Answer: 4 per m2

To find out the population density of a certain species, you must divide the number of organisms living in that habitat over how big the area is. In this case, because there are 20 mice in an ecosystem that is 5 square-meters big, then there would be 4 mice in every square-meter.

Answer:

4 per m2

Explanation:

20 devided by 5 = 4 so 4 per meter.
