Introduction
Ecology studies
the interactions among organisms and between the organism and its physical (abiotic) environment.
Ecology deals with four levels of biological organization –
Organism- a living entity that can function on its own.
Populations- the sum of all living organisms of the same species living in a particular geographical area.
Communities- a group of people living together in one place.
Biomes- a large geographical area of various plants and animals.
Organisms and Population
Different organisms are adapted to their environments for survival and reproduction—regional and local variations such as temperature and water.
The rotation of the earth around the sun and the tilt of its axis causes annual variations in the intensity and duration of the temperature, which results in distinct seasons. Temperature and yearly precipitation variations, such as rain and snow, form major biomes such as deserts, rainforests, and tundra. The light within each biome leads to the formation of a wide variety of habitats.
