How can the environment affect population sizes?

Food, water, shelter, predation, and density are all things that can allow a population to increase or cause it to decrease. Limiting factors like food and water are necessary resources for all organisms without them they will die so these factors directly affect any population size. Hope this helps :)

More people require more resources, which means that as the population increases, the Earth's resources deplete more rapidly. The result of this depletion is deforestation and loss of biodiversity as humans strip the Earth of resources to accommodate rising population numbers. Food, water, shelter, predation, and density are all things that can allow a population to grow or cause it to decline. Limiting factors like food and water are necessary resources for all organisms; without them they will die so these factors directly affect population size.

Brainliest please if it helped!
