Chapter 29, Problem 4RQ
Summary Introduction
To determine:
The first three trophic levels in an ecosystem.
Introduction:
Ecosystem is composed of all the biotic and abiotic components that exist together and interact with each other for their survival. An ecosystem consists of several trophic levels that mainly include the producers, consumers, detritivores, and decomposers. All the trophic levels in the ecosystem are interconnected with each other.

How would you describe the trophic levels in a typical ecosystem? Discuss the flow of energy through the ecosystem, the relationship between the different trophic levels, and the factors that limit the number of trophic levels.
When hunting disrupts the balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers.
Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following in completing the table below.

Hypothetical balanced food chain. Sun and Earth supply 6 units of energy to each plant. For higher tropic levels, individuals consume 2 units of energy each before passing the remainder to the next trophic level. The number of individuals in each trophic level is given below.

- Energy transferred from one trophic level to the next in an ecosystem is measured in calories, numbers, and in biomass. If a rangeland has a biomass of 100, 000g/m2 from the grass, how much biomass will be available in human beings who eat the cow that eat that grass?arrow_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_forwardHypothetical balanced food chain.

The number of individuals in each trophic level is given below. Complete the table below by computing for the number of energy units in each column. Answer the following questions: Discuss how the food chain works. Where does each trophic component or level get its energy (food) from? What is the ultimate source of energy for all components of the food chain? Which component got the highest amount of available energy/individual? Why do members of this component need the most energy?arrow_forward

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_forward
- Construct a biomass pyramid for the following hypothetical scenario. Be sure to include all four trophic levels in the pyramid, and provide the total biomass of living things found at each level. Be sure to include units, and label each trophic level. The shape of your pyramid should be based on the biomass of each trophic level. Levels with more biomass should be drawn wider, and levels with less biomass should be drawn thinner. Note that your biomass pyramid may or may not be a true pyramid. Scenario: Hickory Run Nature Reserve is a 150-acre conservation area filled with plants and animals native to the Mid-Atlantic region of the United States. A baseline study was done to determine the total biomass of producers and consumers living on the reserve. Baseline data will be compared to data collected in future years to determine trends in species accumulation or loss. This comparison is important because the region surrounding the reserve is experiencing a high rate of human development…arrow_forwardUsing the concepts of trophic levels and energy flow, explain why the ecological footprint of a vegetarian person is smaller than that of a meat-eaterarrow_forwardWhich of the following is true of trophic relationships in an ecosystem?
