Visual Analogy Figure 6-11 Resilience to Climate
In this model, the “red” species better tolerate wet weather, while the "yellow"
species better tolerate dry weather. Ecosystems containing just one of those species
change more dramatically than an ecosystem containing both species. Use Models
What does this model suggest about biodiversity and ecosystem resilience?

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

looks like the answer is     c     to me!
