Answer:
C. ecosystem
Explanation of why the others are incorrect:
A. Community: Community refers to the assemblage of different species that interact and live in the same geographic area or habitat. It does not encompass all the different habitats, biological communities, and ecological processes, as mentioned in the question.
B. Genetic: Genetic biodiversity refers to the variety of genetic information within a particular species. It focuses on the genetic variation and diversity among individuals within a species, and does not encompass all the different habitats, biological communities, and ecological processes.
D. Species: Species biodiversity refers to the variety of different species present in a particular area or ecosystem. It focuses on the diversity of species and does not encompass all the different habitats, biological communities, and ecological processes.
In contrast, C. Ecosystem encompasses all the different habitats, biological communities, and ecological processes, including the interactions between living organisms (community), genetic diversity within species (genetic), and the variety of different species present (species). Ecosystem refers to the broader ecological context that encompasses all the living and non-living components of a particular environment or area, and how they interact with each other.
