Match the term with its definition.

Draggable item		Corresponding Item
Carbon dioxide		Organisms that break down decaying matter
Nutrients		Substances needed to grow
Organic matter		Gas humans inhale
Decomposers		Gas humans exhale
Oxygen		Animal waste and decaying organisms

Here's a simplified overview:
Animal Waste Production: Animals produce waste, which includes feces, urine, and other organic materials.
Decomposition by Fungi: Fungi, along with bacteria, play a crucial role in breaking down these organic materials. They secrete enzymes that break down complex organic compounds into simpler substances.
Nutrient Release: As fungi decompose the waste, they release nutrients such as nitrogen, phosphorus, and carbon back into the soil.
Nutrient Uptake: Plants absorb these nutrients from the soil, which helps them grow. These plants may then be consumed by animals, continuing the cycle.
This process is essential for nutrient cycling in ecosystems, ensuring that organic matter is recycled and made available for other organisms. 🌱
