the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.

prejudice, stereotyping, and discrimination often go hand-in-hand, but it is also possible to have one without the others. when an ethnic group is stereotyped with a neutral or positive attribute such as "family-oriented," prejudice and discrimination may not be involved.

explanation:

while prejudice refers to biased thinking, discrimination consists of actions against a group of people. discrimination can be based on age, religion, health, and other indicators; race-based laws against discrimination strive to address this set of social problems.
