Chang described two substances which participate in photosynthesis.

substance a: plants absorb sunlight.
substance b: gas formed with glucose.

which statement is correct?

- substance a is chlorophyll and substance b is oxygen.
- substance a is oxygen and substance b is carbon dioxide.
- substance a is glucose and substance b is carbon dioxide.
- substance a is carbon dioxide and substance b is oxygen.

- Substance A is chlorophyll and Substance B is oxygen.

Explanation:

Chlorophyll is the green coloring matter responsible for the green color of a leaf.

It helps in trapping sunlight for the purpose of photosynthesis.

In the event of photosynthesis, carbon dioxide is used, the gas produced is oxygen.

This makes the right choice be the first option.

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.
