If an insect that eats plant seeds containing 100 J ofenergy uses 30 J of that energy for respiration andexcretes 50 J in its feces, what is the insect’s net secondary production? What is its production efficiency?
A bird eats sunflower seeds from a bird feeder on a snowy day. Of the 1000 J of energy that was in the consumed seeds, the bird stored 10 J of energy in its body, eliminated 150 J of energy in its waste, and used the remaining energy to respire. What is the production efficiency of this bird?
Useful equation: PE = Pn/An x 100
Is feed cost an important part in animal production?
Why or why not?

Which of the following relationships is BEST shown by the data? The more massive the penguin, the more food is delivered to the offspring. The maximum efficiency in food foraging is reached at about 20% sea ice concentration. The amount of food delivered is about the same at 12% and 15% sea ice concentration. The greater the sea ice concentration, the greater the efficiency in delivering food.arrow_forwardIf only a fraction of the energy that the herbivore gets from plant food becomes part of the herbivore’s body, what happens to the rest of it?arrow_forward
