The place where an organism, species or population lives.
1 of 23
Population
All individuals of a species living in a particular area.
2 of 23
Exoskeleton
A skeleton on the outside of an organism, such as insects.
3 of 23
Turbulence
The roughness of the environment caused by chaotic air to water flow.
4 of 23
Heterotroph
An organism that gains its organic compounds for energy and growth from other organisms.
5 of 23
Cellulase
An enzyme that digests cellulose that is produced by some bacteria, fungi and protozoans.
6 of 23
Symbiosis
A relationship between organisms of different species that live together. One benefits while the other species may benefit, be unaffected or suffer. E.g. +/- relationship.
7 of 23
Mycorrhizal Fungi
Symbiotic fungi associated with plant roots that gain carbohydrates from the plants and aid the uptake of nutrients, such as phosphates from the soil by plants.
8 of 23
Pollination
The transfer of the male plant gametes onto the female part of a flower, resulting in fertilisation or seed production.
9 of 23
Community
A community of species refers to the populations of all species living in a particular area.
10 of 23
Taxonomy
The study of organisms to assess how they might be grouped or classified.
11 of 23
Taxon
A group of organisms based on their biological similarities.
12 of 23
Genus
A group of closely related species.
13 of 23
Ecosystem
The community of organisms living in an area, their inter-relationships and interactions with their abiotic environment.
14 of 23
Biome
A large geographical region with particular climatic features, in which a characteristic, unique community of species live. E.g. coral reef.
15 of 23
Ecological Succession
The sequences of changes in community composition that changes as an area is colonised and develops until a climax community is eventually produced.
16 of 23
Lithosere
The sequence of changes in community composition as bare rock is colonised and becomes a terrestrial climax community.
17 of 23
Autotrophs
An organism that can capture light or chemical energy from the environment to make high-energy substances, such as carbohydrates. They include photoautotrophs and chemoautotrophs.
18 of 23
Edaphic
A factor related to soil, particularly as it affects living organisms.
19 of 23
Density Independent Factors
A factor that is not influenced by the population density of the species that may be affected. E.g. drought, volcanic eruption.
20 of 23
Density Dependent Factors
A factor whose effect is affected by the density of the population. E.g. food supply.
21 of 23
Carrying Capacity
The greatest population that can be supported sustainably in an area.
22 of 23
Sigmoidal Population Growth
The growth pattern of a population where abundant resources allow rapid growth followed by population stabilisation as the carrying capacity is reached.
