Explanation:
Maybe.. to provide nutrients of Soil and Water...
Bacteria may affect plants in a number of ways. Diseases have been mentioned, but most bacteria co-exist with plants quite easily. Several bacteria are involved with the transitions of nutrients and make nutrients such as nitrogen plant available (the plant is only able to absorb some nutrients in certain molecular forms). While other bacteria convert nutrients and toxins into forms unavailable to the plant.
Other bacteria make Some bacteria, Rhizobia in particular, develop symbiotic relationships with some plants. Rhizobia convert atmospheric nitrogen into ammonium which is plant available. In exchange, the plant provides Rhizobia with shelter (a root nodule) and food (photosynthates).
In the Tundra region, the diversity of the organisms present is high. Multiple different species of different organisms are present in these regions, which makes them a diverse area on the Earth. The mechanism responsible for these different populations is the species diversity.
It can be defined as the total number of species that are present in a given community.
