Question
13) Which of the following (one and only one correct) is true of energy relationships between trophic levels The amount ofenergy flowing through one trophic level is 10% of that flowing through the next a. lower trophic level b. The amount of energy flowing through one trophic level is 10% of that flowing through the next higher trophic level c. The amount of energy flowing through one trophic level is always greater than that flowing through the next lower trophic level d. The amount of energy flowing through one trophic level is always less than that flowing through the next lower trophic level e. The amount of energy flowing through one trophic level is greater or less than that flowing through the next lower trophic level, depending on the specific species comprising the ecosystem. 14) Which of the following (one and only one correct) is true of biomass between trophic levels: a· The biomass of one trophic level is 10% of that of the next lower trophic level b- The biomass ofone trophic level is 10% of that of the next higher trophic level The biomass of one trophic level is always greater than that of the next lower trophic level The biomass of one trophic level is always less than that of the next lower trophic level The biomass of one trophic level is greater or less than that of the next lower trophic level, depending on the specific species comprising the ecosystem. c. d. e. 15) Which of the following is the correct order for ease (higher rate) of decomposition of different plant compounds (ordered from fast rate to slowest): a. Lignin>Sugars>Proteins> Cellulose; b. Sugars> Lignin Cellulose> Proteins c. Cellulose> Sugars>Lignin> Proteins d. Lignin Cellulose>Proteins>Sugars; e. Sugars>Proteins> Cellulose> LigninExplanation / Answer
The true statement about the energy relationship between tropic levels is that the amount of energy flowing through one tropic level is 10% of that flowing through the next lower tropic level (10%law).
Upright pyramid of energy.
The correct statement about the biomass between the two tropic levels is that the amount of biomass in a tropic level is always less than that of next lower tropic levell.
The order of rate of decomposition from faster to slower r is the following,
Sugars > protein >cellulose > lignin
Sugars and the protein are decomposed at a faster rate because of being soluble.
Cellulose and lignin are decomposed slowly because of bsing insoluble.
