Energy Flow in
Ecosystems

Food chains: show the path of energy through trophic
(feeding) levels Energy come from the Energy is not recycled – it decreases and
is “lost” (made unavailable in the form of heat)

Level 1 - Producers Undergo
photosynthesis (plants, algae, some bacteria)
Use energy from the sun to make food (glucose)

Level 2 - Primary (1) Consumers Herbivores – eat plants

Level 3 – Secondary (2) Consumers Carnivores – eat meat Omnivores – eat
both meat and plants
Pygmy
Golden Headed Lion Tamarin
Margay

Detritivores - obtain energy from dead organisms at all trophic levels Decomposers –
cause decay Bacteria, fungi,
worms Rabbit
Scavengers – feed on the remains of dead organisms
snails, crabs, worms, raccoons, maggots, vultures, hyenas
Gecko

Food Web vs. Food Chain
What is the difference between a food chain and a food web?

Energy flow through ecosystems can be represented using a pyramid - why? 10% of the energy at each level is passed on to the next
level, 90% is used by heat and metabolism. Energy decreases as you move through trophic levels! It takes a lot of vegetation to support higher trophic
levels.
