Female anopheles mosquito is the host of plasmodium,and the Anopheles mosquitoes have been found in small, temporary rain pools I.e.ponds ,if  all ponds and puddles are destroyed ,the host will not grow ,as result the plasmodium parasites likely to be destroyed.

The correct answer is option 'D' - Plasmodium.

Explanation:
Plasmodium is a parasite that causes malaria, a life-threatening disease. Malaria is transmitted through the bite of infected female Anopheles mosquitoes. These mosquitoes breed in stagnant water bodies like ponds and puddles. Therefore, if all ponds and puddles are destroyed, the breeding grounds for mosquitoes will be eliminated, leading to a decline in the mosquito population. Consequently, the transmission of Plasmodium and the spread of malaria will be significantly reduced.

Here is a detailed explanation of why Plasmodium is likely to be destroyed if all ponds and puddles are destroyed:

1. Breeding grounds for mosquitoes: Ponds and puddles provide ideal conditions for mosquitoes to lay their eggs. The stagnant water allows the eggs to hatch and develop into larvae, eventually becoming adult mosquitoes. Without these water bodies, mosquitoes will struggle to find suitable breeding sites, reducing their population.

2. Mosquitoes as vectors: Female Anopheles mosquitoes are the vectors responsible for transmitting the Plasmodium parasite. When these mosquitoes bite an infected human, they ingest Plasmodium along with their blood meal. The parasite then undergoes development within the mosquito before it can be transmitted to another human through a subsequent bite. By eliminating the breeding grounds for mosquitoes, the chances of Plasmodium transmission through mosquito bites will decrease.

3. Disruption of the Plasmodium life cycle: The Plasmodium parasite has a complex life cycle that involves both humans and mosquitoes. The destruction of ponds and puddles will disrupt the life cycle of Plasmodium by reducing the availability of mosquito vectors. This disruption can inhibit the transmission of Plasmodium and eventually lead to its decline or possible eradication.

4. Control measures: Destroying ponds and puddles is one method of controlling mosquito populations and reducing the spread of malaria. Other control measures, such as the use of insecticide-treated bed nets, indoor residual spraying, and antimalarial medications, work in conjunction with eliminating breeding sites to combat malaria effectively.

In conclusion, if all ponds and puddles are destroyed, the breeding grounds for mosquitoes will be eliminated, leading to a decline in the mosquito population. This reduction in mosquito numbers will disrupt the transmission of the Plasmodium parasite, potentially leading to the destruction or significant reduction of Plasmodium as an organism. Therefore, the correct answer is option 'D' - Plasmodium.
