- There is a symbiotic relationship between algae and fungus. For example, in organisms called lichens, a chlorophyll-containing partner, which is an alga, and a fungus live together.
- The fungus provides shelter, water and minerals to the alga and, in return, the alga prepares and provides food to the fungus. The bacterium called Rhizobium can take atmospheric nitrogen and convert it into a usable form.
- But Rhizobium cannot make its own food. So, it often lives in the roots of gram, peas, moong, beans and other legumes and provides them with nitrogen. In return, the plants provide food and shelter to the bacteria. They, thus, have a symbiotic relationship. (i.e., between plants and bacteria).

Symbiotic Relationships in Biology
Symbiotic relationships occur when two different species interact with each other in a way that is mutually beneficial to both. There are three main types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism is the type of symbiosis where both species benefit from the interaction, commensalism is where one species benefits while the other is unaffected, and parasitism is where one species benefits at the expense of the other.
Examples of Symbiotic Relationships
1. Algae and Fungus: Lichens are a classic example of mutualism, where algae and fungus form a symbiotic relationship. The algae provide the fungus with food through photosynthesis, while the fungus provides a protective environment for the algae to grow.
2. Algae and Bacteria: Another example of mutualism is the relationship between algae and bacteria. The bacteria provide the algae with nitrogen and other nutrients, while the algae provide the bacteria with food and oxygen.
3. Fungus and Bacteria: Some species of fungus form a symbiotic relationship with bacteria, where the bacteria help break down organic matter, making it easier for the fungus to absorb nutrients.
4. Plants and Bacteria: Many plants form a symbiotic relationship with bacteria in their roots, where the bacteria help fix nitrogen from the air into a form that the plant can use for growth.
Answer Explanation
Out of the options given, only examples 1 and 4 involve a fungus, and only example 1 involves algae. Therefore, option C, "1 and 4 Only," is the correct answer.
