Which of the following describes a relationship of predator-prey

I couldn't find the options to answer this question online, but I'll give you an explanation so you can answer it yourself.

Predator-Prey relationships occur in nature where one species hunts the other to feed on it. In this case, the hunter is the predator, who will kill the prey after stalking it in order to feed.

This type of relationship does not occur only in carnivorous animals such as a lion and a deer, but can occur between an insect that eats a plant, for example.

Given this explanation, you should see which option is best suited to this description.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
