Question

all living things contain carbon. do organisms make their own carbon? * 1 point
○ yes, carbon is created during cellular respiration.
○ yes, carbon is created in plants and other photoautotrophs during photosynthesis.
○ no, carbon is cycled through different interactions, however, it is not created or destroyed.
○ no, additional carbon is routinely added to the planet from space as needed
true or false * 1 point
photosynthesis removes carbon dioxide from the atmosphere and uses it to make organic compounds.
○ true
○ false

Explanation:

For the first question: The law of conservation of mass states matter (including carbon) is not created or destroyed, only cycled between organisms and the environment. Cellular respiration and photosynthesis rearrange carbon, not create it, and carbon is not routinely added from space.
For the second question: The core function of photosynthesis in photoautotrophs is to take in atmospheric carbon dioxide and convert it into organic carbon compounds like glucose.

Answer:

1. No, carbon is cycled through different interactions, however, it is not created or destroyed.
2. True
