Answer:
The correct answer is: A) the Calvin Cycle alone.
Explanation:
These reactions happen in cells capable of photosynthesis.
The only out of these reactions that require CO2 to take place is the Calvin Cycle. The Calvin Cycle is a series of biochemical processes that occur in the chloroplasts during photosynthesis. <u>The Calvin Cycle uses carbon dioxide (CO2) and water to produce glucose</u>, which will give energy to the cells.
The light reactions occur during photosynthesis in the presence of light and involving photophosphorylation. The light reaction does not make use of CO2, as it takes solar energy and converts it into NADPH and ATP.
The correct option is B.
In the ecosystem, energy flows from one trophic level to the other. The first trophic level is that of the producers which use the energy of the sun to produce their own food. Out of the energy obtained from the sun by the producers only about 3% of it is converted into food products. The second trophic level is made up of the herbivores and the omnivores which eat the plant. Only about 10% of the energy from the plant is transferred to the animals in the second trophic level. These second trophic level animals will also transfer about 10% of the energy they obtain to the animals in the third trophic level when they are eaten. Thus, it can be seen that the energy that is transferred in the ecosystem is gradually reducing from one trophic level to another.
Answer:
D
Explanation:
Not sure but the sentence is super understamdable
my guess is False i think that is the correct answer, because their are mammals that live in the tundra.
