Concept explainers
About 10 million species functions in the transfer of energy and cycling of carbon, nitrogen, phosphorous, nitrogen molecules through the food web. They are algae, plants, as well as bacteria. These organisms are able to conduct respiration as well as photosynthesis.
Explanation of Solution
Animals, plants as well as microbes obtain necessary compounds like carbon, energy, and organic compounds from the photosynthetic organisms. Microbes, amoebas, and humans might use the same biochemical pathway for respiration but differ in the kind of food which they eat.
Photosynthetic bacteria and green plants are some of the photoautotrophs. Photosynthetic organisms possess structural as well as physiological adaptations to survive in their environments across the globe or diversified environment. Consumers survive through specialized adaptations such as perception, behavior and limb specialization to obtain their food.

- Why do we need green plants and other living things that carry out photosynthesis?arrow_forwardDescribe the path of a carbon atom through the carbon cycle. Be sure to include the roles of photosynthesis and respiration in each explanation a) Describe your journey starting as a CO2 molecule in the bottom layer dissolved in the water. Describe at least 3 transformations and the organisms involved. b) Describe the journey starting as a molecule of CO2 in the "atmosphere" of the top layer of the bottle. Describe at least three transformations and the organisms involved. c) How could your eco-columnbe used to model the greenhouse effect?arrow_forwardHow does the availability of CO2 in water limit the photosynthetic rate in aquatic autotrophs?arrow_forward
- Discuss: 1) the mechanisms that transport photosynthate from sources to sinks. Why is this important on a physiological level and a societal level?arrow_forwardOxygenic photosynthesis, in cyanobacteria, green algae, and green plants, consumes which of the following substrate molecules? H2O, CO2, and C6H12O6 C6H12O6 and O2 only CO2 and C6H12O6 only CO2 and H2O only C6H12O6, H2O, and O2arrow_forwardFrom a plant's perspective, the main purpose of photosynthesis is to Group of answer choices a)to produce sugars and oxygen for heterotrophs. b)plants are not cognitive organisms and therefore we have no idea what the "purpose" of photosynthesis is for the plant. c)to produce enough O2 gas for the plant to survive through the night. d)make sugars, such as glucose, to use for building cell walls and for energy needed by the plant.arrow_forward
- Why might chemosynthetic communities exist only in places like the deep-ocean floor rather than across a wide range of land and sea habitats, the way photosynthesis-based communities are?arrow_forwardPhotosystem II uses sunlight to strip electrons (and protons) away from which of the following substrate molecules (in the chloroplasts of green plants and green algae)? C6H12O6 only C6H12O6, H2O, and CO2 only CO2 only H2O and C6H12O6 only H2O onlyarrow_forwardWhy don’t just a few species dominate the world’s photosynthesis?arrow_forward
- If ribulose bisphosphate were removed from a chloroplast, which of the following statements would BEST describe the immediate result? b)ATP could not be produced in the thylakoid a) CO2 could not enter the Calvin cycle d) Light energy could not be trapped in the grana c) 02 could not enter the Calvin Cyclearrow_forwardMatter is constantly cycled between living and non living parts of the environment. Processes like photosynthesis and respiration allow the carbon cycle to regenerate needed substances by recycling earth’s atoms. A diagram of the carbon cycle is shown. Each arrow represents a process in the cycle. Which explanation best describes the process in the cycle. Which explanation best describes the process that occurs at the arrow marked B? A) plants use carbon dioxide from the atmosphere in the process of photosynthesis to produce glucose B) plants release carbon dioxide into the atmosphere in the process of photosynthesis to produce glucose C) plants use carbon dioxide from the atmosphere in the process of cellular respiration to convert glucose to atp energy D) plants release carbon dioxide into the atmosphere in the process of cellular respiration to convert glucose to atp energyarrow_forwardImagine you are a botanist and you recently discovered a new species of plant in the unexplored regions of the Amazon Rainforest. This plant thrives in the diverse ecosystem of the Amazon and, surprisingly, can survive with limited sunlight. This unique attribute of the plant could have potential impacts on both the field of ecology and various industries. Your primary research focus is now to investigate the efficiency of photosynthesis in this plant, specifically analyzing the structure of the chloroplasts and the distribution of pigments (chlorophyll and carotenoids) utilizing microscopy techniques. Both traditional fluorescence microscopy (FM) and CSM are capable of identifying the distribution of pigments (chlorophyll and carotenoids). How does the process of stimulating fluorescence and detection vary between these two microscopy techniques? Given these differences, which method would be more likely to yield superior results for your research? Please provide your reasons, taking…arrow_forward
