Science - B4 - Ecology in the local environment

HideShow resource information
An ECOSYSTEM - all of the living things and their surroundings.
HABITAT - where an organism lives.
1 of 6
A COMMUNITY - is made up of the organisms living there.
A POPULATION - is the number of a particular organism in a community.
2 of 6
NATIVE ecosystems have a wider biodiversity than ARTIFICIAL ecosystems.
e.g Native: woodland, lakes. e.g Artificial: aquariums, parks, gardens.
3 of 6
ZONATION - the gradual change in species distributions across a habitat.
The distribution of organisms can be mapped using a transect line and displayed as a kite diagram.
4 of 6
Capture-recapture data can be used to calculate a population size estimate.

5 of 6
Capture-recapture data assumes -
- No deaths, immigration, emmigration. - Identical sampling methods -survival rates not affected by marking organisms.
