<span>Studying the changes in densities of pocket gophers when large herbivores such as elk are excluded from mountain forests would be an example of studying ecology at the community level.
A community refers to a group of organisms of various species that live in the same location and interact with each other. So, if this scientist is observing gophers and elks, they are looking at the level of communities, not anything more or less.

Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)
Explanation:
Answer: Increase in species numbers and diversity
Explanation:
Upwelling is an oceanographic phenomena in which the water from the bottom layers of the ocean usually above the seafloor get displaced and reach upto the surface layers with the effect of wind currents. The water carries away along with it the nutrients and the organic matter to the surface layers which allows the efficient growth of plant and planktonic diversity which favors the growth of sea animals like fishes and others. Hence, by this way the species diversity and numbers increases by the process of upwelling.
