Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
Answer:
The correct answer is "grass -> grasshopper -> raccoon -> wolf"
Explanation:
Food chains are diagrams that represent the order at which organisms feed from each other, starting from producers that are able to make their own food, until quaternary consumers that feed from predators. In this case, the sequence of grass -> grasshopper -> raccoon -> wolf can be found in the meadow. Grass is a plant that function as producer, which is consumed by grasshopper (primary consumer), which is consumed by raccoon (secondary consumer), which is consumed by wolf (tertiary consumers). I attached the missing information in a picture.
