B Correct answer
Explanation

The amount of energy and biomass in the producers of the food chain is 100%. At each successive level, the energy and biomass are lost. The organisms at each level use energy for respiration. This is called respiration loss. When producers are eaten by the herbivores, there is 20% respiratory loss as producers use about 20% of energy in the form of respiration. Similarly, when herbivores are eaten by carnivores, there is 30% respiratory loss as 30% of energy is used by herbivores. Also, about 60% of the energy is used by carnivores during respiration. Hence, respiratory loss from carnivores to decomposer is 60%. 

Thus, the correct answer is '20%, 30%, 60%'.

A Correct answer
Explanation

The phlogiston theory is a scientific theory which states that the fire-like element is referred to phlogiston which is released during the process of combustion and explains the process of combustion and rusting which is together called as oxidation.

Antoine Lavoisier opposed this theory of phlogiston, he is called as father of modern chemistry. He discovered oxygen and told about its properties and chemical reactions. He has given a theory of combustion in which he has mentioned the rate of respiration and the relation between combustion and respiration, where oxygen is used in both the process.
So , correct option is ' Antoine Lavoisier ' .

C Correct answer
Explanation
Cellular respiration is a process takes place in the cells of the organism to convert biochemical energy from nutrients into ATP. It include breaking down of sugar in the presence of oxygen. This process was discovered by Thomas Adams.
So, the correct answer is 'Thomas Adams'.
