Textbook Question
Chapter 56, Problem 1S
Given that ectotherms do not utilize a large fraction of ingested food energy to maintain a high and constant body temperature (generate heat), how would you expect the food chains of systems dominated by ectothermic herbivores and carnivores to compare with systems dominated by endothermic herbivores and carnivores?

Increased temperature causes more solar radiation to enter the atmosphere thereby further increasing temperature. d. Increased CO2 causes the oceans to become more acidic which causes oceanic volcanoes to erupt releasing more CO2 into the environment. e. Burning fossil fuels releases CO2, which traps long-wave radiation causing temperatures to increase.arrow_forward
