Question

carbon moves from the biosphere to the atmosphere via cellular respiration. carbon moves from the biosphere to the atmosphere via decomposition. carbon moves from the atmosphere to the biosphere via photosynthesis. carbon moves within the biosphere from an autotroph to a heterotroph. carbon moves within the biosphere from a heterotroph to another heterotroph. step 1: bacteria decompose a frogs dead body in a swamp and release carbon dioxide gas into the air. step 2: aquatic algae absorb carbon dioxide from the air. the algae use the carbon dioxide to produce glucose. step 3: a small fish consumes algae in the water. the fish stores glucose from the algae in its liver as a complex carbohydrate called glycogen. step 4: the fish is eaten by an alligator. the alligator digests the body of the fish to obtain nutrients and energy. step 5: the alligator exhales carbon dioxide from its lungs into the air.

Explanation:

Step 1 shows carbon moving from biosphere to atmosphere via decomposition. Step 2 shows carbon moving from atmosphere to biosphere via photosynthesis. Step 3 shows carbon moving within biosphere from autotroph (algae) to heterotroph (fish). Step 4 shows carbon moving within biosphere from one heterotroph (fish) to another (alligator). Step 5 shows carbon moving from biosphere to atmosphere via cellular respiration.

Answer:

Step 1: Carbon moves from the biosphere to the atmosphere via decomposition.
Step 2: Carbon moves from the atmosphere to the biosphere via photosynthesis.
Step 3: Carbon moves within the biosphere from an autotroph to a heterotroph.
Step 4: Carbon moves within the biosphere from a heterotroph to another heterotroph.
Step 5: Carbon moves from the biosphere to the atmosphere via cellular respiration.
