Food Chain
A single, linear path showing the flow of energy from the sun to producer and through different levels of consumers.
Food chain
Overlapping food chains with different pathways for the flow of food energy in an ecosystem.
Food web
Animals that eat other animals that eat plants.
Secondary consumer
A diagram that shows the trophic levels of organisms in a food web.
Energy pyramid
Stages in the food chain. (consist of organism doing a role)
Trophic level
phytoplankton to zooplankton to herring to salmon. the zooplankton in this food chain are
Primary consumers
How are food webs arranged into trophic levels?
primary producers at the bottom, herbivores in the middle, and carnivores at the top.
Organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion.
Decomposer
What level will contain plants
1/ primary producer
Only ——% 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.
10%
Arrows in a food chain represent the
Flow of energy
The relationship between a predator and prey is best illustrated by:
a. a zebra eating grass
b. a snake eating a mouse
c. a vulture eating road kill
d. a fish eating a bird
B
An organism that gets their energy by feeding on producers in the food chain.
Primary consumer
A third-level consumer has to be which type?
A carnivore / tertiary consumer
What is a habitat?
The place where an organism lives
What do all food webs energy come from
The sun
How are food webs different to food chains?
a. Shows Whole ecosystem
b. Less information
c. More colorful
A
Organisms that make complex, energy-containing biomolecules from simple inorganic molecules using energy captured from light or inorganic chemical compounds.
Producer
A secondary consumer eats —
Primary consumers
an autotroph is when a organism
Makes its own food
If a species goes extinct the entire food web will
Be affected/ or die
The algae at the bottom of the food web are
Producers
Animals that eat secondary consumers
tertiary consumer
Why are there usually few organisms at the top of an energy pyramid?
So much energy is lost from one level to another that the energy available can only support few organisms
What is the fifth level in an energy pyramid
Quarternary
