Chapter 42.3, Problem 1CC
If an insect that eats plant seeds containing 100 J of energy uses 30 J of that energy for respiration and excretes 50 J in its feces, what is the insect’s net secondary production? What is its production efficiency?

Look at figure 1 in the passage. 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.
What is the carnivore diet and what does it entail? What are the goals of this diet? Who would benefit from this diet? Does this diet need to be modified for an athlete versus a sedentary individual? If so, why and how?
