Question 64592

What are examples of ecological parameters?

I think an ecological parameter is:
A variable, measurable property whose value is a determinant of the characteristics of an ecosystem.
(From eea.europa.eu)
But what could these parameters be? In other words, what are some examples of ‘parameters’? Can they be both abiotic(e.g.amount of rainfall) and biotic(e.g.species diversity)?
I assume they possibly vary with ecosystem.

P.S. This question is related to my last one. I actually wanted to replace it but it was too late for that. I will appreciate if you answered this one for I have figured out what ecological factors are.
