Answer:
a.ii. A predetor is an animal that hunts or kills for food
A prey is the animal that the predetor hunts or kills for food
Explanation:
For example a rabbit is a prey because a fox (predetor) can hunt or kill it.
D. Watershed - a watershed is the area in which runoff, rivers, and streams run into a larger body of water
The body of water experiences eutrophication.
The process of eutrophication takes place primarily in ecosystems with gradual changing waters, mainly in deep lakes. In the depths of the lake, where deposition of dead algae takes place, the aerobic bacteria, which feeds on them proliferate that in turn consumes more amount of oxygen.
Though in the absence of enough circulation of water that is usually found in the case of deep lakes, the bottom of the lake is poorly oxygenated and the bacteria eventually deplete the oxygen found in the deep layers of water. Thus, they can no longer degrade all the dead organic matter and gets accumulated in the sediments. The lake is now considered to be aging.
Anwser is #1 because t<span>he equator is moving faster than the poles and so extends outward a bit due to centrifugal force. That means a point on the equator is a tiny bit farther from the centre of the Earth than the poles. </span>
<span>The gravitational acceleration at the equator is 9.789 m/s^2m, and 9.832 m/s^2 at the pole.</span>
