What is an Ecosystem?

Abiotic Factors

Abundance

Factors affecting ecosystems arising from human activity

Living factors in an ecosystem

Final stable community at the end of the process of succession

When succession is not completed due to human activity

Factors that have a greater effect on a population when the population is large

Description of where a particular species can be found

Interaction between the living and non living components in a given area

Factors related to soil

Type of feeding relationship between a herbivore and plants

Place where an organism lives

Competition for resources between organisms of different species

Competition of resources between organisms of the same species

Type of bar chart representing distribution and abundance of organisms

Feeding/living arrangement between two organisms where both benefit

Description of the relational position of a species in its ecosystem

Relation ship where one organism feeds from the other living organism

Pioneer community

Feeding relationship where one organism kills and eats the other

Succession which occurs in an area where no previous communities existed

Succession which occurs on land that has been cleared, where communities existed before

Communities that develop during succession between the pioneer community and the climax community

Animal that does not move, e.g. attached to rocks

Measure of the spread of data about a mean

Process of changes in a community over time brought about by the changes in abiotic factors caused by previous communities

Description of the profile of an area, including altitude, slope, aspect and drainage

The line across and area to be inspected

Feeding level in a food chain or web

Adaptation of plants that enable them to survive dry conditions

Organisms who are able to synthesise organic compounds from simple molecules, such as carbon dioxide

Organisms who obtain their food and energy from organic compounds

Organisms who are autotrophic at the start of a food chain

Organisms who are heterotrophic and feed on producers (herbivores)

Organisms that feed on primary consumers

An organism that feeds on dead and decaying matter, including bacteria and fungi
