Question
-Assume that humans are the second-level carnivores and that
each energy unit in their level represents 25 people. How many people can be supported in the ecosystem?
-Assume that we eat herbivores only. As first-level carnivores, how many humans can now be supported in the ecosystem?
-If we ate plants only, how many human could be supported by the ecosystem?
-If we ate plants only, what would happen to the amounts of energy available for the other herbivores and carnivores in the ecosystem?
-Let's look at energy conversion another way. It takes about 0.5 kg of meat to support a human for one day. Assuming that beef is the only available nutrient, how much meat energy (kilograms of meat) will it take to get you to 20 years old?
-How much plant energy (kilograms of plant) will it take to feed the beef that gets you to 20 years old? (Refer to question #5.)
-Your digestive system is very efficient at digesting meat, but is not as efficient at getting all of the available nutrition from plants. Assumes that you were raised on plants instead of emat. Plant material has about 40% of the per-kg food value as meat. How much plant energy would it take to get you to 20 years old?
