8. How are species diversity and genetic diversity different? (1 point)
Species diversity is evaluated only in ecosystems, while genetic diversity is evaluated in the entire biosphere.
Species diversity measures the number of species in the biosphere, while genetic diversity measures the variety of genes in the biosphere, including genetic variation within species.
Species diversity measures the number of individuals of a species, while genetic diversity measures the total variety of species.
Conservation biology is concerned with species diversity, but not with genetic diversity.

Answer 30

Well the soil won't blow away because the plants won't die :P

What if I told you pesticides are easily water soluble (they get carried in water)

Answer 31

hmm, maybe d because he could be doing a test, But i trullt do not beileve it is b so D, as he might be observing the results
