Which of the following is true of carbon?
Carbon is present in all organisms and in the atmosphere.*
Carbon moves from consumers to producers.
Carbon must be fixed by bacteria before other organisms can use it.
Carbon can only be released from dead organisms by decomposers.
I'm pretty sure that's right!
(Yea I know this is 3 years late)
whats the aswer
The correct statement among the given options is: Carbon is present in all organisms and in the atmosphere.
The correct answer is: Carbon is present in all organisms and in the atmosphere.
To determine the correct answer, we can go through each option and eliminate the false statements:
1. Carbon is present in all organisms and in the atmosphere: This statement is true. Carbon is an essential element found in all living organisms, including plants, animals, and microorganisms. It is also present in the atmosphere in the form of carbon dioxide (CO2).
2. Carbon moves from consumers to producers: This statement is incorrect. Carbon actually moves from producers (plants) to consumers (animals) in the form of food and energy. Producers, through photosynthesis, convert carbon dioxide into organic compounds like glucose, which is then consumed by consumers.
3. Carbon must be fixed by bacteria before other organisms can use it: This statement is partially true. While carbon can be directly utilized by some organisms, such as plants during photosynthesis, certain bacteria play a vital role in fixing carbon. These bacteria convert atmospheric nitrogen into forms that can be used by other organisms.
4. Carbon can only be released from dead organisms by decomposers: This statement is false. Carbon is continuously cycled in the environment through various processes such as respiration, combustion, and decomposition. While decomposers (like fungi and bacteria) do play a significant role in breaking down organic matter and releasing carbon back into the environment, carbon can also be released through other means, such as respiration by living organisms and combustion of fossil fuels.
Therefore, option 1 is the correct answer as it accurately states that carbon is present in all organisms and in the atmosphere.
