Explanation:
The major effect of oil spilage is that it impairs or hampers photosynthesis.
Photosynthesis is the process where green plants manufactures their own food in the presence of sunlight and water.

In the absence of sunlight, plants are unable to manufacture their food.
They are also unable to receive carbon dioxide from the environment.
