Answer:
Yes, it is a reasonable conclusion.
Explanation:
The long lasting gas that kept sunlight from penetrating the atmosphere was the key factor that promote a disturbance on the chain food. Without sunlight, plants could not produce their own energy, therefore they could not resist to this environment condition and die. That way, the herbivores could not feed and die as well. Also the carnivore could not survive because their supply of food of herbivores are not alive anymore. This scenario would promote a mass extinction of every dinosaur.
The Permian period ended in the greatest extinction of the Phanerozoic Eon
Answer:
The correct answer will be-establish the relationship between the amount of the carbon dioxide and the rate of photosynthesis
Explanation:
Theodor W. Engelmann performed the experiment on algae to study the action spectrum of photosynthesis for which he used a prism which scattered the white light into seven colors (VIBGYOR).
He grew the filamentous algae called Spirogyra which could perform photosynthesis and aerobic bacteria which could use oxygen produced as a result of photosynthesis utilizing Carbon dioxide.
The bacterial colonies grew in regions of test tube which received red and blue light showing that photosynthesis is active in this area.
The experiment also helps establish the relationship between the amount of carbon dioxide and the rate of photosynthesis observed by the production of oxygen in that area and the congregation of bacteria in that area.
