Which of the following statements is a correct distinction between autotrophs and heterotrophs?

a. Only heterotrophs require chemical compounds from the environment.
b. Cellular respiration is unique to heterotrophs.
c. Only heterotrophs have mitochondria.
d. Only autotrophs can live or nutrients that are entirely inorganic.

Expert Solution & Answer

Summary Introduction

Introduction:

Photosynthesis is the process of conversion of light energy into chemical energy and organic molecules. This process is performed in chloroplasts of algae and plants. All animals for food depend on this conversion.

Answer to Problem 1SQ

Correct answer:

The distinction between autotrophs and heterotrophs is that only autotrophs can live on nutrients that are entirely inorganic. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

Autotrophs are the organisms that synthesis their own food such as lipids, nucleic acids, proteins and carbohydrates from inorganic matter like carbon dioxide, water and minerals.

Option d. is given as “only autotrophs can live on nutrients that are entirely inorganic”.

As, “the distinction between autotrophs and heterotrophs is that only autotrophs can live on nutrients that are entirely inorganic” it is the right answer.

Hence, option d. is the correct answer.

Reasons for the incorrect statements:

Option a. is given as “Only heterotrophs require chemical compounds from the environment”.

Heterotrophs are also known as consumers that depend on the organic matter produced by the autotrophs because they cannot utilize the inorganic material present in the surroundings. So, it is the wrong answer.

Option b. is given as “Cellular respiration is unique to heterotrophs”.

Cellular respiration is the chemical process in which the stored energy in the chemical bonds is converted into ATP by action of O₂. This process occurs in the cells of heterotrophs as well as autotrophs. So, it is the wrong answer.

Option c. is given as “Only heterotrophs have mitochondria”.

Mitochondria are known as “power house of the cell” and it is present in autotrophs and heterotrophs which help in production of ATP through respiration. So, it is the wrong answer.

Hence, options a., b. and c. are incorrect.

Conclusion

The autotrophs are known as producers because they can synthesis their own food by converting inorganic matter like carbon dioxide, water and minerals into chemical energy in the form of sugar organic compound).
