During the day, plants produce oxygen by splitting water molecules in the light-dependent reactions of photosynthesis.
Light-dependent reactions occur in thylakoid membranes of chloroplasts and begin with the absorption of light energy. This energy (together with water and photosystems) is used for the production of ATP and the reduced electron carrier NADPH which are necessary for the next stage of photosynthesis. Oxygen is released.
At the same time, plants use cellular respiration to produce some of the carbon dioxide needed by the light-independent reactions to make sugars.
Cellular respiration is a chemical reaction of plants where they use glucose and oxygen to produce carbon dioxide and water and release energy.
During the night, plants produce carbon dioxide, but not oxygen because only cellular respiration takes place.
There is no sunlight at night, so only the cellular respiration occurs.
Answer:
The answer is glucose
Explanation:
Glucose + Oxygen -> Carbon dioxide +Water + Energy
if you think about it it is just photosynthesis backwards
Answer:
Option (4)
Explanation:
Carbon forms the basin element for the existence of life. It is present in the atmosphere in the form of CO₂, which is one of the major green house gas. It plays an important role in the carbon cycle.
The increase in the concentration of carbon in the atmosphere can lead to the global rise in the temperature. It can lead to global warming. The amount of carbon in the atmosphere has been rising continuously, right after the industrial revolution.
The carbon is mainly emitted from the heavy industries and factories, vehicles, burning up of fossil fuels. It also increased due to the increasing absorption of solar radiation.
This emission of carbon if not controlled by the humans, then the concentration of carbon in the atmosphere will abruptly increase after some decades.
Thus, the correct answer is option (4).
The insects he sprayed will die therefore leaving the predators of the insects to decrease in population
