Answer/Explanation:
Abiotic factors are non-living factors that can influence an ecosystem. For example, temperature, water, and light.
These are important features for the stability of an ecosystem.
Say for example the temperature was higher than usual for an extended period of time due to global warming. This has a profound effect in many ecosystems, most obviously in the arctic. The high temperatures cause the ice to melt. This means there are less ice sheets on which polar bears can hunt seals. Hunting seals is a rich energy source for polar bears, and they are starving as a result of the increasing temperatures and melting ice. This would cause the seal population to increase, and the fish population to decrease as a result (seals hunt fish).
Another example is water, if there is a drought caused by reduced rainfall, then plants do not have the sufficient water to perform photosynthesis. Photosynthesis is the process where plants make their own food, and without it they cannot survive. Less plants would produce less food for herbivores, who would die out. If herbivores die out, then carnivores lack food too.
