Grief is a normal and natural process that can involve a range of emotions such as sadness, anger, guilt, and despair.

There are several different types of symbiosis, including mutualism, commensalism, and parasitism. 1.1 Mutualism In mutualism, both organisms benefit from the relationship. An example of mutualism is the relationship between nitrogen-fixing bacteria and leguminous plants. The bacteria fix nitrogen gas from the air and convert it into a form that the plants can use as a nutrient, while the plants provide the bacteria with a place to live and grow.  Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an
