Answer:
In an aquatic ecosystem, the plants are present both on the subsurface and bottom bed rock of the aquatic body. These are the producers of the ecosystem because they provide food to the living organism in the lake. In day plants growing on the surface of the water takes up carbon dioxide from the atmosphere which is being absorbed in the water, to conduct the process of photosynthesis. These plants release oxygen, which supports the life of aquatic animals. In this way plants limit the abundance of carbon dioxide in water. But in night plants undergo a process of respiration, which releases carbon dioxide. The abundance of carbon dioxide increases in night along with the carbon dioxide being absorbed from the atmosphere. Therefore, concentration of carbon dioxide increases considerably in night as compared to day.

B. 25% of the area is vegetation and 75% is roofed or paved
C. 50% of the area is vegetation and 50% is roofed or paved
D. All of the above will have the same runoff
Answer: The correct option is B. 25% of the area is vegetation and 75% is roofed or paved.
Vegetation can cause precipitation and reduce runoff. Leaves and stems are used in capturing rain and prevents the rainwater to reach the ground. Dense vegetation with higher surface area under vegetation absorbs water and prevents runoff. Pavements or roofs cause the runoff water by filling the waterways as there is no vegetation for water absorption which leads to overfilled waterways and in turn cause flooding.
