Decomposers

Decomposers eat dead things, like fallen leaves and wood, as well as dead animals and faeces. They provide an important service by acting as Earth’s cleanup crew. Fallen leaves, dead insects, and decaying organic matter would pile up everywhere if decomposers were not present. Decomposers are also important because they make major nutrients usable to an ecosphere primary producer, which are typically plants and algae. Decomposers are organisms that break down complicated organic matter into simple molecules such as water and carbon dioxide, as well as simple nitrogen, phosphorus, and calcium compounds. These kinds of constituents are materials that plants require in order to thrive. Decomposers are also important because they make major nutrients usable to an ecosphere primary producer, which are typically plants and algae. Decomposers are organisms that break down complicated organic matter into simple molecules such as water and carbon dioxide, as well as simple nitrogen, phosphorus, and calcium compounds. Others are generalists who consume a wide variety of different materials. Decomposers return nutrients to the soil or water, allowing producers to use them for growth and reproduction.In fact, the majority of decomposers are microscopic organisms, such as protozoa and bacteria. Other decomposers are large enough to be observed without the use of a microscope. They consist of fungi as well as invertebrate organisms, which are sometimes referred to as detritivores and include earthworms, termites, and millipedes.

Decomposer

Decay and scavenging are the processes by which deceased plants and animals are decomposed and disposed of. They also help to decompose the wastages (poop) produced by other lifeforms. Decomposers play a critical role in the health of any ecosystem. In the absence of these animals, plants would lack necessary nutrients and dead materials and garbage would accumulate in the ecosystem. Bacteria and fungi are two of the most important decomposers in the environment. One might doubt what all these decomposers eat in order to survive. Decomposers, on the other hand, feed on decaying organic matter.

Stages of Decomposition

There are following stages of decomposition;

Fragmentation- It’s the initial state of the decomposition process. Detritivores break down trash into tiny bits, which is referred to as fragmentation.

Leaching- Water – soluble nutrients that are inorganic in origin may be present in the broken particles. These nutrients dissolve in water, soak into the soil, then precipitate during the leaching process.

Catabolism- Catabolism is the process which is carried out by various fungal and bacterial enzymes for the conversion of detritus into simpler inorganic compounds. 

Humification- Humification is the process of a dark – colored amorphous substance called humus forming on the soil.

Mineralisation- The final phase in the process is mineralization. The decomposition of hummus to liberate inorganic nutrients is described as mineralization.

Examples Of Decomposer

A decomposer can be classified into four types: fungi, insects, earthworms, and bacteria. Fungi are the most common type of decomposer.

1.Fungi

Heterotrophs are organisms that feed on other organisms. They do not participate in photosynthesis and serve as the primary decomposers in the ecological system they inhabit. As a result, while algae serve as producers in a food chain, fungi serve as decomposers. Furthermore, because mushrooms are a filamentous fungus, they are considered to be decomposers as well.

Fungal decomposers break down litter by pre-digesting it, which means they release enzymes into the environment before the litter is fully digested and disintegrated. During the act of consuming dead materials, the fungi secrete enzymes that break down the dead matter, which is then absorbed or ingested by the fungus itself. Because fungi decompose dead matter and extract nutrients from that too, they are classified as saprotrophs, which means they feed on dead matter.

2.Insects

In the environment, insects such as flies, dung beetles, maggots, and ants contribute to the decomposition process by carrying out the task of decomposition. As decomposers, insects are distinguished from other animals by the fact that they bring out internal absorption of the waste in their intestinal. 

There are several different types of insects that are involved at the time of decomposition, which are classified depending on the type of decaying organisms that they feed on are insects feed on plant tissues that have died or decayed, 

animals that have died or insects that feed on tissue and insects that feed on excrement (eg: Arthropods like the dung beetle). 

3.Earthworms

Decomposers are microbes that feed on dead matter (both of plant and animal origin) and faecal waste through their digestive tracts, allowing the litter to decompose and decompose.Earthworms are the most well-known illustration of worms that enhance the land by decomposing the organic matter in the environment. In addition to dead matter and faecal waste, earthworms consume litter, which is treated by enzymes in their digestive tract before being expelled back into the soil by their nematode hosts. These worms nourish the soil by supplying it with critical nutrients such as phosphate and calcium, amongst other substances. Worms are important in the ecological system of the soil because they break down organic matter.

4.Bacteria

These microscopic organisms, which can be found everywhere, are the ceremonial stewards of the decomposition process. Bacteria play an important role in the recycling of essential nutrients such as nitrogen and carbon, and in making these nutrients accessible to the makers in the food web. Bacteria also are categorised as saprotrophs, which means they produce sugar.

Conclusion

Decomposers are creatures that eat on the remains of dead and decaying animals and plants. By obtaining nutrition and energy from such materials, decomposers return some nutrients to the ecological system, where they can be absorbed by plants. Biodegradable microorganisms are known as natural decomposers because they have the extraordinary ability to use a wide range of organic substances as a source of energy while also converting toxic substances into harmless by-products. Bioremediation is the process of removing toxic pollutants from the environment with the help of microbes. It is a long-term and cost-effective solution that is environmentally friendly. The development of improved tools and methods in molecular biology and genetic engineering has altered the way this natural phenomena is seen, and it has opened up new paths for further investigation into bioremediation in greater depth.
