Chapter 58, Problem 2S
Summary Introduction
To discuss:
The problem of ecosystem conversion is unique the way humans understand or not and examples for guidance to make the decisions.
Introduction:
The ecosystem can be defined as the community in which the living components of the community interact with the nonliving components. The ecosystems provide various valuable things. However, sometimes converting the ecosystem becomes more important than maintaining it.

- (A) The above figure indicates how much biologically productive land is needed to support different activities (e.g. 'carbon' is land needed to offset carbon emissions from energy production; 'cropland' is land needed to grow crops for food). What Goes it say about the sustainability of our lifestyle? Explain. (B) The world's ecosystems provide many valuable services, that we all benefit from. Yet, these services are often undervalued and taken for granted. Why? For full credit, provide an example with at least one specific ecosystem service. (C) Humans are impacting ecosystems (and their services) in many ways, often negatively. Throughout this course we've discussed some simple actions that can be taken by individuals to help mitigate our impact on the environment. List one action and specify how it can help.arrow_forwardExamples of ecological restoration include all of the following EXCEPT: - building levees to minimize the water that enters a floodplain. - eliminating invasive species. - replanting a forest. - removing a dam. - using periodic, controlled burns to promote native prairie plants in an abandoned farm field.arrow_forwardCER SCENARIO #1 This ecosystem is being affected by the development of a neighborhood. Acres are being cleared for building homes and roads. The people who have already moved in are complaining about the foxes that have been going through their yards and have even tried to catch small cats and dogs as prey. It was decided that the foxes would be trapped and relocated far away from the new neighborhood. PROMPT: WRITE A CLAIM STATEMENT ABOUT WHAT COULD HAPPEN TO THIS ECOSYSTEM WITH THE REMOVAL OF THE FOXES. CLAIM: EVIDENCE: REASONING:arrow_forward
- According to the resource-ratio hypothesis (a.k.a. R-star), what factor(s) will determine the maximum number of competing species that could possibly coexist in a community? (Note: either one or more-than-one answer could be correct) .what does the number of limiting resources in a community tell us? The number of limiting resources in the community The net primary productivity of the community (NPP). The number of trophic levels that are present in the community. | The intrinsic rate of increase (r) of each species in the community. The colonization rate of each species that can access the habitat.arrow_forwardOrganisms that damage crop plants are the most costly of introduced species. Weeds, pathogenic microbes, and arthropods that attack crops together account for half of the costs documented by Pimentel and his colleagues. What steps can we—farmers, governments, and all of us as a society—take to minimize the impacts of invasive species on crops?arrow_forwardIn the recent years there had been so many efforts to save mother earth from global warming, these includes earth hour, tree planting, no single-use plastic policy, takbo para sa kalikasan, etc. If you were given a chance to plan for a project to protect the earth, what would it be?

- What makes an ecosystem resilient? Use this sentence starter: ecosystems are resilient because... Use THE TEXT GIVEN ONLYarrow_forwardCreate a model which accurately, in detail, depicts the potential pathways of carbon (biomass) and energy in an ecosystem with at least five trophic levels (don’t forget your decomposers, they can count as one trophic level). Make sure to incorporate the multiple pathways that biomass and energy could take at each trophic level. Lastly, clearly illustrate how carbon and energy flow in this ecosystem. Be sure to include adequate levels of detail for all pathways and differentiate the flow of carbon and energy in your model.arrow_forwardA conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Why does the organism’s interaction appear in an oscillating pattern? What does it suggest?arrow_forward
