How do plants obtain carbon pleas answer i need help

They use carbon to grow.

Explanation:

Plants use carbon dioxide during photosynthesis, the process whereby the plant converts the energy from the sun into a chemical carbohydrate molecule. Plants use this carbon chemical to grow. Once the plant's life cycle is over and it decomposes, carbon dioxide is formed again to return to the atmosphere and begin the cycle anew.

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy
