How does animal extinction affect other animals?
“When a predator goes extinct, all of its prey are released from that predation pressure, and they may have big impacts on ecosystems.” “If there are too many deer, for example, they can really change the ecosystem because they can destroy forests, and they also carry disease,” Baldwin said.

What happens if all animals go extinct?
If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.
Are humans causing animals to go extinct?
Scientists at Southampton University say a combination of poaching, habitat loss, pollution and climate change will cause more than 1,000 larger species of mammals and birds to become extinct over the next century. Among the species threatened with extinction are rhinos and eagles.

What would happen if the Earth had no animals?

What happens when a species becomes extinct?
When a species becomes extinct, they reduce the variety of animals, plants, or bird species from that ecosystem resulting in the extinction of the other species that were dependent on them. Different species are playing different roles in the ecosystem to maintain a balance of the world.
What animals are likely to go extinct first?
What Animals Are Likely to Go Extinct First Due to Climate Change Four animals that face increased risk of extinction as temperatures rise include Australia’s yellow-footed rock-wallaby, golden-shouldered parrot and Lumholtz tree-kangaroo, and New Zealand’s lizard-like tuatara.
What is the main cause of extinction?
We introduce new species into an area to kill a certain predator or to make sure we have fish to catch. Then the new animal takes over and many other species suffer. Pollution and climate change are the major reasons for extinction involving humans to some degree.
What is the difference between extinction and predation?
In such cases, the animals may come to extinct. Predation on the other hand refers to the process where a species is simply the food to a certain species. When the predators feed on the preys, the lives of the preys are not restored. Therefore when one is killed it means that the number is reduced.
