The correct answer is electrons.
Electron transport chain refers to an array of complexes, which mediates electrons from electron donors to electron acceptors through redox reactions, and combines the transfer of electrons with the transfer of protons through a membrane.
This produces an electrochemical proton gradient, which instigates the production of ATP. The ultimate electron acceptor in the electron transport chain is oxygen in aerobic respiration and sulfate in anaerobic respiration.
<span>When organisms are born in the wild, they tend to start developing an understanding of their surroundings based on their experiences. If an organism is transplanted to a different environment right after birth, it will develop the instincts to survive in that environment. A sudden change in its environment will result in the organism being out to place, possibly unable to cope with the selection pressures of its new environment. This will likely be the case with these guppies. This issue with transplantation is very real with animals born in captivity, which is why many are put through simulation exercises such as hunting and hearing the calls of predators, so that they may be able to survive in the wild, when transferred.</span>
Answer: food chains or webs
In an ecosystem, energy from the sun is transferred by the way of food chains or webs. A food chain is a linear sequence of organisms through which food and energy is passed as one organism eats the another. A food web is the interconnection or relation of food chains. In a food chain energy is distributed among the trophic levels. Plants are primary producers which traps energy from sun for photosynthesis and belong to first trophic level in the food chain. The energy of sun present in plants is transferred to subsequent higher trophic levels when plants are consumed by other organisms.
