Select all the decomposers from the list below.

Complete the diagram with the matter exchanged between producers and consumers during photosynthesis and respiration.

How do producers, consumers, and decomposers work together in a garden ecosystem?

Producers create energy from sunlight, consumers eat producers, and decomposers break down dead organisms to recycle nutrients.

Producers eat consumers, decomposers create energy from sunlight, and consumers break down dead organisms.

Decomposers create energy from sunlight, producers eat consumers, and consumers recycle nutrients.

Consumers create energy from sunlight, decomposers eat producers, and producers break down dead organisms.

Match the term with its definition.

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