- Write testable hypothesis regarding how the quality of light (varying in wavelengths) and may affect the rate of photosynthesis. We’ll utilize a model organisms Chlorella (an algae) and detect a pH change in response to rate of photosynthesis. H0: HA:Which molecule absorbs the energy of a photon in photosynthesis? a. ATP b. glucose c. chlorophyll d. waterCompare how autotrophs and heterotrophs acquire energy.
- Phytoplankton is an aquatic autotroph. Describe its role in the food web. refer to pictureDraw a concept map of energy transfer using the following images. Note which uses photosynthesis, respiration, and fermentation.Which type of organism does NOT photosynthesize? a. Heterotrophs b. Producers c. Cyanobacteria d. Algae e. Autotrophs
- Differentiate the two types photosynthesis.Describe 3 factors that could inhibit primary production. Use examples to explain how autotrophs can adapt to these factors.Give typing answer with explanation and conclusion A biologist is measuring photosynthesis and respiration in a lake. She places a pair of bottles in the lake and measures the initial oxygen concentration to be 9.56 mg O2/L. Twenty-four hours later, she measured the oxygen concentrations in the light and dark bottles: 8.23 mg O2/L in the dark bottle and 10.11 mg O2/L in the light bottle. Calculate the hourly rates of NPP and respiration for this ecosystem. Be sure the units are correct. A) NPP=0.0229 mg O2/L/h, R=0.0554 mgO2/L/h B) NPP=.55 mgO2/L/h, R=1.33 mgO2/L/h C) NPP=-0.0554 mgO2/L/h, R= -0.0229 mgO2/L/h D) NPP=0.0229 mg O2/L, R=0.0554 mgO2/L
