What is nutrient cycling in nature?

Explanation

### Step-by-Step Solution:

1. **Definition of Nutrient Cycling**: Nutrient cycling refers to the cyclic movement of nutrients through various components of the ecosystem, including both biotic (living organisms) and abiotic (non-living elements) factors.

2. **Movement of Nutrients**: Nutrients do not remain stationary; they move from abiotic components (like soil, water, and air) to biotic components (like plants, animals, and microorganisms).

3. **Role of Energy**: The movement of nutrients requires energy. This energy is primarily derived from the sun, which supports the process of photosynthesis in plants.
