Final answer:
Nitrogen is often the least available nutrient in terrestrial environments and is a limiting factor in plant growth. Other nutrients like phosphorus, potassium, and magnesium are also recycled within ecosystems and are important for sustaining life in terrestrial environments.
Step-by-step explanation:
Nitrogen is often the least available nutrient in terrestrial environments. In most terrestrial ecosystems, nitrogen is a limiting factor in plant growth.
Other nutrients that are recycled within ecosystems include phosphorus, potassium, and magnesium. These nutrient cycles are essential for the sustainability of life in all natural terrestrial ecosystems.
