Study Notes
Non-Living Factors in Ecosystems
- Abiotic factors refer to non-living components of an ecosystem, such as light, temperature, water, and nutrients.
Competition in Ecosystems
- Intraspecific competition occurs when individuals of the same species compete for resources.
- Interspecific competition occurs when individuals of different species compete for resources.
Factors Affecting Ecosystems
- Biotic factors, including living organisms, affect the number and types of organisms an ecosystem can support.
- Abiotic factors, including non-living components, affect the number and types of organisms an ecosystem can support.
Interactions in Ecosystems
- Predation: one species captures and consumes another species.
- Mutualism: two species benefit from each other's presence.
- Competition: one species affects another species by competing for resources.
Species Interactions and Resource Competition
- When one species affects another species in competition for the same resources, it is an example of interspecific competition.
- Competition for resources can affect the number and types of organisms an ecosystem can support.
