PART 3: Biotic anf Abiotic Factors

What are biotic factors + examples

Living things in the environment (e.g. animals, plants, bacteria)

What are abiotic factors + examples

Non-living part of the ecosystem which shapes its environment (e.g temperature, light, water availability, ocean currents)

What do biotic and abiotic factors limit + why?

They limit population size distribution, meaning they control how many organisms live in a place and where they live

Explain how they limit population size distribution

Example.

• If there’s not enough water (abiotic) many plants and species can’t survive.

• If one species has too many babies (biotic) it might eat all the food, leaving the others (and itself) to starve

Therefore, what effect does the uncontrolled growth of any species have

It has negative effects on the environment and limits the survival of the same and other species

How do biotic and abiotic factors interact

Through

• Competition: for food, light

• Predation: one animal eats another
