A keystone species refers to the organisms that define the entire ecosystem. These organisms are important because without them the ecosystem will work differently. They are known to be low in functional redundancy that means if these so-called keystone species disappear, there are no other species who can fill in their role. We can protect them by preserving and protecting their natural habitat, avoiding hunting activities especially the organisms that are considered to be critically endangered, planting trees, and proper waste disposal. These are some of the activities that we can do to protect them.
