Community Interactions

When two populations share the same habitat and niche, this leads to

Competition between individuals of the same species

• interspecific

• intraspecific

• demographic

• commensal

In the event that competitive exclusion happens, the less dominant species will

• show logisti growth towards the carrying capacity

• drop its population

• show exponential growth

• begin to coexist with the dominant species

A way to reduce competition between populations and communities in order to coexist; may include change in time of activity or food preference.
