Heterotrophs
• Cannot synthesize organic
compounds from
inorganic precursors.
• Eat organisms from a
different population for
energy
• Liberating chemical-bond
energy for metabolic use
in glycolysis, Kreb’s cycle
and electron transport
chain
Example: Animals

4. Consumers
1. Herbivore
• Primary food source is

2. Carnivore
• Primary food source is
animal-based.
• Examples: vertebrates as
well as invertebrates
• Digestive systems is more
efficient in protein
digestion.

7. Consumers
2. Omnivore
• Primary food source is
both plant and animal-
based.
• Examples: human, bear,
cockroach, chicken
• Digest carbohydrates,
