I believe it's saprotrophs
Answer: B) Predator/prey
=========================================================
Explanation:
The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.
The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.
At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.
This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.
Answer: A
Explanation:
Oxygen makes up another 20 to 21 percent of our atmosphere. It's essential for life on Earth, and interestingly enough, it is poisonous when highly concentrated. Our concentration of 20 to 21 percent seems just right.
The meter is the basic measurement unit for length. It has submultiples (centimeter, milimeter, micrometer) and multiples (kilometer).
100 cm = 1 m
1000 mm = 1 m
1000000 micrometers = 1 m
1000 m = 1 km
<u>Answer:</u> Erosion
<em>The process in which there is a wearing down on the surface on the earth which goes through the erosion is called gradation.</em>
<u>Explanation:</u>
There is a certain force which is the cause for the <em>formation of earth’s surface and that force is called as endogenic forces. </em>
There may come up a question about how the <em>surface of the earth</em> is not even, the reason is due to exogenic process failing to even out <em>the variation of the land.</em>
