Sunlight will not be properly absorbed
Explanation:
Plants rely heavily on sunlight to produce their own food through the process called photosynthesis. Photosynthesis occurs in leaves of plants because they contain most of the chlorophyll in the plant. Acid rain weakens the integrity of the plant by dissolving its waxy protective covering. So when the leaves get damaged, it limits their absorption of sunlight which is integral in the food making process of these plants. Limitations will cause a deficiency, or in other words, it will not be able to produce enough food for it to sustain its health.
Natural Selection is not random because the organisms of a species that do not survive have a non-desirable genetic quality, a disease, injury, etc. This leaves the better organisms of a species to survive and reproduce, which creates a stronger and larger species.
