Answer:
(i) Available in the plant:
Chlorophyll
(ii) Available in the soil:
Water
(iii) Available in the air:
Carbon dioxide
(iv) Available during day:
Light / Light energy
Explanation:
For photosynthesis, your raw materials are chlorophyll (to absorb light energy from the sun), light, carbon dioxide, and water. The products are glucose and oxygen.
Chlorophyll can be found in the leaves of a plant.
Light is from the sun.
Carbon dioxide is taken in from surrounding air.
Water is taken in by the roots, along with mineral salts, before being distributed to other parts of the plant.
During the night, respiration takes place. You can think of it as opposite of photosynthesis. Materials are glucose and oxygen, and products are carbon dioxide and water.
