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

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

answer: grassland biomes are closer to the equator and receive more rain.
