Ponds are generally much smaller in size, and have shorter depth, in comparison to the lakes. These ponds have a depth of about 5 to 6 feet. So, the sunlight easily penetrates the bottom of the pond, which is very essential for plants to carry out the process of photosynthesis. These aquatic plants obtain the necessary nutrients along with the sunlight, as a result of which they can flourish and grow more conveniently compared to the lakes.
Thus, the plants (aquatic plants) that grow at the bottom of the pond grows better than the plant that are present at the bottom of the lake.
If it follows the same pattern shown on the data table then the aproximate distance for a galaxy that has a velocity of 30000 km/s would be 1960 million light years and would be between the galaxy C and galaxy D.
