   Deforestation is the opposite of conserving plants. Planting trees, sustainable harvesting, and protecting endangered species are all methods of conservation.

2. Explain the significance of seed banks in plant conservation.

   1. They store seeds for future planting to preserve genetic diversity
   2. They are used for commercial seed production
   3. They help in controlling plant diseases
   4. They attract birds and insects to the area
   Show answer

   Answer: A. They store seeds for future planting to preserve genetic diversity

   Seed banks act as repositories of plant genetic diversity, ensuring the survival of plant species even if their natural habitats are destroyed.

3. What is the role of national parks in wildlife conservation?

   1. To provide a place for hunting and fishing
   2. To allow unrestricted human development
   3. To protect biodiversity and endangered species

5. Evaluate the effectiveness of different conservation strategies, such as captive breeding programs versus habitat preservation, considering their costs and long-term sustainability.

   1. Captive breeding is always more effective
   2. Habitat preservation is always more expensive
   3. Both have advantages and disadvantages depending on the species and context
   4. There is no difference in their effectiveness
   Show answer

   Answer: C. Both have advantages and disadvantages depending on the species and context

   The best conservation strategy depends on various factors, including the species' biology, the state of its habitat, and available resources.
