Question

Briefly describe three aspects of nutrient cycles.

✓

Answer

Three main aspects of nutrient cycles are:
1.Production & Uptake – Plants absorb nutrients (like carbon, nitrogen, phosphorus) from soil, water and air to make food.
2.Transfer through Food Chain – Nutrients pass from plants to herbivores, then to carnivores and other organisms.
3.Decomposition & Recycling – When plants and animals die, decomposers break down their remains and release nutrients back to soil, water and atmosphere for reuse.
