Chapter 54, Problem 8TYK
Summary Introduction
Introduction:
In an ecosystem, the transfer of energy decreases from one trophic to the next trophic level. Ecological efficiency is the efficiency with which energy is transferred. It is determined by efficiencies of different processes, like harvesting food, assimilating ingested energy, and production of new biomass.

- Which of the following is an endotherm? a. a shark b. a frog c. a monkey d. a snakearrow_forwardBirds and mammals are endotherms. They maintain body temperature by producing heat through metabolism. Endothermy is energetically expensive for an organism, yet endotherms have become the dominant group of tetrapods. What is a major evolutionary advantage of endothermy? A. Endothermy allows greater independence from water. B. Endothermy decreases the amount of time an animal spends hunting or foraging. C. Endothermy widened the range of habitats available and increased speciation. D. Endothermy allows more body resources to be used for growth and reproduction.arrow_forwardConsider an ectotherm and an endotherm of equal body mass. Which of the following would you expect to be true? -both animals require the same amount of energy per unit mass -the ectotherm requires more daily calories from food than the endotherm -the endotherm requires less energy per unit mass but more total energy than the ectotherm -the ectotherm requires less energy per unit mass but more total energy than the endotherm -the ectotherm could survive a longer period without food relative to the endothermarrow_forward
- How could the increasing global temperature associated with climate change impact ectotherms? a. Ectotherm diversity will decrease in cool regions. b. Ectotherms will be able to be active all day in the tropics. c. Ectotherms will have to expend more energy to cool their body temperatures. d. Ectotherms will be able to expand into new habitats.arrow_forwardwhich of the following statements are true about homeostasis? Select all that apply. a. The selective permeability of the cell membrane allows for thermoregulation. b. Homeostasis is an organism‘s way of maintaining constant and balanced internal processes. c. Ectotherms rely on environmental heat to maintain homeostasis. d. Homeostasis works by a system of positive feedback.arrow_forwardWhat is the trade-off of ectotherms with regard to maintaining an internal environment that doesn’t vary much? Ectotherms are larger than endotherms because they need to have a larger surface area to volume ratio in order to either increase or lower their temperature. Ectotherms usually have fur in order to conserve heat when they live in very cold environments. Ectotherms are smaller than endotherms because they need more surface area to dissipate heat relative to their insides. Ectotherms can survive in a wider variety of habitats because they are smaller and can behaviorally adapt to a wide variety of temperatures.arrow_forward
- Research the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation? Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions: ectotherm in cool conditions ectotherm in hot conditions Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.arrow_forwardEctotherms: They are otherwise called wanton creatures. Fishes, creatures of land and water, reptiles are ectotherms. Endotherms - they are otherwise called warm-blooded creatures. For example, birds and vertebrates are endotherms. Impact of temperature on endotherms - When the temperature is low, endotherms produce more hotness to keep the internal heat level steady. So endotherms are not influenced by the temperature of the climate. Impact of temperature on ectotherms - The temperature of the climate influences ectotherms. At the point when the temperature is high, ectotherms grow quicker. At the point when the temperature is low, they might foster injury. Provide biological reasoning for your claim about endotherms. Consider addressing the following: -Why do you see the data you see? -What is happening at the molecular level? -What are the benefits and disadvantages of being an endotherm. -How do endotherms maintain homeostasis?arrow_forwardEctotherms use more energy to maintain their body temperature than endotherms are better able to carry out intense, long-duration activity than endotherms have a more constant internal body temperature than endotherms gain most of their heat from external sources have a higher metabolic rate than similarly-sized endothermsarrow_forward

Describe trade-offs faced by endotherms vs ectotherms – focus on benefits and downsides for each. 2.) Discuss environmental pressures faced by organisms in a rocky intertidal zone. What adaptations do you expect to find in invertebrates living there? 3.) Discuss nutrient environments in freshwater habitats, and how they are related to the speed of water flow.arrow_forwardAmazingly, a water bear -microscopic invertebrates- can adjust its metabolism to zero and “hibernate” when the habitat dries.
