Describe nitrogen cycle in nature with help of diagram,
Answers
Explanation:
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmospheric nitrogen,[16] making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

Answer:
Rhizobium is a bacteria that establishes itself on the roots of leguminous plants to form specialised structures called nodules. In these structures the bacteria are able to convert atmospheric nitrogen into ammonia, a process called nitrogen fixation. The ammonia is used by the plants as a nitrogen.
