Question

Why do plants at the bottom of a pond grow better than the plants at the bottom of a lake

Answer 1

Because sunlight does not reach all the way to the bottom of the lake :)

Answer 2

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.
