MAKE CONNECTIONS Review the discussion of feedback regulation in Concept 1.1. Could effects of globalwarming on peatlands alter CO2 concentrations in waysthat result in negative or positive feedback? Explain.
In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best supports the claim that this species is better adapted to environmental changes than other photosynthetic species are?
a) The additional pigments allow the species to outcompete other species for the wavelengths of light commonly used in photosynthesis.
b) The increased pigment concentration better facilitates energy production within the cells of the species.
c) The pigment combination allows the organism to absorb heat as well as light, making better use of available energy.
d) The additional pigments allow the species containing them to harvest energy from wavelengths of light that the other photosynthetic species cannot use.

- Which of the following approaches would be the most effective way to reduce greenhouse carbon dioxide? Increase waste deposition into the deep ocean Plant more environmentally-suitable plants Increase use of fuel sources that do not produce carbon dioxide as a by-product Decrease livestock agriculture.arrow_forwardplease draw! Create 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_forwarduestion 23 Which of the following statements most accurately describes the transport of zebra mus- sels to the Great Lakes due to anthropogenic activity? The zebra mussel was unintentionally transported to the Great Lakes on ships' hulls and in their ballast tanks. The zebra mussel was intentionally transported to the Great Lakes to improve the ecosystem. The zebra mussel was intentionally transported to the Great Lakes due to its visual appeal. The zebra mussel was unintentionally transported to the Great Lakes on the cargo crates of ships.arrow_forward
- Photosynthetic organisms are normally considered the most important primary producers; which organisms are primary producers in hydrothermal vent communities?arrow_forwardWhy would a C4 plant have a competitive advantage at high temperatures? a) There is more rubisco in all the cells of C4 plants. b) C4 plants use rubisco to fix carbon. c) C4 plants use PEP carboxylase to fix carbon. d) C4 plants have higher rates of photorespiration.arrow_forwardQ55: Mangrove trees and seagrasses along coastal areas near coral reefs are known to trap sediment (silt) before it makes its way to and clouds the water over reefs. Development of such coastal areas near coral reefs often results in the destruction of these plants. What is the likely consequence of this vegetation loss for the corals? Briefly explain.arrow_forward

Model/diagram the sources and sinks of carbon in the global ecosystem. You will need to create TWO models/diagrams of the sources and sinks of carbon. In the first model diagram the sources and sinks of carbon in a natural, pre-industrial landscape. In the second model, diagram the sources and sinks of carbon in a landscape altered by human activity and industry. Finally, write a few short sentences on what you would expect the atmospheric levels of CO2 to be in each model and why they would or would not be similar.arrow_forwardDescribe C4 plants: a.)What is the CO2 pathway? b.)How much carbon is lost via photorespiration? c.)What is an example species?arrow_forward
