Explanation / Answer

1) =er . = finite rate of increase ofpopulation. Plug in the values you have above. 2) Temperate lake thermoclines are more pronounced (anddeeper) in the b) summer. 3) The more seeds produced, the smaller the seed. 4) b) is smaller when food is abundant and concentrated. Itvery much depends on the animal. Herbivores, for example, need tohave enough space for plant life to regrow after they've eaten it.They may need a larger area. But if you consider animals that coverlarge territories, like the mountain lion, their prey is dispersedthroughout the territory. But predators in the forest have a lotless area and lots of prey within there. 5) d) immigration. The rescue effect occurs when immigrantsfrom one population migrate to a smaller population and save itfrom extinction. 6) I'm pretty sure this is b) biodiversity. I think densitywould look more at one species rather than the diversity ofthem.
