What does the term 'trophic level' refer to? The rate at which energy is transferred between levels. The energy level at which an organism feeds in an ecosystem. The complexity of an ecosystem. The biomass of an ecosystem.

Trophic efficiency is a measure of how nutrients are cycled from one trophic level to the next: the percentage of production transferred from one trophic level to the next, all of these, the number of feeding levels in an ecosystem.

Energy in an ecosystem passes from the sun, in the form of light energy, through multiple organisms in multiple forms. 22. What term is used to describe the complex set of feeding relationships that occurs among the multiple species of prey, multiple species of predator and multiple species of producer in a community? a) trophic level b) food chain c) nutrient cycling d) energy pyramid e) none of the above 23. If the amount of energy present in the primary producers is 5000J, approximately how much energy would be expected to be transferred to the secondary consumer level? a) 500J b) 50J c) 0.5J d) 0.05J e) 0.005J

18. Ecologists use the "Rule of 10" to calculate approximately how much energy is transferred from one trophic level to the next in an ecosystem. The basic concept behind this rule is that only 10% of the energy at one trophic level will be available to the next trophic level. What happens to the remaining "90%" of the energy?
