Autotrophs are those organisms capable of fixing (acquiring and storing) inorganic resources in organic molecules. } . Organisms get their food in one of two ways. */ Trophic cascades like that in Yellowstone occur when predators--or the lack thereof--in an ecosystem change the abundance or alter traits of their prey, in turn affecting the next lower trophic level. { The amount of energy at each trophic level decreases as it moves through an ecosystem. Positive or negative influences of these ecological processes on diversity and the final biomasses of all groups in 2015 were assessed.
