Area measuring 5 m² contains 50 earthworms what is the population density of the earth worms
Darina [25.2K]

The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:

1,000 x 1,000 = 1,000,000 km²

Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:

1,000,000 x 10 = 10,000,000

So we have a density of 10 million earthworms per square km.

Georgia [21]
The answer is right below.

The bulk of this species’ diet consists of fish in the teleost infraclass, including dragonfish, rattails, anglerfish, and more. They are also known to feed on crustaceans and cephalopods like squid.

These sharks will prey on fish found both on the sea floor and in the water column. Because they are so slow moving, scientists believe these sharks are ambush predators. Their pinkish-red skin actually blends in when in the deep sea.

Describe some changes that occurred during the process of human evolution by comparing the first primates to the first hominids?
wolverine [178]

Answer:Rather, it could look more like one branch or the other branch, or something else entirely. Did the common ancestor of humans and chimps conform to the ape-man myth and live in the trees, swinging from vines? To answer this, we have to focus not only on anatomy but on behavior, and we have to do it in a phylogenetic context.
