A series of changes in the population sizes of organisms at different trophic levels in a food chain, occurring when predators at high trophic levels indirectly promote populations of organisms at low trophic levels by keeping species at intermediate trophic levels in check. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.

These systems are comprised of a series of checks and balances between predator and prey, that tend to balance the whole. occurs indirectly between two species that are both hunted by the same predator (when one species does better, the other does worse because a predator eats indiscriminately). Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. The overall loss of energy from lower to higher trophic levels is important in setting the absolute number of trophic levels that any ecosystem can contain.

Raffaelli & Hall 1992; Schmid-Araya et al. Primary producers are usually plants and algae, which perform photosynthesis in order to manufacture their own food source. They cause inverse patterns of abundance and biomass among trophic groups. Fanfiction Ideas Generator, Ecologists study the interactions among these organisms and the factors that affect organisms' distribution. Ecological Pyramid Definition.
