he equation below shows the process of photosynthesis.
Carbon dioxide + Water → Glucose + Oxygen
What forms of energy are entering and exiting this process?
a
Thermal energy is entering, and electrical energy is exiting.
b
Chemical energy is entering, and light energy is exiting.
c
Light energy is entering, and chemical energy is exiting.
d
Wind energy is entering, and light e
nergy is exiting.
nergy is exiting.
The correct answer is option c: Light energy is entering, and chemical energy is exiting in the process of photosynthesis.
The equation for photosynthesis shows that carbon dioxide and water are reactants (entering) and glucose and oxygen are products (exiting). In terms of energy, photosynthesis primarily involves the conversion of light energy into chemical energy.
So, the correct answer is c) Light energy is entering, and chemical energy is exiting.
To arrive at this answer, you can break down the equation and think about the types of energy involved at each step:
1. Carbon dioxide (CO2) enters the process from the environment.
2. Water (H2O) enters the process from the environment.
3. Sunlight (light energy) provides the energy to drive the process.
4. During photosynthesis, sunlight is captured by chlorophyll in the plant cells, and the energy is used to convert carbon dioxide and water into glucose and oxygen.
5. Glucose, a form of chemical energy, is produced and stored in the plant for later use.
6. Oxygen (O2) is released as a byproduct and exits into the environment.
So, light energy is entering the process as a form of energy, and chemical energy is exiting the process in the form of glucose.
