- When it comes to avoiding the worst impacts due to climate change, three things are sure: First, the need for (adaptation; mitigation; geoengineering; carbon capture and storage) will be inevitable. Second, (adaptation; mitigation; geoengineering; carbon capture and storage) should not be used as a primary solution. And third, (adaptation; mitigation; geoengineering; carbon capture and storage) should be the main component in climate policy.arrow_forward1) How could your eco-column be used to model the greenhouse effect? 2) Describe how your eco-column is used to model the nitrogen cycle. 3) Describe at least 3 transformations of nitrogen occuring in your eco-column and the organisms assisting in the transformation of nitrogen.arrow_forwardThe discipline that applies ecological principles to returningdegraded ecosystems to a more natural state is known as(A) restoration ecology.(B) thermodynamics.(C) eutrophication.(D) biogeochemistryarrow_forward
- Which of these hypotheses does not explain why increased CO2 levels in the atmosphere could cause a decrease in the productivity of some crops because of changes in climate? A) There could be increases in average winter temperatures that reduce the growth of crops. B) There could be decreases in precipitation in some regions that reduce growth in some crops. C) There could be shifts in the ranges of some important species in the community, such as pollinators, that cause reduction of growth in some crops.arrow_forwardDiscuss one critical factor that defines this differentiation between offshore and coastal primary productivity.arrow_forwardWhat does the term ’leakage’ mean in the context of regulating greenhouse gas emissions? and why is this important to consider?arrow_forward
- What are the similarities and differences of biogeochemical cycle and energy flow in the ecosystem?arrow_forwardDefine productivity as the word is used in ecology. What is a pri-mary producer? What is the distinction between gross productivity, net productivity, and respiration? How is net productivity related to biomass (or standing crop)?arrow_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_forward
