The first statement is true, while the second statement is false.

Explanation:

Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.

In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:

50 x 4 = 200

We got 200, meaning that 200 square meters of grass will support a population of 50 mice.

In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:

10 x 10 = 100

We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.
