Answer Details
The relationship between microorganisms and plants in the nitrogen cycle is best described as symbiosis.
Nitrogen is an essential nutrient for plant growth and is often limited in soil. Nitrogen gas makes up about 78% of the Earth's atmosphere, but it is not in a form that plants can use. The nitrogen cycle is a process by which nitrogen is converted into a usable form for plants, and microorganisms play a vital role in this process.
Some microorganisms, such as nitrogen-fixing bacteria, form a symbiotic relationship with plants. These bacteria live in the roots of plants and convert nitrogen gas from the atmosphere into a form that plants can use, such as ammonia or nitrate. In return, the plant provides the bacteria with carbohydrates and other nutrients.
Other microorganisms, such as nitrifying bacteria, convert ammonia into nitrate, which is also used by plants. Still, others, such as denitrifying bacteria, convert nitrate back into nitrogen gas, completing the nitrogen cycle.
Overall, the relationship between microorganisms and plants in the nitrogen cycle is best described as symbiosis, as they rely on each other for survival and growth. Without microorganisms, plants would not have access to the nitrogen they need to grow, and without plants, microorganisms would not have a source of energy and nutrients.
