Question
Chapter 38, Problem 4WIO
Summary Introduction
To determine:
The total amount of organic material, available energy and nutrients in the ecosystem change over time. When a small ecosystem is build in which light and gas exchange was blocked with the environment.
Concept introduction:
A small ecosystem was built by a person. In which, he had blocked the light and gas exchange from the environment. Ecosystem is a biological community made up of living and non living components such as plants, animal, air and water. Biotic and abiotic components are linked together by different cycles.

Can you consider a living thing that does not seem to interact with other living things as a component of an ecosystem? Why or why not? Give a specific example to illustrate.
A scientist built a model ecosystem that contains air, plants, and animals that eat those plants. The model ecosystem is sealed so no material can get in or out, but the glass sides allow light in when the scientist switches the light on. When the scientist switches the light off, the model ecosystem is in the dark. The number of energy storage molecules in the plants and animals inside the model ecosystem started out high. Then the number of energy storage molecules began to decrease. Was the decrease because the light was switched on or because it was switched off? What happened to the amount of carbon dioxide in the air? *

- Which of the following is/are generally true of ecosystems? More than one option may be correct. Select ALL that are true. > Ecosystems consist of the community together with the abiotic environment of an area. Decomposers return nutrients such as phosphorous from dead animals back to autotrophs. Energy and nutrients are continuously recycled in ecosystems. Only 90% of energy is transferred between trophic levels. Energy and nutrients can pass from carnivores to herbivores to autotrophs.arrow_forwardEcosystem is an independently functioning unit with the most important processes being energy flow and nutrient cycling. Using food chain and biogeochemical cycles as examples, explain both the processes and its importance in functioning of Ecosystem.arrow_forwardCompare and contrast the roles of producers, consumers, and decomposers in the ecosystem. How does this relate to the hierarchical level of organization we see in biology?arrow_forward
- Also from the biological standpoint, several types of ECOSYSTEM and their corresponding components are distinguished. Select one type of these ecosystems that you can find near your place of residence. Identify that specific type of ecosystem. Categorize the component organisms present ONLY in that particular ecosystem. Using these representative organisms (those given in 2b above), make a diagram to clearly illustrate a food web to show the flow of energy in that ecosystem.arrow_forwardDescribe how energy flows through a hypothetical food chain from the bottom to the top. What happens to the numbers of individuals in each level as you move up the chain? In order to turn your food chain into a food web, what might you change about the trophic habits of its members?arrow_forwardYou now know what an ecosystem is—and how varied ecosystems can be. Pick an ecosystem near you—find one that it as large or small as you wish. All areas—urban, suburban, and rural—have many ecosystems to choose from. Write a description of the ecosystem, including biotic and abiotic factors, in NO MORE THAN FOUR SENTENCES.arrow_forward
- What would happen in an ecosystem if suddenly there were no decomposers?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_forwardName two examples of man-made ecosystem.arrow_forward
- Consider the meaning of the term "ecology." Select an area you would like to focus on (California). How do the basic chemicals (water, carbon, nitrogen) cycle through the ecosystem? You will want to include the main plants, animals, and the biome.arrow_forwardWhat is one example of an ecosystem service? How would life be different without that service?arrow_forwardIf you had to monitor an ecosystem for evidence of pollution, what are one or two indicator species you would want to pay particularly close attention to? You may discuss specific species of organisms, or can discuss organisms that occupy a specific trophic level in an ecosystem’s food web. Explain why you would select these species or this trophic level.arrow_forward
