Background:

         Why should we care about Bio Diversity?  What are Ecosystems and how do they play a role in life?

 

Ecosystems

           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.[1] 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.[1] The entire array of organisms inhabiting a particular ecosystem is called a community.[1] In a typical ecosystem, plants and other photosynthetic organisms are the producers that provide the food.[1] Ecosystems can be permanent or temporary. Ecosystems usually form a number of food webs.[2]

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

 

Vocabulary

           Abiotic - The nonliving elements of an ecosystem. 

                      Eg. Air

 

           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.
