Tertiary Cons.Scavengers
* * Decomposer⇒ "breaks down" the remains of once livingorganism & returns the nutrients back to the soil
90%of all energy on each tropic level is used by theorganism to maintain life
10% of all energy is available to the next tropic level& is stored in the tissue of the organism

Food Chain‐ diagram that shows the flow of energy of food molecules from one
organisms to the next
Food Web‐ diagram that shows the flow if energy of from organism to the next
in an actual environment or ecosystem; several food chains connected together
Energy Pyramid‐ shows how the flow of energy moves through a food chain;
energy is lost as it moves up the pyramid
kilo calories‐ 1,000 small calories; the energy producing potential in food
trophic levels‐ the position an organism occupies in a food chain
habitat ‐ a place where an organism lives
niche‐ the role or job an organism plays in its habitat
How do organisms use energy?
walking, talking, growing, breathing, (any daily life processes)
What would happen if an organism did not have a source of energy?
the organism would not survive
