Pam described two substances which participate in photosynthesis. substance a: combines with carbon dioxide to form sugar substance b: traps sunlight in green plants which statement is correct? substance a is water and substance b is oxygen. substance a is glucose and substance b is water. substance a is water and substance b is chlorophyll. substance a is chlorophyll and substance b is oxygen.

Substance A is water and Substance B is chlorophyll.

Explanation:

Photosynthesis is a process which occurs mainly in plants in which inorganic substances like carbon dioxide (CO2) and water (H2O) combine to form organic substance named as glucose (C6H12O6) which is a sugar. But in order for CO2 and H2O to react with each other energy is required. The source of this energy is sunlight which is captured by a pigment named as chlorophyll which is present in an organelle named as chloroplast of plant cell.

hello there the answer is d

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
