What is the role of photosynthesis in the flow of energy throughout an ecosystem?
A
It converts solar energy into chemical energy stored in glucose.
B
It absorbs energy from the breakdown of organic molecules.
C
It releases energy by breaking down glucose molecules.
D
It stores energy in the form of ATP for immediate use by plants.
Verified step by step guidance1
Understand that photosynthesis is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy in the form of glucose.
Recognize that the primary role of photosynthesis in an ecosystem is to capture solar energy and store it as chemical energy in glucose molecules, which can then be used by plants and other organisms as a source of energy.
Identify that during photosynthesis, carbon dioxide and water are converted into glucose and oxygen, using the energy from sunlight. This can be represented by the chemical equation:
Clarify that the glucose produced during photosynthesis serves as an energy source for plants and other organisms that consume plants, thus playing a crucial role in the energy flow within an ecosystem.
Note that while photosynthesis stores energy in glucose, it does not directly store energy in the form of ATP for immediate use; ATP is generated during cellular respiration, which occurs after glucose is metabolized.
