sort out what plants and animals are actually competing over, and why two organisms that want the same thing cannot both have all of it. You will see why the harshest competition of all is between members of one species, and then look closely at organisms whose bodies and habits match the place they live in: a bear on the ice, a camel in the sand, a plant that has to survive on almost no rain, and the microorganisms working quietly through a compost heap.
Awọn Afojusun
- To survive and reproduce, organisms require a supply of materials from their surroundings and from the other living organisms there.
- Plants often compete with each other for light and space, and for water and nutrients from the soil.
- Animals often compete with each other for food, mates and territory.
- Organisms, including microorganisms, have features (adaptations) that enable them to survive in the conditions in which they normally live.
