Detailed explanation-1: -State and federal protections, habitat preservation efforts, and reduced demand for alligator products have improved the species’ wild population to more than one million and growing today.
Detailed explanation-2: -Habitat loss is the primary cause of higher extinction rates. Other causes include habitat changes, over-exploitation of wildlife for commercial purposes, the introduction of harmful nonnative species, pollution, and the spread of diseases.
Detailed explanation-3: -Habitat loss is the leading known cause of population decline.
Detailed explanation-4: -Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
Detailed explanation-5: -Genes, or Genetic Diversity Genetic diversity is arguably the most important level of biodiversity to conserve, because it is the most fundamental.
