Answer:
Impairment of photosynthesis
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.
Water is denser than oil. Therefore, oil floats on the surface of water. Oil on water surface acts as a blanket to sheild plants away from receiving direct sunlight. Sunlight is very important during photosynthesis.
In the absence of sunlight, plants are unable to manufacture their food.
They are also unable to receive carbon dioxide from the environment.
Answer: Reproduction. One must reproduce in order to continue the generational line.
Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce
Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
