In most terrestrial ecosystems, forests store the most nutrients in biomass. Forests consist of trees, shrubs, understory plants, and various microorganisms that collectively accumulate a substantial amount of nutrients, such as carbon, nitrogen, phosphorus, and others.

The group of organisms essential for recycling nutrients in the ecosystem are decomposers. Decomposers include various microorganisms (e.g., bacteria and fungi) and macroscopic organisms (e.g., detritivores like earthworms, termites, and some insects). Their primary role is to break down dead organic matter, such as fallen leaves, dead plants, and animal carcasses, into simpler inorganic compounds. This decomposition process releases essential nutrients back into the soil, making them available for uptake by plants and other organisms, thus completing the nutrient cycle in the ecosystem.

Without decomposers, nutrients would remain locked in dead organic matter, limiting their availability for living organisms, and the ecosystem would struggle to sustain life over time. Hence, decomposers play a crucial role in nutrient recycling, maintaining the balance and functioning of the ecosystem.

Nutrient cycling in forest ecosystems these nutrients are stored in the leaves, flowers and other parts of plants. The nutrients are either transferred to animals when animals eat the plants or they are transferred back into the soil. Nutrients are fairly evenly shared between the stores; however, the biomass is the largest store due to a large number of trees. The soil nutrient store is quite large due to the input of nutrients from the weathered rock below the surface combined with nutrients transferred from the litter layer through decomposition. An energy pyramid, also known as a trophic or ecological pyramid, is a graphical representation of the energy found within the trophic levels of an ecosystem. The bottom and largest level of the pyramid is the producers and contains the largest amount of energy.The trophic level that contains the greatest biomass in most ecosystems is the producers. Producers are organisms that are able to make their own food from sunlight or chemicals. Since the source of energy is the sun, the trophic level representing producers (plants) contains the most energy. The base of the trophic pyramid is the source of energy for all consumers. The amount of energy decreases at each tropic level as you go up the pyramid. Decomposers in ecosystems act as environmental cleaners by decaying dead plants and animals. They aid in the recycling of nutrients. They make room for a new life in the biosphere by decaying the dead. Nature has its own recycling system: a group of organisms called decomposers. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth's cleanup crew. Decomposers in ecosystems act as environmental cleaners by decaying dead plants and animals. They aid in the recycling of nutrients. They make room for a new life in the biosphere by decaying the dead. The soil ecosystem is extremely important. Terrestrial plants obtain their water and much of the nutrients they need from the soil, absorbing them through their roots. Soil also provides habitat for a great diversity of animals and microorganisms that play a crucial role in litter decomposition and nutrient cycling. Bacteria, fungi, insects, earthworms, bugs, and other creatures dig and digest the compost into fertile soil. The minerals and nutrients in the soil are recycled back into the production of crops. Decomposers play a vital role in keeping the food chain functioning properly. As decomposers break down the remains of dead organisms and produce waste, nutrients are recycled back into the soil for producers to absorb through their roots. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
