Populations in Ecosystems Key Terms

?
Intraspecific Competition
Competition where organisms of the same species compete for the limited resources
1 of 14
Interspecific Competition
Competition where organisms of different species compete for the limited resources
2 of 14
Abiotic Factors
Non-living factors that affect living species, e.g. water, temperature, pH
3 of 14
Biotic Factors
Living factors that affect living species, e.g. food, competition, predators
4 of 14
Niche
A role of an organism in a community, e..g what it eats, what eats it
5 of 14
Individual
Each population is made up of many individuals. The genetic and physiological adaptations of an individual organism to environment is an important aspect of ecology
6 of 14
Populations
A population is made up of all the members of a single species living together in the same place at the same time
7 of 14
Community
A group of different species that occurs in the same place at the same time

Ecosystem
A self-contained unit made up of biotic and abiotic factors interacting
9 of 14
Biome
A large, naturally occurring community of flora and fauna occupying a major habitat
10 of 14
Biosphere
The volume of the Earth's surface where organisms can be found

Ecology
The study of inter-relationships between organisms and their environment

Habitat
The place within an ecosystem where a particular population is found
13 of 14
Environment
Sum of all the conditions in the ecosystem outside the organism
