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.
An example that shows how organisms are dependent on each other would using a food chain as an example.
• mouse eat grass and drink water ( which is nonliving)
• mouse gets eaten by fox
• then fox then eaten by coyote and the cycle continues
However is one of these organisms have low population it will be difficult for the others. For example if there is a low population of coyotes then the fox population over populate same goes for if fox are low in population then the mouses become over populated hence diseases could spread from the mouses. The organisms must keep each other in check
