Decomposers are organisms that break down rotting trees and plants. Mushrooms, beetles and wood eaters are some of the decomposers found in a deciduous forest.Know More
Decomposers play an important role in the forest ecosystem. When a decomposer breaks down a piece of dead or decaying material, nitrogen, carbon and other nutrients seep back into the soil. The recycled nutrients serve as a source of nourishment for new trees and plants.
Unlike plants, mushrooms are unable to produce their own food, so they use enzymes to decompose dead plants and absorb needed nutrients. The earthworm is another common decomposer found in the deciduous forest. After an earthworm absorbs the nutrients it needs, it excretes castings that are rich in potash, phosphorus and nitrogen.
Decomposers are a vital component of the nitrogen cycle, which transforms an unusable form of nitrogen into the fixed form organisms need to survive. During this cycle, decomposers convert nitrogen into ammonia, allowing the nitrogen cycle to continue.
Some decomposers break down material very quickly, while others take several months or years to do their jobs. Shelf fungus, for example, decomposes trees very slowly. Eventually, a tree covered with shelf fungus falls apart. The dirt inside helps nourish new plants and trees.Learn more about Cells
Cell metabolism involves several complex biochemical reactions that occur in living organisms to maintain a normal life. These metabolic pathways are broadly classified as anabolism and catabolism.Full Answer >
Arizona State University states that meiosis is how sexually reproducing organisms, including humans, produce gametes, or sex cells. Gametes are fundamentally different from the body, or somatic, cells of sexually reproductive organisms because gametes only have half of the genetic code in their nucleus. When two different gametes fuse and produce a zygote, their half-complements of genetic material combine to form a complete genome with the full complement of chromosomes.Full Answer >
Cells are called the building blocks of life because they are the basic unit for all living organisms, and must be present for life to exist. Plants and animals have trillions of cells, while protists have only one cell, yet protists are still considered to be living organisms.Full Answer >
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.Full Answer >
