Mass extinction is an event that is involved in the extinction of very large populations of biodiversity present on the Earth. It occurs when the rate of extinction is more than the rate of
Summary Introduction
To determine:
The criteria decide which species will live and which will die are based on.
Introduction:
The endangered species is a species whose number has fallen to a critically low level and are likely facing the threat of extinction. The extinction of the species occurs due to loss of habitat and due to loss of genetic variation.

Several alternative definitions of the term species have been proposed, recognizing different species, definitions raises conceptual problems, but it does not have practical implications for conservation true or false
What is the relationship between extinction, its impact on biodiversity, and ecosystems?
When a species becomes extinct, the vacancy of that species allows another species to invade and transform the ecosystem so there is no longer biodiversity, which allows the ecosystem to flourish.
The extinction of plants and animals leaves a vacancy in the biodiversity of the ecosystem, which can cause the ecosystem to collapse.
The extinct plants and animals can come back as a different species, creating more biodiversity within the ecosystem.
The extinction of plants and animals does not have an impact on the biodiversity of an ecosystem.

- Does Totoaba offer any ecosystem benefits? I know their demise is causing the Vaquita to go extinct due to illegal poaching, however, are Totoaba themselves important? Essentially, if Totoaba went extinct, what would happen? *This question is being asked for personal knowledge, not for any school assignments!arrow_forwardThe Endangered Species Act (ESA) of 1973 has helped to slow the destruction of habitat and the loss of species in the United States. There are now many success stories of animals/plants that were on the edge of extinction and now are returning. Even with the success stories there are many who criticize ESA. I want you to give at least 2 examples (with explanation) that show the success and need for The Endangered Species Act. And give 2 reasons why ESA is still criticized after all these years.arrow_forwardIs the species a generalist or a specialist and how does this niche impact the species of the wild. The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common. Raccoons are thriving. Opportunists by nature, raccoons forage on a variety of plants and animals in their ecosystem. Highly inquisitive and intelligent, raccoons use their opposable thumbs to crack open shells, investigate dens, and sift through rocky streams in search of crayfish. Although their habitats are shrinking, raccoons have adapted well to human encroachment and will actively seek food and shelter among the human communityarrow_forward
- To understand the biodiversity of insects in different sites around their community, students performed a leaf litter lab where leaf litter was collected from two sites: one from beneath the trees in an organically managed, commercial landscape established one year ago and one from beneath the trees in a nearby nature preserve that have not been trimmed or managed in over twenty years. The students hypothesized that there would be more insect biodiversity in the leaf litter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with a light shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled container below the funnel, and the species were identified using magnifying lenses and a key. (j) Explain how modifying the experiment to collect samples from wet and dry sites could alter the results of the experiment.arrow_forwardWhat kind of conservation strategies have been or should be implemented to the Hawaiian islands in order to avoid native bird populations declining or going extinct due to avian malaria?arrow_forwardWhat are possible prevention of extinction that we can do alone?arrow_forward

Fund NGOs to implement conservation. Charge visitors for admission and lodging. Land managers have a responsibility to listen to local people's perspectives. Train more scientists. International organizations provide technical and financial support. 1. Many species remain undescribed. 2. Local people unsupportive of the conservation project. 3. Countries face pressure to develop their natural resources. 4. Budgets for conservation areas are inadequate. 5. Government bureaucracy can be inefficient.arrow_forward
