Transcript of Energy Flow

Energy Flow
Energy flow is the amount of energy that moves through a food chain.
The Trophic Pyramid
The trophic pyramid teaches us about energy transfer between levels of organisms.
Food Webs + Food Chains
Food webs show everything that and an animal eats, and what eats it.
Food chains only give a level-by-level graphical representation.
Food webs are much more complicated than food chains.
Terms to Know!
Ecology
Carnivore
Omnivore
Herbivore
Ecosystem
Recap:
Energy flow:
the amount of energy that moves through a food chain.
Ecology: the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
Energy Flow
There are five levels:
Producers
Primary Consumers
Secondary Consumers
Tertiary Consumers
Apex
(In order from bottom to top)
only 10% of energy is passed through each level.
Here is a food web:
These can help you figure out how populations would change in hypothetical situations:
For example, if the Red Eyed Tree Frog and Iguana died off, the insects population would increase
Carnivore: Eats only meat

Omnivore: Eats both plants and animals
Herbivore: eats only plants
Ecosystem: a biological community
of interacting organisms and their
physical environment.
The trophic Pyramid: It teaches us about
energy transfer between levels of organisms.
The five levels are:
Producers
Primary Consumers
Secondary Consumers
Tertiary Consumers
Apex
Only 10% of energy is passed
Food chains show everything one eats and everything that eats it.

Food chains only give a level-by-level graphical representation.
Food webs are much more complicated than
food chains.
Ecology: the branch of biology that deals
with the relations of organisms to one
another and to their physical
surroundings.
Also:
Omnivores- eat both meat and plants
Carnivores- eat just meat
Herbivores- eat just plants
