To summarize: How O2 (oxygen) and CO2 (carbon dioxide) are used and produced by the aerobic algae and by the chlorarachniophytes with the help of the figures, Refer Fig.9.2 "Energy flow and chemical recycling in ecosystems", and Fig.10.6 "An overview of photosynthesis: Cooperation of the light reactions and the Calvin cycle” in the textbook.
Concept introduction: Chlorarachniophytes comprises of a small group of the cercozoans. These possess secondary endosymbiosis and are mixotrophic. These organisms ingest small protists and also perform photosynthesis. Aerobic algae also perform the process of photosynthesis and

- Name the green algal group from which plants are hypothesized to have descended and describe supporting evidence.arrow_forwardMAKE CONNECTIONS What is a general term that isused to describe the strategy of using photosynthesis andheterotrophy for nutrition (see Concept 28.1)? What is awell-known class of protists that uses this strategy?arrow_forwardWRITE ABOUT A THEME: INTERACTIONS Organisms interactwith each other and the physical environment. In a shortessay (100–150 words), explain how the response of diatompopulations to a drop in nutrient availability can affect bothother organisms and aspects of the physical environment(such as carbon dioxide concentrations).arrow_forward
- Cite 3 scientists who made great contributions in the discovery/study of photosynthesis. Explain their discoveries in relation to photosynthesis.arrow_forwardMAKE CONNECTIONS Based on Figure 9.17, explainwhy hydroponically grown plants would grow muchmore slowly if they were not sufficiently aerated.arrow_forwardMAKE CONNECTIONS How might the enzymes of thermophilesdiffer from those of other organisms? (Review enzymes in Concept 8.4.)arrow_forward
- QNo3: How plants fix atmospheric nitrogen? Explain the role of microbes in plant growth?arrow_forwardRespond to the following questions. Why might it seem surprising that green light can drive any photosynthesis, given that chlorophyll, the major photosynthetic pigment, is green? How can it do this? Suppose that CO2 levels were to rise to 600 ppm, which in fact probably was their level about 300 million years ago. What effect would you suppose that might have regarding competition between C3 and C4 plants? In other words, which of the two kinds of plants would the change favour and why?arrow_forwardWhat are the roles of the following processes in the carbon cycle: photosynthesis, cellular respiration, combustion, and erosion?arrow_forward
- Q. find another carbon cycle diagram and compare it with the diagrams attached. include detailed analysis of the two diagrams attached. include an image of the new image of carbon cyclearrow_forwardMAKE CONNECTIONS As noted in Figure 52.15, theaddition of nutrients to a lake can cause an algal bloom.When these algae die, complex molecules in their bodiesare broken down by decomposers using aerobic respiration. Explain why this would reduce the lake’s oxygenlevels (see Concept 9.1)arrow_forwardDiscuss: 1) the mechanisms that transport photosynthate from sources to sinks. Why is this important on a physiological level and a societal level?arrow_forward
