The location where an organism lives, such as a woodland.

The specific location of an organism, such as a tree or a leaf for certain insects

All the individuals of a species interacting and breeding with one another in a habitat.

All the members of different populations of species interacting within a Habitat: I.e All of the organisms within a woodland.

The number of individuals of a population, i.e how many maize plants in a field.

The number of individuals of a species in a habitat (same as Population size.)

How the individuals of a population are spread out over an area.

The progressive replacement of a dominate community by another until a climax community is reached.

The succession that occurs on desolate, barren and previously inhospitable areas, such as after a glacier recceeds or lava flow destroys an area.

The most productive and diverse community that an area can support. It is relatively constant with the species present but alterations are always occuring.

Hardy species which are adapted to harsh abiotic environments, they help the formation of soil by breaking down rocks and converting energy to organic matter.

This is when Human Activites cause the formation of a different climax community than would normally be formed. Use as mowing a lawn would cause no woody trees even though the soil can support them.

Difference between primary and secondary succession?

Primary Succession in an area that has no viable soil and is when a climax community is reached for very harsh abiotic environment. Secondary is the production of climax community from the disturbance of a primary succession. When soil is already present.

Name they type of species which first colonise an area:

Pioneer Species. (Marram Grass etc)

As succession continues, what happens to the biodiversity of an area:

It will increase, more organic matter and better soil quality will be able to support more complex and varied plant life, which in turn support more animal species.

How can succession be prevented?

Mowing grass, Harvesting crops, Destruction of woodlands.

Question	Answer
Habitat:	The location where an organism lives, such as a woodland.
Microhabitat:	The specific location of an organism, such as a tree or a leaf for certain insects
Population~:	All the individuals of a species interacting and breeding with one another in a habitat.
Community:	All the members of different populations of species interacting within a Habitat: I.e All of the organisms within a woodland.
Population Size:	The number of individuals of a population, i.e how many maize plants in a field.
Abundance:	The number of individuals of a species in a habitat (same as Population size.)
Distribution:	How the individuals of a population are spread out over an area.
Define Succession:	The progressive replacement of a dominate community by another until a climax community is reached.
Primary succession:	The succession that occurs on desolate, barren and previously inhospitable areas, such as after a glacier recceeds or lava flow destroys an area.
Climax Community:	The most productive and diverse community that an area can support. It is relatively constant with the species present but alterations are always occuring.
Pioneer Species:	Hardy species which are adapted to harsh abiotic environments, they help the formation of soil by breaking down rocks and converting energy to organic matter.
Plagioclimax:	This is when Human Activites cause the formation of a different climax community than would normally be formed. Use as mowing a lawn would cause no woody trees even though the soil can support them.
