Considering the second law of

To examine: Whether the primary producers or the secondary producers would have greater or lesser biomass production in an ecosystem, considering the 2nd law of thermodynamics.
Introduction: The second law of thermodynamics states that “no energy transfer is 100% efficient; some energy is dispersed as heat”. In a living system such as in a cell, the second law of thermodynamics states that the capture and storage or use of energy is never 100% by the living cells. The energy is lost as disordered and metabolic heat energy.
Explanation of Solution
As per the 2nd law of thermodynamics, the useable energy decreases all the time. Only 10% of the original energy is useable for the successive trophic level, whereas 90% is lost in the form of heat. When the secondary producers or the primary consumers eat a primary producer (grass or plants), it is not all of the energy that is stored in the plant gets converted to useable energy. This is because during energy transfer, the energy is always lost due to entropy.
Therefore, it suggests that for maintaining its life functions, an organism must use much energy. The lost energy in the form of heat by an organism is no longer useable for them as well as for other organisms.
In the case of secondary producers, the biomass will always be less when compared to the primary producers because of 10% rule, and the successive energy transfer will always be less than that of the primary producers.
The typical biomass of the primary producers will always be greater than that of the secondary producers.

- Biology Questionarrow_forward✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.arrow_forwarddrawing chemical structure of ATP. please draw in and label whats asked.
