Explanation:

• First question: Black rhinoceros population declined mainly due to poaching for their horns (used in traditional medicine in some cultures and for ornamental purposes). Increased reproduction rates would help population grow, natural migration patterns are normal and not a major decline factor, habitat restoration would aid population.
• Second question: Biodiversity is defined as the variety of life on Earth (including variety of species, genetic variety within species, and variety of ecosystems). Extinction of species reduces biodiversity, controlled environment in ecosystems is not the definition, and it's not a term for climate - change effects.
• Third question: Protected areas like national parks provide safe havens for endangered species. Encouraging habitat destruction, introducing invasive species deliberately, and promoting over - hunting of protected species are all negative for conservation.
• Fourth question: Implementing captive breeding programs is a conservation strategy for endangered species. Encouraging habitat destruction, promoting over - exploitation, and introducing invasive species deliberately are harmful.
• Fifth question: Bee population decline threatens pollination (many plants rely on bees for pollination) and thus food supply. It doesn't increase food production or improve ecosystem health, and has a significant impact.
• Sixth question: Sustainable resource management focuses on ensuring resources aren't depleted beyond recovery. Depleting ecosystems beyond recovery and exploiting resources indefinitely are not sustainable. Regulating ecosystems to enhance biodiversity is a part of conservation but not the main focus of sustainable resource management in the context of resource use.
• Seventh question: The primary goal of conservation is not to promote habitat destruction (which is bad for species), maximize economic gains (though there can be economic benefits from conservation in a long - term sustainable way, it's not the primary goal), or increase human population growth. It is mainly about protecting species and their habitats.

Answer:

1. b. Poaching for their horns
2. d. The variety of life on Earth
3. a. By providing safe havens for endangered species
4. a. Implementing captive breeding programs
5. c. Threatened pollination and food supply
6. a. Ensuring resources aren't depleted beyond recovery
7. (No correct option shown in the provided seventh - question options as the main goal of conservation is protecting species and habitats. If we assume the intended correct idea among the given options is not fully there, but if we had to choose the least wrong, none of the given options a - c are correct. But if we consider a more comprehensive view, conservation aims to protect biodiversity and ecological integrity)
