microcosm

The correct answer is C. Microcosm

Explanation:

In biology and ecology, one of the techniques used to study ecosystem is the creation of artificial ecosystem or models of ecosystems that can be placed indoor in a laboratory or outdoor and are called microcosms, as they represent a larger and more complex ecosystem. Microcosms are considered as one important technique to study natural processes because they allow testing in a controlled way and without having effects on the real macro ecosystem. Therefore, a re-created ecosystem in a laboratory environment is a microcosm.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
