option d

Symbiosis is a process in which two organisms lives in a close relationship and are benefitted from each other. In this no organisms will be harmed. Lichen (symbiosis of algae and fungi) and Rhizobium and a legume are the examples of symbiotic organisms which shows the process of symbiosis. In symbiotic relationship of algae and fungi, algae (photosynthetic) provide the energy for the fungus while the fungus breaks down the substrate and provide the nutrients for the algae.

Answer 2

(d) Both (a)-Lichens and (b)​- Rhizobium and a legume are a pair of symbiotic organisms.

Explanation:

• A mutually beneficial association between two distinct creatures is known as a symbiotic relationship.
• Lichen (algae-fungi symbiosis) and Rhizobium and a legume are two examples of symbiotic organisms that demonstrate the symbiotic process. Algae (photosynthetic) provide energy to the fungus, while the fungus breaks down the substrate and provides nutrients to the algae in a symbiotic interaction.
• The mutually beneficial symbiotic interaction of green algae and/or blue-green algae (cyanobacteria) dwelling among filaments of a fungus, generating lichen, is known as lichen symbiosis.
• The Rhizobium-legume symbiosis is unique in that it provides significant agricultural benefits as well as aids in preserving the balance between living species.
