A more thorough explanation:

Definition: An endangered species is a type of plant or animal that is at risk of becoming extinct. This means that there are very few of them left in the world, and if we don't take action to protect them, they could disappear forever.

Examples: Some examples of endangered species include:

• The giant panda, which is native to China and has a population of less than 2,000 in the wild.
• The black rhinoceros, which is found in Africa and has a population of less than 5,000.
• The leatherback sea turtle, which is found in oceans around the world and has a population of less than 34,000.

These examples illustrate the definition of endangered species because they are all types of plants or animals that are in danger of disappearing from the world. Their populations are very small, and if we don't take steps to protect them, they could become extinct. This would be a great loss to the world, as each species plays an important role in the ecosystem.
