Ecology is the study of organisms and their interactions with each other in their environment.
It can be studied at various levels.

• An organism is the basic unit in ecology. It carries out all the life processes in its body, independant of other organisms. E.g: Humans. fish. tiger, etc.
• Group of individuals of the same species inhabiting a given area form a population. E.g: a school of Rohu fishes in a pond, a pride of lions in a savannah, etc.
• A group of different populations present in an area is called a community. For example, a group of separate populations of fishes, seahorses and other aquatic animals together form a community of aquatic animals in an ocean.
• When multiple biological communities interact with each other and with their physical environment they form an ecosystem.
• A biome is a collection of flora and fauna present in an ecosystem which are adapted to a specific climate. There are different types of biomes present on Earth such as tundra, desert, temperate forest, etc.
• All biomes together on Earth form a biosphere.
