The relationship between bacteria and legumes that results in nitrogen is best described as
a. parasitic
b. mutualistic
c. commensalistic
d. none of the above

The correct answer would be b. mutualistic.

Mutualism is a type of biological interaction between two species in which both the organisms get benefited from each other.

Bacteria present in the root nodules of leguminous plants help the plant in absorbing nitrogen from the soil by fixing atmospheric nitrogen into nitrogenous absorbable compounds such as ammonia.

In return, bacteria get shelter and food in the form of carbohydrates from the plant.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

answer: grassland biomes are closer to the equator and receive more rain.
