Answer:
II and III only
Step-by-step explanation:
The Endangered Species Act is an environmental law in the United States dedicated to the protection and restoration of endangered species. It includes three elements:
- Preventing endangered species from being killed or harmed (usually making it illegal for people to hunt members of the said species);
- Restoring healthy populations (usually by breeding individual members of the species in captivity and afterward releasing them into the wild);
- Protecting habitat essential to these species’ survival.
Habitat fragmentation, followed by population fragmentation and ecosystem decay, is a process in which large habitats get divided into smaller, isolated patches of habitats. It is one of the causes of species endangerment and extinction, so only options II and III are correct.
