Explanation:

1. Carbohydrates are food components used as quick - energy sources, so they match with F. Proteins provide muscle structure and function, matching with G. ATP is a substance present in all living things for energy transfer, matching with E. Chloroplast is an organelle only found in plant cells for photosynthesis, matching with B. Nucleic acids carry genetic information, no exact match in given options but conceptually important in living organisms. Photosynthesis is the process in which light is used to make glucose, matching with I. Lipids have the most energy per gram, matching with H. Respiration is the process in which oxygen is used to release energy, matching with J. Plants are organisms that remove CO₂ during photosynthesis, matching with C. Enzymes speed up reactions by lowering activation energy, matching with D.
2. All living things perform essential life functions such as acquiring matter and energy, reproducing, responding to stimuli, maintaining homeostasis, and evolving. So the answer is f.
3. Diatoms, like plants, perform photosynthesis where they use CO₂ and H₂O to produce glucose and O₂. So the answer is d.
4. Photosynthesis steps: Light - dependent reactions capture light energy and produce ATP and NADPH. Then in the Calvin cycle (light - independent reactions), CO₂ is fixed using ATP and NADPH to make glucose.
5. Cellular respiration steps: Glycolysis breaks down glucose into pyruvate, producing a small amount of ATP. Pyruvate is then used in the Krebs cycle to produce more ATP, NADH, and FADH₂. Finally, the electron - transport chain uses NADH and FADH₂ to produce a large amount of ATP using oxygen as the final electron acceptor.

Answer:

1. Carbohydrates - F, Proteins - G, ATP - E, Chloroplast - B, Nucleic Acids - (no perfect match), Photosynthesis - I, Lipids - H, Respiration - J, Plants - C, Enzymes - D
2. f
3. d
4. Light - dependent reactions produce ATP and NADPH; Calvin cycle fixes CO₂ to make glucose.
5. Glycolysis breaks glucose; Krebs cycle processes pyruvate; electron - transport chain produces ATP with oxygen as final acceptor.
