Question
Chapter 38.3, Problem 5MC
Summary Introduction
To determine:
The efficiency of energy transfer between trophic levels in food webs.
Concept Introduction:
Trophic level describes the position of each species in the food chain. The total quantity of the energy which is trapped by all the primary producers or autotrophs is termed as gross primary production. The remaining energy left by autotrophs is trapped by the consumers to eat is termed as net primary production.
