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
Cells need oxygen for the efficient use of glucose in cellular respiration, the main method most organisms use to gain energy. The oxygen bonds to portions of the glucose molecule, releasing water, carbon dioxide and a large amount of energy. The cells then use that energy to generate adenosine triphosphate, commonly abbreviated as ATP, the main energy currency used by the cell.Full Answer >
Osmoregulation is an important process in both plants and animals as it allows organisms to maintain a balance between water and minerals at the cellular level despite changes in the external environment. Osmoregulators take up both minerals and water from the environment and have methods of expelling what they do not need and conserving what is in short supply.Full Answer >
The cellular basis of life is called the cell theory, which states that the cell is the basic functional unit of all living organisms. The cell theory also states that the activity of an organism depends on its cells and that reproduction has a cellular basis.Full Answer >
Cells are important for living organisms because cells are the basic building blocks from which all organisms are created. While some organisms are comprised of a single cell, others are multicellular entities with different cell types.Full Answer >
