In Europe, the modern period had begun much arlier, that is, around 15th century. Their rapid growth in science and tecnnology, created the need for raw materials and other resources to feed their ndustries. This made them to explore other parts of the world for resources and establish trade relations. They used the resources of the other countries and strengthened their own economic and political base, eventually, leading on to govern that country. This came to be known as colonisation, and the countries used for trade became the colonies.This is how the British came to India, as traders and colonised the country. Indian historians also call the modern period in India as the colonial period.
Answer:
Nitrogen Fixation -Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrogen Assimilation -This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. FIXATION
Ammonification -Thisis part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back intoammonium so it can re- enter the nitrogen cycle. Nitrification- This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can thenabsorb. Denitrification -Extra nitrogen in the soil gets put back out into the air. There are special bacteria that perform this task as well.
