Biodiversity and Conservation

Endangered species are prone to become extinct. When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population, massive habitat loss and position at a higher trophic level favor extinction. As forests are the main habitat for the wild animals, their loss favors the extinction of the same.

Habitat destruction, poaching, climate change and lack of resource management have resulted in a decline in biodiversity by leading to the extinction of species. Other factors such as large body size, small population, and position at a higher trophic level also favor extinction of species. When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out.

• Factors such as large body size, habitat loss, and fragmentation (a most important factor), small population and position at a higher trophic level favor extinction.
  
  

Wildlife is an asset for our environment. It needs to be protected to maintain an optimum biodiversity. Some of the reasons for extinction of wild life are:

Endemic species are those species which occur in a restricted area. Seas from the barriers to free intercontinental movement and separates the continents, causing evolution and endemism. Hence, the correct answer is  option C.

An endemic taxon is defined by its limited geographic distribution, meaning it is found exclusively in a specific area.

• Habitat destruction occurs when natural habitats are no longer able to support the species present, resulting in the displacement or destruction of its biodiversity.
• The growth of the human population has impacted the planet and affected biodiversity. The need for food, space and raw materials has resulted in the destruction of habitats and pollution.
  
• Introduction of invasive species causes harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.

Wetlands are facing a number of threats, but they are also resilient ecosystems that can adapt to change. Wetlands are important ecosystems that provide a number of benefits to humans and wildlife.

A biodiversity hotspot is a region with a high concentration of biodiversity, including a large number of endemic species, which are species that are found only in that region.

A mass extinction is a sudden and widespread extinction event that affects a large number of species in a short period of time.

Mass extinctions can be caused by a variety of factors, including asteroid impacts, volcanic eruptions, and climate change.

Sustainable agriculture practices aim to minimize the negative impact on the environment and promote the conservation of biodiversity.

Ocean acidification is not expected to lead to increased biodiversity.

Disease outbreaks are not considered to be a major cause of mass extinction events, as they typically affect only a small number of species.

Mass extinction events can lead to evolutionary opportunities for surviving species, as they may be able to fill the ecological niches left vacant by extinct species.
