Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E. e. eschscholtzii?

E.e. oregonesis

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii, which arose through ring speciation that occurs when a species is geographically distributed in a circular pattern. After this distribution, geographic isolation occurs, causing individuals in each different region to evolve differently, becoming other species, even reaching the point where it is not possible to cross them.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
