Question

symbiotic nitrogen fixation simply means

Answer 1

Symbiotic nitrogen fixation refers to the process by which certain plants, typically legumes, form a mutualistic relationship with specific bacteria known as rhizobia. In this symbiosis, the bacteria reside in the root nodules of the plants and convert atmospheric nitrogen (N₂) into a form of nitrogen (ammonia) that the plants can use for growth. In return, the plants provide the bacteria with carbohydrates and other organic compounds produced through photosynthesis. This relationship enhances soil fertility and provides essential nutrients to the plants.
