Collapse of intermediate trophic levels in 'wasp-waist' systems causes:

“Drastic changes at higher and lower levels” for collapse of intermediate trophic levels in 'wasp-waist' systems causes. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Ecosystem processes are constrained by energy conservation and by the cycling of matter. Energy enters mainly through primary production, is lost as metabolic heat at every transfer, and therefore cannot be recycled in the way that carbon, nitrogen, phosphorus, or water can. The remaining alternatives—“No impact”, “Increased predat

Controls Ecosystem

Collapse of intermediate trophic level species mainly causes:

“Drastic ecosystem changes at both higher and lower trophic levels” for collapse of intermediate trophic level species mainly causes. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Ecosystem processes are constrained by energy conservation and by the cycling of matter. Energy enters mainly through primary production, is lost as metabolic heat at every transfer, and therefore cannot be recycled in the way that carbon, nitrogen, phosphorus, or water can. The remaining alternatives—“Stability in all
