Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
What biotic factors affect birds?
Tree functional diversity was the most important habitat predictor for birds, while bats responded more to understorey structure. The best biotic predictors for birds were spider abundance and defoliating insect activity, while only bat functional evenness responded positively to insect herbivory.
Are animals a biotic factor?
Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem.

What are some examples of biotic factors?

- Producers (Autotrophs)
- Consumers (heterotrophs)
- Decomposers (detritivores)
Is hair biotic or abiotic?

Is plankton biotic or abiotic?
Moreover, the phytoplankton community acts as a biotic influence and interacts with the bacterial community through direct or indirect interactions including mutualism, commensalism, parasitism, amensalism and competition (Kazamia et al. 2016; Kirchman et al.
Is grass biotic or abiotic?
Grass is a biotic component of the environment. Biotic factors are the living components of an ecosystem.
Which is an example of abiotic factor?
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.
