Q

How can niche partitioning increase the biodiversity of a community? What are some ways that species can partition their niches?

A

allowing more than one species access to a limited resource. By dividing up use of the resources in such a way that the species don’t have to compete with one another, a greater number of species are able to survive.

Q

Compare and contrast different interspecies interactions, give examples of each type

A

competition (-/-)
- each species are affected negativley
Mutualism (+/+)
- both species benefit from interaction
commensalism (+/0)
- One species benefit, one is not affected
predation, parasitism, herbivory (+/-)
- one species benefits, one is negatively affected
