An organism is characterized by any individual entity, which shows the properties of life. Living organisms are categorized by taxonomy into particular groups like multicellular plants, animals, and

Answer to Problem 1TQ
All living organisms require energy in order to perform life processes. They are comprised of one or more cells, grow, respond to the surroundings, retain a stable internal environment, and reproduce.
Therefore, options (a), (c), and (e) are correct.
Explanation of Solution
Justify reasons for the correct statement:
A living organism must possess the following characteristics; requires energy to perform life processes, reproduce, comprised of one or more cells, maintain a stable internal surroundings, and evolve as groups. In the given options, oak tree, the fungus that causes white-nose syndrome in bats, and teacher exhibiting the characteristics of life. Therefore, they are considered as living organisms.
Option (a) is given as “an oak tree”.
Option (c) is given as “the fungus that causes white-nose syndrome in bats”.
Option (e) is given as “your teacher”.
Hence, options (a), (c), and (e) are correct.
Justify reasons for the incorrect statements:
Option (b) is given as “an influenza virus”.
An influenza virus meets only one criterion, which is evolving as groups. Other than this, it meets no criteria of life. Hence, it is a wrong answer.
Option (d) is given as “A diamond”.
A diamond encounters no criteria of life. Hence, it is a wrong answer.
Hence, options (b) and (d) are incorrect.
An oak tree, the fungus that causes white-nose syndrome in bats and a teacher are considered as living organisms, as they are exhibiting the characteristics of life.
