Q

A
- food availability
- new predators
- new pathogens
- competition
2
Q
How is food availability a factor which can affect a community?
A
more food means organisms can breed more successfully and therefore the population can increase in numbers
3
Q
How are new pathogens a factor which can affect a community?
A
when a new pathogen arises the population has no resistance to it so they can be wiped out quickly
4
Q
How is competition a factor which can affect a community?
A
if one species is better adapted to the environment than another, then it will outcompete it until the numbers of the lesser adapted species are insufficient to breed
