In the context of organic chemistry and biological systems, what is the original source of energy in a food chain?
A
Sunlight
B
Heat from the Earth's core
C
Chemical bonds in glucose
D
ATP molecules
Verified step by step guidance1
Understand that in most ecosystems, the primary source of energy is the sun. This energy is captured by plants through the process of photosynthesis.
Recognize that during photosynthesis, plants convert sunlight into chemical energy stored in glucose molecules. This is the basis for energy flow in a food chain.
Identify that glucose, a simple sugar, is used by plants and other organisms to produce ATP (adenosine triphosphate) through cellular respiration, which is the energy currency of cells.
Acknowledge that while ATP molecules and chemical bonds in glucose are forms of stored energy, they are not the original source. They are intermediates in the energy transfer process.
Conclude that the original source of energy in a food chain is sunlight, as it initiates the conversion of solar energy into chemical energy by producers (plants).
