Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi. As noted in Figure 52.15, the addition of nutrients to a lake can cause an algal bloom. Through this process, decomposers release nutrients, such as carbon and nitrogen, back into the environment. Bacteria produce chemicals such as ammonia, hydrogen sulfide, and methane, which cause strong odors. Environmentalist Types, Job & Examples | What is Environmentalist?

C., Bainbridge, B. W., Moore, P. D., & Robinson, C. H. (2006). While scientists have identified about 100,000 species of fungi, this is only a fraction of the 1.5 million species of fungus likely present on Earth. Abiotic decomposition happens when physical or chemical processes break down organic matter, like when ultraviolet radiation causes photodegradation. They are also known as friendly worms because of their ability to enrich soil by decomposition of litter. Jessie has attained two bachelor's degrees, one in History and Political Science from the University of Stellenbosch and one in Genetics and Zoology from the University of South Africa. 2013 Nov 12;4:333.

There are essentially four types of decomposers: fungi, insects, earthworms, and bacteria. Northern Hemisphere Overview & Facts | What is the Northern Hemisphere? Decomposers include bacteria, fungi, earthworms, millipedes and insect larvae. Bacteria are single-celled microscopic organisms. Ernest Rutherford Experiments & Discoveries | Who was Ernest Rutherford? "Importance and Roles of Decomposers. Decomposers are two major groups, including detritivores and saprotrophs. Seamount Overview & Formation | What is a Seamount? Decomposition is the process of breaking down the complex organic matter into simpler substances. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. Animal decomposition can be divided into five stages. pKa: Acid Strength Formula & Examples | What is pKa in Chemistry? For example, animal urine is broken down into nitrogen by nitrifying bacteria to be used in the soil by plants. Privacy Policy. There are a number of things that affect how fast things break down. Animal decomposition differs from plant decomposition in the rate of decomposition as well as the microorganisms attracted due to different chemical structures and immune system differences. Soybean Plants: Forms & Uses | What is Soy? Pelvic Girdle Anatomy & Bones | What is the Function of Pelvic Girdle?

Decomposers do not need to digest organic material internally in order to break it down; instead, they can break down matter through biochemical reactions. When an organism dies and decomposers do the work of decomposition, the organism's remains go through five stages of decomposition: fresh, bloat, active decay, advanced decay, and dry/remains. (iii) If decomposers are absent, this process will not take place and the Earth will see dead bodies everywhere, thus increasing garbage.
