Answer:
<h3>Plants need oxygen because plants are made living cells which need to perform cellular respiration to get the energy they need to function. Admittedly, needing to perform cellular respiration alone does not mean that consuming oxygen is required - many (micro)organisms use fermentation or anaerobic respiration.</h3>
One claim that supports one law of thermodynamics in photosynthesis is that energy is conserved, but the form of energy changes (Law 1).
<h3>What is photosynthesis?</h3>
Photosynthesis is a process done by plants and other organisms to obtain energy. This process implies a set of reactions that aim at converting light energy into chemical energy the organisms can use.
<h3>How is photosynthesis related to thermodynamics?</h3>
One way photosynthesis supports the laws of thermodynamics is through the first law that establishes energy is conserved, but the form of the energy can change.
This is because, in photosynthesis, the initial solar energy is transformed into chemical energy by storing the energy in carbon-hydrogen chemical bonds. This means the form of energy has changed but the energy is preserved.
Note: This question is incomplete because the graph is not given; due to this, I answered it based on general knowledge.
