Assertion and ReasonAssertion (A): Energy flow in an ecosystem is unidirectional.
Reason (R): Energy captured by autotrophs does not revert back to solar input and is eventually lost as heat.
a) Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
b) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
c) Assertion (A) is true, but Reason (R) is false.
d) Assertion (A) is false, but Reason (R) is true.

photosynthesis definition:-Photosynthesis is the biochemical process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose or other organic molecules. This process occurs in the chloroplasts of plant cells and involves the utilization of carbon dioxide (CO2) from the atmosphere, water (H2O) taken up by the roots, and light energy absorbed by chlorophyll pigment molecules. Through a series of complex reactions, including the light-dependent and light-independent (Calvin cycle) reactions, photosynthesis produces oxygen (O2) as a byproduct and carbohydrates, such as glucose, which serve as energy sources for the organism. Photosynthesis is crucial for sustaining life on Earth as it is the primary means by which energy from the sun is converted into forms usable by living organisms.6CO2+6H2O+light energy→C6H12O6+6O2
In words, carbon dioxide (CO2) and water (H2O), in the presence of light energy, are converted into glucose (C6H12O6) and oxygen (O2). This equation represents the overall process of photosynthesis, encompassing both the light-dependent and light-independent reactions.
