Endangered Species - Definition & List of Endangered Species
An endangered species can be a plant, an animal, or any other type of organism that is threatened by extinction. The International Union for Conservation of Nature (IUCN) keeps a Red list of threatened species. This red list is a guide that defines the specific reason and severity of the extinction of the species. Species can be listed as endangere

Quite a few species of plants and animals are endangered in India. Why?
Species in India are facing a high risk of extinction known as endangered species and some endangered flora include the ebony tree, umbrella tree, etc., and a few endangered faunas include one-horned rhinos and Asiatic lion etc. The high risk of being endangered in India is because of the exploitation of plants and animal resources and also other d

Keystone Species and Their Role in Ecosystem
Keystone species are those that are unique and essential to the functioning of an ecosystem. Keystone species research provides essential theory and evidence for conservation ecology, biodiversity, habitat management, and the dynamics and stability of the ecosystem. Their daily actions have a direct or indirect impact on a wide range of other speci

Egestion in Simple and Complex Species
Egestion is the final step of digestion. It is a process of removing waste material from an organism. For simple species, egestion happens when cell vacuoles collect unwanted food and materials from the cells. After that, they fuse it with the cell membrane. The cell membrane then breaks down and the waste materials are released outside of the body

Extinction of Species
Extinction of Species: As per the definition, “Extinction is the process of evolution that leads to the disappearance of a population or species.” In simpler words, Extinction is the death of all members of a species of plants, animals, or other organisms. In this article, we will study in depth the Extinction of Species. We will take a look at a l

Can a community contain two populations of the same species?
No, a community can't contain multiple populations of the same species. In ecology, a community refers to a group of interacting species inhabiting the same area and sharing resources. Within a community, different populations of the same species may occupy distinct niches or habitats, leading to spatial segregation or resource partitioning. For ex
