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?

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_forwardWhich three organs or tissues are the primary effector organs determining the amounts and directions of interconversions in the nutrient pools?arrow_forward
