It is seen in the number of species in an ecosystem or on the entire Earth. Biodiversity gets used as a measure of the health of biological systems, and to see if there is a danger that too many species become extinct. triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024447972 2020-12-16 15:52:07 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024447972 triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024464353 2020-12-16 15:55:33 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024464353 An endangered species is a group (population) of plants, animals or other organisms that is in danger of becoming extinct. This could happen because there are few of that animal left, its predators have grown in number, or the climate that it lives in is changing, or the places it lives in have been destroyed. triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024480024 2020-12-16 15:58:07 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024480024 Extinction is one of the major features of evolution. A species is extinct when no members of the species are still alive. All species become extinct sooner or later. The end of a species may happen for many reasons. It may be caused by habitat loss or by being overhunted, or by a major extinction event. An example of an animal that is now extinct is the Dodo, from over-hunting. triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024486959 2020-12-16 15:59:37 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024486959 A keystone species is a species which has a big effect on its environment relative to its numbers. The ecosystem depends on them, and would be much changed if they were not there. This is because they affect many other organisms in the ecosystem. They affect the types and numbers of other species in the community. Some sea stars prey on sea urchins, mussels, and other shellfish that have no other natural predators. If the sea star is removed from the ecosystem, the mussel population explodes uncontrollably. This drives out most other species. The urchin population grows likewise, and destroys coral reefs. Living coral reefs are the habitat for many hundreds of other species. Some other examples of keystone species are the sea otter, horseshoe crab, and wolves. Sea otters and kelp depend on each other. Without the sea otter, sea urchins would destroy the kelp, and much else in the ecosystem. triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024495632 2020-12-16 16:01:31 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024495632 Threatened species are any species (including animals, plants, and fungi) which might soon become extinct. triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024500736 2020-12-16 16:02:34 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024500736 triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024508296 2020-12-16 16:04:09 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1024508296 triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1028988972 2020-12-17 18:48:48 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1028988972 triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1028996025 2020-12-17 18:50:13 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1028996025 triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1029051861 2020-12-17 19:03:20 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1029051861 triggs12 https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1029057291 2020-12-17 19:04:42 UTC https://padlet.com/triggs12/1vr7aps8ccqvo2vd/wish/1029057291
