Name the bacteria found in the root nodules of leguminous plants and state the association of the bacteria with the leguminous plants

The name of the bacteria that could be seen in the root of leguminous plants is Rhizobium. And the association is symbiotic association

They are like nitrogen replenishers of the soil, A plot of land being cultivated for a time might lose its fertility, And as a part of it there could be a decrease of nitrogen content in the soil. And this could affect the crops grown in the field as nitrogen is needed for plant growth. Thus by planting leguminous plants in this field which we have taken as an example, will bring in the rhizobium bacteria which will be present in the root nodules and these bacteria via symbiotic relationship will fix atmospheric nitrogen into the soil which brings back the fertility of the land.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
