- Availability of energy is less for entities at higher trophic levels.Why?arrow_forwardDesign a logical food-web model of the living things in a typical deciduous forest. Producers should form the bottom of the web, with primary consumers and secondary consumers in the middle of the web, and tertiary consumers at the top of the web. Detritivores can be found throughout the web. Draw lines between the organisms that directly interact with each other. Organisms may have more than one line drawn from them or to them. In your model, include the sun, and illustrate how heat is lost as energy transfers from one trophic level to the next. Producers: maple tree dogwood tree spicebush (flowering shrub) Jack-in-the-pulpit (flower) Primary Consumers: spicebush swallowtail butterfly honeybee carpenter ant Secondary Consumers: woodpecker garter snake flycatcher (inset-eating bird) Tertiary Consumers: falcon screech owl bobcat Detritivores: bacteria earthworms flies fungiarrow_forwardThe average efficiency of energy transfer between trophic levels is 10%. Use this efficiency to determine how much phytoplankton mass is required to add just 1 gram (0.04 ounce) of new mass to a killer whale, which is a third-level or top carnivore. Create a diagram that summarizes the different trophic levels and the relative size and abundance of organisms at each level. How would your answer change if the efficiency were half the average rate? Twice the average rate?arrow_forward
