Final answer:
The statement is True; plants help prevent soil erosion and enhance soil quality through their roots during life and release nutrients on decomposition.
Step-by-step explanation:
The statement that plants help prevent soil erosion and also improve soil quality when they decompose is True. Plants play a critical role in maintaining soil structure and fertility. Their roots help bind soil together, reducing the impact of wind and water which can cause erosion. In addition, when plants die and decompose, they release nutrients back into the soil, improving its quality and fertility for other plants.
Alternative agricultural practices, such as minimal tillage or no tillage methods, limit soil compaction, protect soil organisms, reduce costs, promote water infiltration, and assist in preventing topsoil erosion. These practices are part of a sustainable approach to farming, contributing to soil conservation and mitigating the effects of global warming.
Thus, the decomposition of plants, the activity of microorganisms, and the use of no-till farming methods collectively enhance soil health, demonstrating the critical role of vegetation and responsible agricultural practices in ecosystem sustainability.
