Question

From which type of compounds do organisms obtain E (energy)?

a) Organic compounds
b) Inorganic compounds
c) Mineral compounds
d) Synthetic compounds

Answer 1

Organisms obtain energy from organic compounds which contain carbon as their principal element.

Step-by-step explanation:

Organisms primarily obtain energy (energy) from organic compounds. These compounds contain carbon as the principal element, bonded to hydrogen and possibly other elements. Organic compounds, crucial for life, include carbohydrates, proteins, fats, and nucleic acids, which are essential for the structure and functioning of all living cells. Autotrophs, like plants, synthesize organic compounds through photosynthesis, while heterotrophs, such as animals and fungi, obtain them by consuming other organisms. Some prokaryotes, known as chemotrophs, can also utilize organic (chemoorganotrophs) or inorganic compounds to gain energy. Hence, the answer to the student's question on which type of compounds organisms obtain energy from would be (a) organic compounds.
