"List four properties of a community and explain the importance of each"... WHAT?!

Question

Okay, I'm doing AP Biology Summer Homework, and that question is confusing me, because in the length of a 24 page (like 8 font) chapter on Community Ecology I cannot find any "four properties." I assume they mean interspecific interactions (Predation, competition, commensalism, mutualism)... but I'm not sure. Help?

Answer 1

Community properties in ecology texts usually refer to things like:

abundance

diversity

complexity

biomass

richness

productivity

stability

The concepts you're describing usually are grouped under "interactions", not properties.
