Question
Chapter 37, Problem 11TYK
Summary Introduction
To determine: The reason that the predatory animals such as sharks and tigers are relatively rare.
Introduction: Food chain is the transfer of energy from one trophic level to the other and the primary producers derive the most energy while the secondary or tertiary consumers derive the least. The energy transferred in each level is 10% of the previous level.

Animals are unable to make their own energy, yet you obtain energy when you eat animal food products. Explain how this illustrates the flow of energy through an ecosystem.
Gasping for Oxygen
Explain how each of the following contribute to dissolved oxygen decline in aquatic ecosystems:
Rising water temperatures
slowing streams
organic pollutants/eutrophication

Choose two answers that apply. A) eutrophication of the ocean leads to an increase in dissolved oxygen. B) photosynthesis by the phytoplankton increase the oxygen concentration of the ocean. C) decomposition of dead organic matter decreases the oxygen concentration in the ocean. D) cellular respiration by primary consumers increases the oxygen concentration in the ocean E) anaerobic respiration at the ocean floor decreases the carbon dioxide levels in the oceanarrow_forwardExplain why there are differences in the efficiency of energy transfer between trophic levels. Explain what happens to the energy which is not transferred to the next trophic level in a food chain when one organism feeds on another.arrow_forward
- A food chain would be a better resource than a food web to answer which question? a. How does energy move from an organism in one trophic level to an organism on the next trophic level? b. How does energy move within a trophic level? c. What preys on grasses? d. How is organic matter recycled in a forest?arrow_forwardWhich example below is a positive feedback relevant to Earth’s global energy balance? a. Increased temperature causes snow to melt. This exposes bare ground, which absorbs more solar radiation than snow, leading to further increases in temperature. b. Increased temperature causes snow to melt, which allows increased vegetation to remove CO2 from the atmosphere thereby reducing temperature. c. 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_forwardA desert ecosystem includes grasses, mice, snakes, and hawks.

A.Energy flow reaches an equilibrium within ecosystems such that every trophic level has the same amount of energy. B. Because forests have relatively few large trees which support numerous smaller organisms, they have less energy at the lowest trophic level than at higher trophic levels. C. Energy is recycled within ecosystems, moving from producers to consumers to decomposers and back to producers. D. Energy flows through ecosystems with some lost at every transition resulting in lower trophic levels always containing more energy than higher trophic levels. E. Aquatic ecosystems have more energy at higher trophic levels than at lower trophic levels, whereas terrestrial ecosystems have more energy at lower trophic levels.
