What term describes the absorption of nutrients by plants from the soil?

The term that describes the absorption of nutrients by plants from the soil is "Nutrient Uptake." This process involves the roots of plants taking in essential nutrients and minerals from the soil solution, which are necessary for growth and development. Nutrient uptake is critical for plants as it directly affects their health, productivity, and ability to thrive in their environment.

The other terms do not accurately define this specific process. "Nutrient Cycle" refers to the natural process by which nutrients are recycled in the ecosystem, involving various steps such as decomposition and nutrient release back into the soil. "Nutrient Transfer" generally denotes the movement of nutrients from one location to another, rather than the specific process of plants absorbing them. "Nutrient Sourcing" might imply the identification of sources of nutrients but does not pinpoint the actual uptake process by which plants acquire these nutrients from the soil.
