The answer is 6 per m2.
A population density is the number of animals per 1 m2.
So, this problem can be solved by using a proportion:
If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.
60 raccoons : 10 m2 = x raccoons : 1 m2
60 raccoons : 10 = x raccoons
x raccoons = 6 raccoons
Thus, the population density is 6 raccoons per m2.

Crayfish are invertebrates which means they don't have a backbone. They are also arthropods, which means that they have a protective exoskeleton on the outside of their body. Other arthropods include insects, spiders, and centipedes. Crayfish continually shed their exoskeleton and regrow a new one. During this transition is when they are most vulnerable to predators because they aren't protected by their outer shell.
Crayfish are found all over the world in many different freshwater environments, such as rivers, creeks, springs, and swamps. But this doesn't necessarily mean that you will be able to find them. They are somewhat cryptic because they dig out homes for themselves under rocks and blend in well with their environment. Crayfish will ardently defend this dwelling against intruders using their strong front claws
Grasses are the producers. Gazelles, warthogs, and wildebeests are primary consumers. Lions and cheetahs would be the secondary consumers.
