What might happen to the animals in an ecosystem if the available abiotic resources decreased?
A. The animal populations would not be affected because abiotic
resources are not needed for survival.
B. All the animals would perish.
C. Some animals would perish, while others would migrate to a new
location.
D. All animals would migrate to a new location.

Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature. ... Without water, animals become weak and confused, and they can die if they do not rehydrate. For example, if a plant is adapted to low temperatures and the specific are where it lives, has a change in its temperature(thanks to global warming!), this plant will die and this area will no longer support life, which is due to the change in abiotic factor (temperature) Many forces influence the communities of living organisms present in different parts of the biosphere (all of the parts of Earth inhabited by life). The biosphere extends into the atmosphere (several kilometers above Earth) and into the depths of the oceans. Despite its apparent vastness to an individual human, the biosphere occupies only a minute space when compared to the known universe. Many abiotic forces influence where life can exist and the types of organisms found in different parts of the biosphere. The abiotic factors influence the distribution of climates, flora, and fauna. so the answer is C
