Species
A group of organisms that interbreed and produce fertile offspring. E.g a tiger - a single species with six subspecies surviving with 3 extinct
1 of 8
Population
A group of organisms of the same species living in the same area at the same time + are capable of interbreeding. E.g the number of Indochinese Tigers.
2 of 8
Habitat
The environment in which a species normally lives. E.g the habitat of the Indochinese tiger.
3 of 8
Niche
A species' share of a habitat and the resources in it. An organisms ecological niche depends not only on where it lives but also what it does. E.g The tiger's niche is that of a top carnivore.
4 of 8
Community
A group of populations living and interacting each other in a common habitat. E.g In the community of an Asian rainforest
5 of 8
Ecosystem
A community of interdependent organisms and the physical environment they inhabit. E.g Rainforest ecosystems have a large biomass of trees with a canopy of over 50m in height.
6 of 8
Trophic Level
The Position that an organism occupies in a food chain, or a group of organisms in a community that occupy the same position in food chains. E.g Herbivore
7 of 8
Producers
In most ecosystems these are green plants or algae, photosynthetic organisms that form the base of the food chain. They are also called autotrophs, meaning self feeding. E.g Lowland Oak
