AP Biology Review (Part Four)

Dung

________= provides habitats for insects and helps distribute seeds.

Metabolize carbohydrates

________, lipids, proteins as sources of energy hydrolysis (adding water to break down)

Tusks

________ used to dig up riverbed= creates water holes for animals.

Predator prey

______: one species uses another for a f__ood source.

Commensalism

________: one species benefits but the other is not harmed or helped (+ /0)

keystone species

When a(n) ________ is removed, it has a negative impact on other trophic levels as the populations are not in check and may either increase or decrease drastically; the wolves in yellowstone national park created this effect when the moose population grew exponentially without any predator which decreased its food source.

genetic variation

Adaptation: ________ that is favored by selection.

moreAP Daily

The increased coordination or cooperation will create an increase in the food supply or other limited resources that are fought after such as resource partitioning in which both organism face a win- win situation (such as temporal where species use the resource at different times, spatial where they use different habitats, morphological where theres an evolution of different body shapes or sizes or ________ 8.6 Biodiversity.

population size

Fluctuations in ________ can naturally occur at or near carrying capacity.

negative feedback loop

A(n) ________ is regulating so when there is a decrease in the predator species, the prey will increase in size.

Evolution

________ is characterized by change in the egentic make- up in a population over time.

Niche

________ is free of predators or competitors.
