what supplies the energy for most of the microorganisms in the rhizosphere
Rhizosphere The food web in the rhizosphere can be considered as three different channels with two different sources of energy; the detritus-dependent channels are fungi and bacterial species and the root energy dependent channel consists of nematodes, symbiotic species, and some arthropods.[19] This food web is constantly in flux as the amount of detrius available and the rate of root sloughing changes as roots grow and age. This bacterial channel is considered to be a faster channel because of the ability of species to focus on more accessible resources in the rhizosphere and have faster regeneration times compared with the fungal channel. All three of these channels are also interrelated to the roots that form the base of the rhizosphere ecosystem and the predators, such as the nematodes and protists, that prey upon many of the same species of mircroflora.
Electron transport chain Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or, such as in the case of the oxidation of sugars, cellular respiration. In eukaryotes, an important electron transport chain is found in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation through the use of ATP synthase. It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes. In bacteria, the electron transport chain is located in their cell membrane.
