Vegetative Propagation is defined as a form of asexual reproduction of a plant. It occurs when only one "parent plant" is involved in producing an offspring that will be genetically identical to the parent.
Nitrogen-fixing bacteria change nitrogen into a form of soluble nitrates that plants can use ...the air is 80% nitrogen but it is in N2 form which plants cannot use
2. High birth rate, zero death rate, high immigration, zero emigration
This is because birth rate and immigration increase population size, and death rate and emigration decrease population size, so maximizing the former and minimizing the latter are ideal
