검증된 단계별 안내1
Understand the concept of nutrient cycling: In an ecosystem, nutrients are recycled through various processes such as decomposition, absorption by plants, and consumption by animals.
Recognize the role of decomposers: Decomposers like bacteria and fungi break down dead organic matter, releasing nutrients back into the soil, which plants can then absorb.
Identify the movement of nutrients: Nutrients move through the food chain as plants are consumed by herbivores, which are then consumed by carnivores.
Acknowledge the return of nutrients: When organisms excrete waste or die, decomposers break down the organic material, returning nutrients to the soil, completing the cycle.
Conclude that nutrients cycle: Based on the above steps, nutrients do indeed cycle through an ecosystem, as they are reused and recycled continuously.
