Students should be able to explain how a change in a biotic factor might affect a given community given appropriate data or context.
Biotic (living) factors which can affect a community are:
- availability of food
- new predators arriving
- new pathogens
- one species outcompeting another so the numbers are no longer sufficient to breed.
hrStudents should be able to extract and interpret information from charts, graphs and tables relating to the effect of biotic factors on organisms within a community.
