The study of living organisms and their environment.
1 of 13
Biosphere
The part of the planet Earth where life occurs, including land, air and sea.
2 of 13
Ecosystem
A reasonably self-contained area together with all its its living organisms, e.g. oak forest, deep sea, sand dunes, etc.
3 of 13
Habitat
The physical (or abiotic) part of an ecosystem, i.e. a defined area with specific characteristics where the organisms live. Most ecosystems have several habitats.
4 of 13
Microhabitat
A localised specific habitat within a larger habitat, e.g under a rotting log, in a rock pool, etc.
5 of 13
Terrestrial
An ecosystem on dry land.
6 of 13
Aquatic
An ecosystem in water.
7 of 13
Marine
An ecosystem in the sea.
8 of 13
Community
The living (or biotic) part of an ecosystem, i.e. all the organisms of all the different species living in one habitat.
9 of 13
Biotic
Any living or biological factor (e.g. predation, disease, etc).
10 of 13
Abiotic
Any non-living or physical factor (e.g. temperature, humidity, etc).
11 of 13
