Final answer:
The study of nutrient cycling through the environment is an example of ecology, which is the scientific study of the relationships between organisms and their environment.
Step-by-step explanation:
The study of nutrient cycling through the environment is an example of ecology. Ecology is the scientific study of the relationships between organisms and their environment. Nutrient cycling plays a crucial role in maintaining the balance of ecosystems and the health of the environment. It involves the cycling of essential elements like water, carbon, nitrogen, phosphorus, and sulfur through living organisms and the non-living environment.
