Examples
-
Trophic interactions of tundra and subarctic forest plant-based food webs are centered on a few dominant animal species, which often have cyclic population fluctuations that lead to extremely high peak abundances in some years.
-
Trophic interactions with either the mountain birch host or its insect parasitoids are the most plausible mechanisms generating cyclic outbreaks in Epirrita.
-
One contributing factor is that predators often control populations of herbivores so that herbivores do not dominate the landscape and cannot eliminate all the plants (See Predation; Trophic cascade).

Trophic interactions in Arctic ecosystems and the occurrence of a terrestrial trophic cascade.
-
Trophic interactions are likely to be affected by climate change.
-
Trophic-level structure is simpler in the Arctic than further south.
-
Trophic structure is less complex in the Arctic than further south.
-
Trophic cascades are now known from a wide range of marine, freshwater, and terrestrial ecosystems.

Trophic interactions are also described in more detailed form as a food chain, which organizes specific organisms by their trophic distance from primary producers, and by food webs, which detail the feeding interactions among all organisms in an ecosystem.
