Chris wrote a few steps to describe how carbon circulates between the ground and living organisms. Step 1. Plants absorb carbon dioxide in the air and use it to make their own food using photosynthesis.
Step 2. When plants or animals die, they are broken down by decomposers and their carbon returns to the soil.
Step 3. Carbon stays in the ground for long-term storage as fossilized carbon.

If step 1 is removed, which statement best describes the effects of this missing step on the carbon cycle?

not sure if this is what you'r looking for nnew= nold

geologic time scale (for gradpoint) =)

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
