In aquatic ecosystem, human activities may accelerate the process of:
Correct answer: A. Eutrophication
- A. Eutrophication
- B. Photosynthesis
- C. Decomposition
- D. Recycling
Explanation
Option A is correct since Eutrophication is the process in which the water body has an enriched amount of nutrients and thus more life and decaying bodies which cause smell. And this process is enhanced by human activities like use of washing powders and fertilizers.Option B is incorrect because Photosynthesis is the process by which plants prepare their food by using sunlight and this process cannot be accelerated by human activities.Option C is incorrect because Decomposition is process of decaying dead matter and done by bacteria human activities have no role.Option D is incorrect because Recycling is process by which old things are reused.
