Functional Diversity-Question
Within biodiversity, the only one that isn’t clicking for me is functional diversity. I know the definition and i know it looks easy and simply, but how is there a diversity for these processes. Is it the diversity in the amount they do the process or is it the different types of processes? Because we all need energy flow and recycling in our communities so how would that be diverse? Or is it about the rate at which these processes go? I understand the energy flow and all the cycles i just dont get how that could be diverse. Sorry if this seems easy!
Good question, Liza! The way I see it, I view functional diversity as simply the variety of types of matter cycling and enegy flow within ecosystems and the biosphere. I wouldn’t get caught up in the differences in “amounts” or “rates” at which organisms perform these biological/chemical processes. Focus on the fact that there is a wide range and difference in the types of processes organisms take part in. Certain bacteria are responsible for “fixing” nitrogen into usable forms such as ammonia and ammonium ions. Then there are other bacteria, soil bacteria, who help continue the process by converting accumulated ammonia/ammonium ions into nitrite ions and then nitrate ions which are absorbed by plants (nitrification). Other bacteria may break down organic wastes into nutrients that can be used by plants. Try looking at functional diversity as the variety in the types of “roles” or “jobs” or “responsibilities” organims have within ecosystems and the biosphere. I hope that helps, and please correct me if I’m totally wrong, folks! =)
Thanks so much Molly that was a great description and it helped me understand the concept a lot more!!
