The law of thermodynamics denoted as d states that an energy can neither be created nor it can be destroyed.
00:18
It can only be transferred from one source to another source.
00:26
The same principle works in the tropical levels of the food chain.
00:35
That is, the energy that is obtained in the primary producers denoted as pp is from the sun.
00:45
It is not made in the primary producers.
00:48
The energy that is made in the primary producers denoted as e is transmitted through the other tropical levels of the food chain.

Usually, in the land ecosystem, the transfer of energy is less efficient when compared to the aquatic ecosystem.
01:20
That is, in the aquatic ecosystem, energy is transferred more efficiently.
01:27
This happens due to certain factors.
01:32
The first factor is, the primary producer...
