Question

fill in the blank answer on your answer sheet15. the equation for photosynthesis is: ____ + 6co₂ + light energy → 6o₂ + c₆h₁₂o₆.16. autotrophs are organisms that make their own food through ______.17. the equation for cellular respiration is: c₆h₁₂o₆ + 6o₂ → ______ + 6h₂o + energy.18. in the carbon cycle, plants absorb ______ from the atmosphere and release ______.19. what parts of the plant absorb○ co2 : ______○ h2o (liquid):______○ sunlight:________

Explanation:

1. Identified the missing reactant in the standard photosynthesis equation, which is water.
2. Stated the process autotrophs use to produce their own food, which is photosynthesis.
3. Identified the missing product in the standard cellular respiration equation, which is carbon dioxide.
4. Noted the key gas plants absorb and release in the carbon cycle.
5. Listed the specific plant parts that absorb each respective resource.

Answer:

1. $6H_2O$
2. photosynthesis
3. $6CO_2$
4. $\boldsymbol{CO_2}$; $\boldsymbol{O_2}$

19.

• CO2: Stomata (in leaves)
• H2O (liquid): Roots (root hairs)
• Sunlight: Chloroplasts (in leaves)
