Which two natural resources will be most affected as people try to meet the growing demand for food?
Jet001 [13]

Answer:

water and land

Explanation:

I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.

the grand canyon was carved, separating what had once been a single population of squirrel into two seperate populations. what d
tatiyna

Answer:

They became different.

Explanation:

Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.
