Answer:

Stagnant water refers to water that is not flowing or moving. It can be found in puddles, ponds, or containers that have collected rainwater. Stagnant water provides an ideal breeding ground for various organisms, including mosquitoes.

Mosquitoes:
Mosquitoes are small flying insects that require water to complete their life cycle. Female mosquitoes lay their eggs on the surface of stagnant water. The eggs hatch into larvae, which are commonly known as wigglers. The larvae live in the water and feed on organic matter. They go through several molting stages before transforming into pupae. Pupae are also aquatic and do not feed. Finally, adult mosquitoes emerge from the pupae and fly away to find a mate and feed on blood.

Why stagnant water is ideal for mosquito breeding:
- Stagnant water provides a stable environment for mosquito eggs, larvae, and pupae.
- The lack of water movement reduces the chances of the eggs or larvae being washed away.
- Stagnant water usually has a higher concentration of organic matter, which provides food for the larvae.
- The warm temperature and presence of nutrients in stagnant water promote the rapid development of mosquito larvae.

Preventing mosquito breeding:
To prevent mosquito breeding in stagnant water, it is important to take the following measures:
- Eliminate any stagnant water sources around homes, such as empty containers, clogged gutters, or old tires.
- Regularly clean and maintain birdbaths, fountains, and other water features.
- Keep swimming pools properly treated and maintained.
- Use mosquito repellents and protective clothing when spending time outdoors, especially during peak mosquito activity periods.

Conclusion:
Stagnant water provides an ideal breeding ground for mosquitoes. The lack of water movement, presence of organic matter, and favorable temperature conditions allow mosquito eggs, larvae, and pupae to thrive. It is important to prevent the accumulation of stagnant water to reduce mosquito populations and the spread of mosquito-borne diseases.
