Compost is the decaying organic substance that enriches topsoil with nutrients essential for plant growth. It is created by mixing organic waste such as food scraps, yard clippings, and manure, allowing it to break down into a nutrient-rich soil amendment.
They are called saprophytic fungi, which decompose and absorb nutrients from dead organic matter in their environment. This process is essential for nutrient recycling in ecosystems.
The main source of soil organic matter is decaying plant and animal material. Organic matter plays a crucial role in the soil by improving its structure, water-holding capacity, nutrient availability, and overall fertility. It also enhances microbial activity, which is essential for nutrient cycling and overall soil health.
Decaying organic matter refers to plant or animal material that is in the process of breaking down and decomposing. This process is carried out by microorganisms like bacteria and fungi, which feed on the organic material and break it down into simpler substances. Decaying organic matter plays a critical role in nutrient cycling and soil fertility in ecosystems.
Fungi obtain energy and nutrients by absorbing them from their surroundings. They can derive nutrients from living or dead organic matter, such as plants, animals, and decaying material in the environment. This ability to break down and decompose organic material is essential for nutrient cycling in ecosystems.
The main source of organic material in soil is decaying plant and animal matter. This organic material undergoes decomposition by microorganisms, releasing nutrients that are essential for plant growth. Additionally, organic material helps improve soil structure, water retention, and nutrient availability.

Total organic matter in an ecosystem can vary greatly depending on the ecosystem type and location. It includes living organisms (plants, animals, microorganisms) as well as decaying organic material like dead plant matter and soil organic matter. The total organic matter is essential for nutrient cycling, energy flow, and ecosystem functioning.
Yes, a plant is an organic substance because it is made up of organic compounds such as carbohydrates, proteins, lipids, and nucleic acids essential for their growth and development.
Zygomycota fungi can be found in various environments such as soil, decaying organic matter, and animal feces. They play an important role in breaking down organic material and nutrient cycling in ecosystems.
