One common interaction between biotic and abiotic components of an ecosystem is photosynthesis. Sunlight is abiotic (solely energy), and it fuels the synthesis of sugars and proteins inside plant cells once it is taken up by plant leaves.Continue Reading
A square meter of land on Earth can receive a maximum of just over 1 kilowatt of sunlight. This energy is available to plants for uptake through its green tissues, primarily leaves. Once absorbed, the sun's energy is used by special organelles, called chloroplasts, to synthesize organic molecules with high potential energy. These molecules are then transported throughout the plant's tissues and used to drive the production of the plant's tissues. In the process, the plant excretes oxygen, which is also an abiotic input that can be taken up by animals for their own use.
Photosynthesis requires more than just sunlight. Another abiotic component of plants' metabolism is carbon dioxide, which is taken up by plants through small openings in their leaves called stoma. Water is also an important abiotic component of photosynthesis. Water is used by chloroplasts as a solvent and as an ingredient in the construction of sugars. Once synthesized, these sugars are available for use by the rest of the ecosystem via consumption by herbivores.Learn more about Biology
ELISA, or enzyme-linked immunosorbent assay, measures the concentration of a factor called an analyte by attaching enzyme-linked antibodies to plastic plates via a substrate and observing their interaction with an antigen during incubation. The ELISA differs from other antibody assays in that by fixing the antibodies, it is possible to measure the analyte concentration. The analyte's presence and quantity indicate the presence or absence of the antigen.Full Answer >
Phenotype is an organism's observable properties that are the result of the interaction of the organism's genotype and the environment. Observable properties include things such as eye color, height and hair color.Full Answer >
ATP synthesis is the formation of adenosine triphosphate through the interaction of the ATP synthase enzyme with cellular material. The ATP synthase enzyme binds adenosine biphosphate with inorganic phosphate to produce ATP. ATP is the basic unit of energy that enables the cells of most living organisms to function.Full Answer >
Decomposers are organisms that break down waste (such as fecal matter) and dead animals and plants in an ecosystem. Fungi, bacteria and scavengers are examples of different decomposers.Full Answer >
