Final answer:
False. About one-third of all amphibian species face the threat of extinction. The Amur Leopard is endangered due to habitat loss and poaching. The Rhino is endangered because of poaching and habitat loss.
Step-by-step explanation:
1. False. About one-third of all amphibian species face the threat of extinction due to habitat loss, pollution, climate change, and the introduction of non-native species. The reasons for endangerment may vary across taxonomic groups and regions, but for birds and amphibians, habitat destruction is the most pervasive threat.
2. The Amur Leopard is endangered mainly due to two reasons: habitat loss caused by human development and poaching. The high human population growth in the region places a strain on the leopard's natural habitat, making it difficult for them to survive.
3. The Rhino is an endangered species primarily because of two causes: poaching for their horns and habitat loss due to human development. The demand for rhino horn in black markets drives illegal hunting, which poses a significant threat to their populations. Additionally, habitat destruction limits their ability to find suitable food and shelter.
4. The Hawksbill Sea Turtle faces three major threats: habitat loss through coastal development, pollution such as oil spills and marine debris, and overexploitation for their shells and eggs.
5. To help these endangered species, we can take several actions: (1) Support conservation organizations financially or through volunteering; (2) Raise awareness about the importance of protecting endangered species through education and advocacy; (3) Reduce our impact on the environment by practicing sustainable living habits, such as reducing waste and conserving resources; (4) Report any illegal activities related to wildlife poaching and trade; (5) Support legislation and policies that protect endangered species and their habitats; (6) Encourage responsible tourism practices that prioritize conservation and minimize negative effects on wildlife and their habitats.
