Many species of organisms are endangered today.
Currently, there are more than 150,300 species on The IUCN Red List, with more than 42,100 species threatened with extinction, including 41% of amphibians, 37% of sharks and rays, 36% of reef building corals, 34% of conifers, 27% of mammals and 13% of birds.
[CER] Is global warming real and is it causing species to go extinct today?

During this lesson you will learn more about how the environment influences populations of organisms over multiple generations.
✎Notes:
- Changes in an organism’s habitat are sometimes beneficial to it and sometimes harmful.
- For any particular environment, some kinds of organisms survive well, some survive less well, and some cannot survive at all.

Coral reefs are one of Earth’s most diverse habitats. There are many different kinds of animals and plants making their living on a coral reef. Reefs lie along coasts of many tropical locations. They need certain environmental factors to survive, which warm coastlines can provide. They need a salty, warm environment (between 68° and 82° F). This keeps the reefs healthy and thriving. They need areas that are constantly churned by the waves to shower them with bits of food over and over. The waves also stir up oxygen over the reefs that the animals there need. The waves keep sand from building up on the coral anchored there. Coral are animals and cannot survive if they are buried in sand.

Coral reefs have a partnership with an alga called zooxanthellae that lives in the coral tissue itself. Zooxanthellae alga provides food and oxygen to the coral while taking up the carbon dioxide that the coral releases. The coral provides the algae with a safe place to live and grow. Zooxanthellae alga gives coral its many pretty colors. Zooxanthellae alga is very sensitive to pollution or the water temperature changes. It will die and the coral loses its pretty colors. This is called coral bleaching. It is a sign of an unhealthy coral reef.

/ ViI / NExt Level (✓) Checklist:
- Can you make a claim that can be supported about organisms in a particular habitat?
- Can you describe your evidence necessary to support your claim?
- Can you evaluate your evidence to determine whether it is relevant and supports your claim?
- Can you use reasoning to construct an argument, connecting the relevant and appropriate evidence to the claim, including describing that any particular environment meets different organisms' needs to different degrees due to the characteristics of that environment and the needs of the organisms?
