Mo2-L2a: How Energy is Transferred?

Some producers make energy-rich compounds Omnivores eat producers and consumers and include

used to produce glucose. Carnivores eat herbivores, omnivores, and other
carnivores and include scorpions, octopuses, sharks,
tuna, frogs, insect-eating bats, moles, and owls

organisms and wastes produced by living organisms
and include termites, wood lice, and earthworms.
Consumers

Organisms that cannot make their own food are
consumers.

Consumers obtain energy and nutrients by
consuming other organisms or compounds
produced by other organisms.

Scavengers are detritivores that eat the bodies of
animals killed by carnivores or omnivores.

Herbivores eat producers and include butterflies, Examples of scavengers include hyenas, jackals, and
aphids, snails, mice, rabbits, fruit-eating bats, vultures.

The Flow of Energy
Once energy from the environment is converted into
food energy, it can be transferred to other organisms.

In an ecosystem, the food energy is transferred from
one organism to another through feeding
relationships.
