If we count the number of insects on a tree and number of small birds depending on those insects as also the number of larger birds eating the smaller, what kind of pyramid of number would we get?

Which pair of terms most accurately describes the life history traits for a stable population of wolves? iteropparous; K-selected iteroparous; r-selected semelparous; K-selected semelparous; r-selected

Suppose scientists studied a species of plant that grows in shady environments. They measured the size of leaves in two plant populations and found that the size distribution was similar. In addition, they found that plants with larger leaves tended to produce more seeds and that their offspring tended to have large leaves. The scientists also measured the selection differential, S, of leaf size in each population. In population A, S equalled 1 cm². In population B, S equalled 2 cm?. Assume that the heritability of leaf size in the two populations is the same. Predict how the difference in S between the populations will affect the evolution of leaf size in these populations. O After a given number of generations, the leaves in population B will be larger than those in A. Because S indicates variance in leaf size, leaf size will evolve more rapidly in population B than in A. Environment plays a larger role in determining leaf size in population B than in population A. Because S…

The next five questions (questions 11-15) are related to each other. Read all of the scenarios very carefully and in order and select the correct answer. A population of 10,000 blue grasshoppers lives on an island. Most members of the population live among the grasses because they are not very good climbers. Some grasshoppers live in the trees because they are good climbers. One year, a short-legged mouse arrived at the island and ate all grasshoppers within its reach, thus totally wiping out the grasshoppers living in the grasses. Luckily, those grasshoppers that were good climbers were spared. This story is an example of Gene Flow Founder Effect C Natural Selection Genetic Drift
