Contents
Key Stage 4
Meaning
Biotic environmental factors are the conditions of a habitat caused by other organisms.
About Biotic Environmental Factors
Biotic environmental factors include:
- Diseases
- Large populations;
- Consuming too much food.
- Using too much of the fresh water
- Blocking out light
- Parasites
Examples
- Disease is a biotic factor which can lower the population of a specific organism within a community. This will have an effect on other organisms in the community due to the feeding relationships between them. If a disease reduces a population then the population of the organism that eats it will decrease while the population of organisms that are eaten by it will increase.
