A student is drawing a model of the carbon cycle. Which caption should he include to explain how herbivores contribute to the carbon cycle from the food they eat?

Answers

Answer:

Cellular respiration

Explanation:

Herbivores are organisms that feed on plant materials solely. They are usually animals like sheep, cattle, goats with four stomach compartments. They are part of the global carbon cycle which shows how carbon is circulated in nature.

  • Plant matter is broken down by herbivores through a series of metabolic steps.
  • The final product is a glucose laden material which is the raw material needed for cellular respiration.
  • When oxygen combines with the glucose, energy is liberated, and carbon dioxide, a waste product is released into the atmosphere.
  • This way, carbon is cycled in the ecosystem.

Answer:

Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.
