Answer:

Although all of the options are important but the best reason is

a) Nitrogen is an essential part of biological molecules such as proteins and nucleic acids (DNA).

  • Nitrogen is an essential component of building blocks of life that are DNA, RNA and Protein. It is also needed for the production of chlorophyll. We can say there would be no life without nitrogen.
  • Air we breathe is 78% nitrogen but that is in inert form (N2) and we can't use it.
  • Nitrogen cycle is the process by which nitrogen circulates into various forms of nature and it make the nitrogen useful to carryout life.

Photosynthesis consists of which two primary steps
GarryVolchara [31]

Answer:

Light reactions and Calvin Cycle

Explanation:

The products of the light reaction become the products of the Calvin cycle (which is the dark stage) of photosynthesis. The light reaction is called so because it harnesses the energy of the sunlight photons to split water molecules into H+ and O- . The CO2 is then reduced to glucose using the H+ in the Calvin cycle without the need for sunlight - hence referred to as the dark reaction. The light reaction occurs in the grana while the dark reaction occurs in the stroma.
