Dear student
1. An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, and invasive species.
2. An ecosystem can be described simply as the collection of all living and non-living components in a particular area. The living components of the environment are known as biotic factors and non-livings are called abiotic factors.
