snow_lady [41]

Answer:

Many species would eventually die off because they lack a food source.

Explanation:

<u>Photosynthesis can be defined simply as the biological process of using light to synthesize food (in the form of glucose). It is a process that takes place in plants and involves the synthesis of sugar using inorganic products such as water and carbon dioxide.</u>

6CO_2 + 6H_20 + (energy) → C_6H_1_2O_6 + 6O_2

The process consists of two stages namely;

  • Light reaction
  • Light independent reaction.

The products from the light reaction are utilized in the light-independent reaction.

<em>Hence, without light energy, the process of photosynthesis cannot proceed and plants will not be able to manufacture foods. Without foods, many plant species would die off. </em>
