  It is a description of all the biological, physical and chemical factors that a species needs to survive, stay healthy and reproduce.
  A niche is unique for a species, which means no two species have exact identical niches.

•Learning: The principles laid down therein are considered fundamental in the governance of the country, making it the duty of the State to apply these principles in making laws to establish a just society in the country. They were made non-justifiable keeping in view that the state may not have resources to implement them. DPSPS are not enforceable in a court of law.

Justification:
•Option (a): They do recognize. For example, certain laws that violate Article 14 of the Constitution can be declared legitimate if they fulfil DPSP under parts of Article 39.

• Statement 2: Rights such as equal pay for equal work, child nutrition, old age security are some of the rights that DPSP mandates the government to implement. So, 2 is correct.
•Statement 3: Statement 3 logically follows from Statements 1 and 2.
