Recycling of Matter

Where do decomposers recycle the nutrients from dead plant and animal matter?

• In terrestrial and aquatic environments, the nutrients are eaten by consumers.

• In terrestrial environments, the nutrients are absorbed by the decomposers. In aquatic environments, the nutrients are recycled back to the water.

• In terrestrial environments, the nutrients are recycled to the soil where plants can reabsorb them. In aquatic environments, the nutrients are absorbed by the decomposers.

• In terrestrial environments, the nutrients are recycled to the soil where plants can reabsorb them. In aquatic environments, the nutrients are recycled back to the water.

A diagram is provided. Identify an energy path starting with a producer and ending with bacteria or fungi recycling the nutrients from dead plant or animal matter back to the soil of the environment.

• Grasses (producer) → Monkey (first-level consumer) → Mongoose (third-level consumer) → Hyena (fourth-level consumer) → Bacteria and Fungi (Decomposers)

• Grasses (producer) → Termite (first-level consumer) → Impala (third-level consumer) → Hyena (fourth-level consumer) → Bacteria and Fungi (Decomposers)

• Grasses (producer) → Mouse (first-level consumer) → Mongoose (third-level consumer) → Hyena (fourth-level consumer) → Bacteria and Fungi (Decomposers)

• Grasses (producer) → Mouse (first-level consumer) → Eagle (third-level consumer) → Hyena (fourth-level consumer) → Bacteria and Fungi (Decomposers)

When animals break down glucose to create energy, they release water and carbon dioxide (CO2.) How can carbon dioxide (CO2) be reused within the food web?

• It can be used by animals as a source of oxygen.

• It can be used by both plants and animals to produce energy.

• It can be used by plants during photosynthesis to create glucose.
