producer
Any plant that makes its own food
consumer
An organism that eats other organisms
photosynthesis
the process and chemical reaction by which plants make their own food.
food chain
a diagram that shows a series of relationships between plants and animals that traces the path of energy and nutrients through an ecosystem
food web
many food chains interconnected
energy pyramid
a diagram that shows the amount of energy being lost in ecosystem
carnivore
An animal that eats other animals/meat
omnivore
An animal that eats both plants and animals
herbivore
An animal that eats only plants
Primary Consumer (1st level consumer)
Eats producer/herbivore
Secondary consumer (2nd level consumer)

Types of Decomposers
worm or mushroom
decompose

predator
Animal that kills and eats other animals
prey
Organism that is killed and eaten by a predator
decomposer
an organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients
energy pyramid
a diagram that shows the amount of energy that moves from one feeding level to another in a food web
food chain
a series of steps in which organisms transfer energy by eating and being eaten
food web
a system of interlocking and interdependent food chains
producer
an organism that can make its own food
trophic level
feeding positionin an ecosystem
consumer
an organism that obtains energy by feeding on other organisms
carnivore
a consumer that eats primarily animals
herbivore
a consumer that eats primarily plants
10% rule
Only 10% of the total energy produced at each trophic level is available to the next level. The amount of energy passed up to the levels of the food pyramid reduces as you go up.

Organism that makes their own food
Energy
the ability to do work
