Answer 2

Weeds that are present on water bodies are mainly algae-like spirogyra, ulothrix, etc.

Explanation:

• These algae are very fast reproducing structures and the speed moving motorboats or blades of the motorboats can easily cut them in pieces and they can reproduce each piece into new organisms.
• This will not only increase their population, but also can form a condition which is called algal bloom, which can cause organisms underwater to be deprived of sunlight and oxygen, and they may die.
