Question

A large asteroid impact occurs, kicking up dust that blocks the Sun and prevents plants from photosynthesizing. What would most likely happen as a result of the asteroid impact? More earthquakes would occur across the planet. Some plants would evolve to use dust as a source of food. Many plants would perform photosynthesis without sunlight. Many species would eventually die off because they lack a food source.

Answer 1

Answer:

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

Explanation:

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.

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

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.

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.
