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.
In facilitated diffusion molecules only move with the aid of a protein in the membrane. Normal diffusion requires molecules to move through a special doorway
