Whatis ecology
What is anecosystem
Ecosystems consistoe a network of habitats and the communities oforganismsassociated
to them
Habitat Placewhere an organismlives
Microhabitat Smallpartof a habitat
Population Groupoforganisms of the samespeciesliving and breedingtogether
Community Populations oe all the different species of organismslivingin a habitat
Niche role oe an organismin a community
Bioticfactors Livingfactors affecting the ability of an organismto survive
Abiotic factors Non living elements of the habitat of an organism
Biosphere largestecosystemin earth divided into smaller partscalled biomes
, Conserving globalbiodiversity
the nature of extinction
Extinctionis the permanent loss ce all membersoe a species
Extinction can belocalised onlyin an area or total lost from Earth
Speciesbecome extinct becausesomethingchanges in their habitat
Criticallyendangered Extremelyhighrisk of extinction in the wild
Endangered Veryhighrisk ofextinctionin the wild
Vulnerable Highrisk oeextinction in the wild
Conservation measures such as habitatprotectionmay remove the threat of extinction
