What does a high population density indicate?

o the area is being overfished.

o the species is likely to face extinction.

o there is no other place for that species to live.

o food supply is high and the number of predators low.

Food supply is high and the number of predators low.

Explanation:

It seems that some key elements in what determines population density are

extrinsic factors such as  the supply of food and, the importance of predation in terrestrial systems. Predator removal generally increases population numbers, this paired with an extensive supply of food will bring about high density in population.

Answer    The last option: Food supply is high and the number of predators low

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
