Question

Fungi obtained energy______.
(a) directly from the Sun
(b) from inorganic material in the environment
(c) by absorbing organic molecules
(d) from nuclear fusion ​

Answer 1

Answer:

All fungi are heterotrophic, which means that they get the energy they need to live from other organisms. Like animals, fungi extract the energy stored in the bonds of organic compounds such as sugar and protein from living or dead organisms.

Answer 2

The answer is option c) by absorbing organic molecules

• As we know, fungi lack chlorophyll, therefore they cannot synthesise their own food.
• They depend on other species for their nutrition, hence they are called heterotrophs.
• They absorb the organic molecules of other species and with the help of their digestive enzymes, they can obtain their required energy.
• Fungi are classified as Saprophytes, Parasites and Symbiotes.
• In Saprophytic fungi, nutrition is derived from dead and decayed organisms.
• Parasitic fungi live on other organisms and also derive their nutrition from them.
• Symbiotic fungi grow on plant roots and obtain their nutrients from them. The plant also in turn gets its benefit from the fungi to absorb food and water. Hence they benefit from each other.
