Energy starts with the sun and is passed through many food
chains. Each time it is passed along, the energy gets smaller
and smaller.

Food Web – a group of food chains linked together
Producers – organisms that produce/make their own food
Consumers – organisms that eat/consume other living things
Herbivores – Plant eaters
Carnivores– Meat eaters
Alien Species – Organisms brought into a new environment
that may affect food webs
Competition – The struggle among organisms for something
they need
Energy pyramid – Shows the amount of energy at each stage
of the food chain

Remember:
-Animals may compete for water, sunlight, food, and a mate
-An example of an alien species is a cane frog brought from
S. America to Australia to eat the beetles (it didn’t work!)
-Examples of alien species in MS: nutria and boll weevil bugs
- A lot of energy gets used at each level of the food chain
so only a fraction (1/10th) can be passed on.
- Most producers are plants that make their food from
photosynthesis
- Consumers include insects, birds, mammals, fish, reptiles,
and even humans!
