A microbial population ingests 100 Kcal/m^2 of food materials each year. Its assimilation efficiency is 50% and its respiration efficiency is 30%. How much energy is used for secondary production each year.?
Homework Answers
Secondary production refers to the energy used in the consumers food to create its own biomass. Assimilation is total energy taken in and used for growth, reproduction and respiration. Production efficiency is fraction that is not used for respiration. Assimilation -respiration = production efficiency.(50-30=20% from data.)
(20*100)/100=20 Kcal/m^2 energy is used for secondary production each year...

Problem 2: Pedal Power
Many villages in the developing world lack access to electricity.
One proposed solution is the ‘Free Electric’ bicycle, which is a
stationary bike hooked up to a generator and battery. Pedaling the
bike powers the generator, which creates electricity that is stored
in the battery. The inventor claims that 1 hour on the bike can
produce a whole day of electricity. Let’s put it to the test!
Assume the...

6) (a) The United States, with a population of 2.2×10^8 people, consumes 5×10^19 J per year. What is the per capita consumption in watts? (b) The sun's radiation provides the earth with 1000 W/m^2. Assuming solar energy can be converted to electrical energy with a 20% efficiency, how much area is needed to serve the energy needs of each U.S. citizen?

CSM Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $433,000 is estimated to result in $163.000 in annual pretax cost savings. The press is eligible for 100 percent bonus depreciation and it will have a salvage value at the end of the project of $64,000. The press also requires an initial investment in spare parts inventory of $16,900, along with an additional $3,900 in inventory for each succeeding year of...

despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)

Each year Emperor penguins migrate across Antarctica to their breeding grounds 50 miles away from the sea (and food). For over 2 months the male emperor penguins care for and incubate the eggs while the females return to the sea to feed. During this time, the male penguin can lose up to 50% of its biomass (by dry weight). Where did the majority of this biomass go? Select one or more: A. The mass was converted to urine and feces...
