Why should we care about Bio Diversity? What are Ecosystems and how do they play a role in life?
An ecosystem consists of all the organisms living in a particular area, as well as all the nonliving, physical components of the environment with which the organisms interact, such as air, soil, water, and sunlight. It is all the organisms in a given area, along with the nonliving (abiotic) factors with which they interact; a biological community and its physical environment. The entire array of organisms inhabiting a particular ecosystem is called a community. In a typical ecosystem, plants and other photosynthetic organisms are the producers that provide the food. Ecosystems can be permanent or temporary. Ecosystems usually form a number of food webs.
Ecosystem is a functional unit consisting of living things in a given area, non-living chemical and physical factors of their environment, linked together through nutrient cycle and energy flow
Abiotic - The nonliving elements of an ecosystem.
Biotic - The living elements of an ecosystem.
Eg. Plant and animals.
Ecosystem - A habitat in which plant, animals, and microorganisms interact with each other and their surroundings.
Eg. Oceans and Forest
Habitat - the area where an organism normally lives.
Eg. Sharks primarily live in the oceans west of the US.
