Study Notes
Biotic Factors in Ecosystems
- Predation is an example of a biotic factor that could limit a community in an ecosystem, as it can reduce the population size of a species.
- Humans are not a biotic factor that could limit a community in an ecosystem, as humans are an external influence, not a living component of the ecosystem.
Competition in Ecosystems
- Competition as a biotic factor can limit a community in an ecosystem by reducing the availability of resources such as food, water, light, and space, leading to a decrease in population size.
Disease in Ecosystems
- Disease is a biotic factor that can limit the population of a community in an ecosystem, and it does so by increasing mortality rates and reducing reproductive success.
- The primary way in which disease can limit a community in an ecosystem is by reducing the population size and altering the composition of the community, potentially leading to changes in ecosystem processes.
