Analogous structures!
Analogous structures are things that look similar and serve similar functions but do not come from a common ancestor.
The example of a nonpoint source of freshwater is the first option: <span>pesticide runoff from farm fields. This is one of the most common nonpoint source of poullution</span>
The answer is K-selected.
<span>The population size of K-selected species is fairly constant
in time, unlike the population size of r-selected species. r-selected species
are usually bellow carrying capacity and the population size is density
independent. On the contrary, K-selected species are usually near or at
carrying capacity and the population size is density dependent. It can be concluded that sperm whales have K-selected populations, since they </span><span>maintain their populations close to carrying capacity.</span>
