Name the forms of water in which it exists in the soil.

Explanation

To answer the question about the forms of water in which it exists in the soil, we can identify three main types:

1. **Gravitational Water**: This is the water that moves through the soil due to the force of gravity. It is considered free-moving water that drains through the soil and is not retained. This type of water is typically found in excess after heavy rainfall and can move quickly through the soil layers.

2. **Hygroscopic Water**: This type of water is present in very small amounts and forms a thin film around soil particles. Hygroscopic water is tightly bound to the soil and is not available for plant uptake. Plants cannot absorb this water because it is held too tightly by the soil particles.

3. **Capillary Water**: This water occupies the small pores in the soil and is held against the force of gravity. Capillary water is available for plants to absorb as it can move through the soil via capillary action. This is the water that plants primarily utilize for their physiological processes.
