Here's two examples:
* increase or decrease in a prey population - this is a biotic change for a predator. Examples are snowy owls that prey on lemmings; and salmon that prey on krill.
* outbreaks of a pathogen that causes an epidemic in a population

There are two types abiotic and biotic. Abiotic are non living things and your chemical and physical aspects of the enviroment. Biotic is the living things in the enviroment as well as anything caused by living things.
An example might be the amount of vegtation in a area

Anything biological that is changing the in the environment: population size of each living organism, vegetation, community composition, food availability, reproductive success.
Hope this helps!
