Consider the graphic of the moths. Although not the peppered species, they are spotted and show variation in coloration. Note the ancestral moth species. Predict a situation where the ancestral species diverges into two additional species, now resulting in three, rather than one moth species in the area.
a. Mutations in the moth DNA resulted in variation. Over time, those mutations were passed to offspring. Different species evolved over time.
b. The environment changed over time. Some moths were able to survive the changes; others were not. Eventually, the ancestral species became extinct and two surviving species replaced it.
c. Variation in the ancestral species existed. Depending on the habitat, certain coloration variations provided better camouflage to escape predation. Over time, different species evolved.
d. Variation in the ancestral species existed. Depending on the habitat, different food resources were available. The anatomy of the moths varied and some were able to eat the food available; others were not. Over time, different species evolved.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
