Final answer:
The question is confused with the Canadian Model of Occupational Performance (CMOP); instead, it refers to ecosystems. There are three broad categories of ecosystems: freshwater, marine, and terrestrial. These categories have subdivisions based on specific environmental habitats and organisms.
Step-by-step explanation:
The student is asking about the types of environments as categorized by the Canadian Model of Occupational Performance (CMOP), which is actually about occupational therapy and not ecosystems. However, since there seems to be a confusion, I will clarify about ecosystems. There are three broad categories of ecosystems based on their general environment: freshwater, marine (or ocean water), and terrestrial. These broad categories are further subdivided into individual ecosystem types, each characterized by a specific environmental habitat and the organisms that are present within it.
