The interaction among organisms within or between overlapping niches canbe characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism.

How much energy is lost in a food chain? The energy is passed on from trophic level to trophic level and each time about 90% of the energy is lost, with some being lost as heat into the environment (an effect of respiration) and some being lost as incompletely digested food (egesta).

What is positive interaction? Positive interactions are cooperative relationships between species that result in better growth, reproduction, and survival for at least one species involved in the interaction, without negatively affecting the_other species (Morin, 1999; Stiling, 1999).

How does energy get lost in a food chain? Energy and nutrients are passed around through the food chain, when one organism eats another organism. Any energy remaining in a_dead organism is consumed by decomposers. In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.
