Ecos\stems, Species and Genetic Diversit\ A species is a partic ular group of organisms that have the same struc ture and c an reproduc e with eac h other. Of the 30 - 100 million possible different spec ies of living things, there are over 1.5 million spec ies of animals and 350.000 spec ies of plants that have been identified b\ biologists. The most suc c essful life form seems to be the insec t. ( Grade 7 Review ) All living things are made up of c ells, need energ\, grow and develop, reproduc e and have adaptations whic h suit them to the spec ific habitat in whic h the\ live. The entire c ollec tion of living organisms, eac h with their own unique c harac teristic s, make up the Earth's biodiversit\. "Biologic al diversit\ refers to the variet\ of spec ies and ec os\stems on the Earth and the ec ologic al proc esses of the\ are a part of." The main c omponents of biodiversit\ are: Ec os\stem diversit\ - the different t\pes of living c ommunities and the environments, suc h as marshes, lakes, streams and forests, in whic h the\ are found Communit\ (populations of different spec ies living in the same area) diversit\ - oc c urs within populations (members of a spec ies that live in a spec ific area and share the same resourc es) of organisms living within a partic ular ec os\stem Spec ies diversit\ - oc c urs within individual organisms of the same spec ies Genetic diversit\ - oc c urs within organisms at a c ellular level, as it desc ribes the variet\...
