 Food chains

show the flow of energy in the ecosystem

Producer or Autotroph

an organism that makes its own food like a plant

Consumer or Heterotroph

an organism that has to eat

Herbivore

eats only plants ex

Primary Consumer

1st thing to eat (a herbivore)

Secondary Consumer

eats animals that something else has killed ex

Decomposer

breaks down dead material

 Niche

the job or role an organism has in its ecosystem or how it makes a living Ex

 Habitat

where an organism lives

Environmental problems

Humans are responsible for almost all modern day environmental issues

 Habitat Destruction

destroying the home of an organism

 Biodiversity

having many types of living things

 Bioaccumulation or Biomagnification

when poisons build up in the food chain

 Acid Rain

this is rain that has a pH of less than 7

 Ozone Layer

Ozone is a layer of gases which filters out the harmful UV

 Nonnative or invasive species

these are organisms which are from another

 Stewardship and Sustainable practices

when humans work to protect their

Commensalism

 one organism benefits and the other doesnt care (not

hurt or helped) Example

a cow walking in a field stirs up insects for the cow bird to eat

Carbon Cycle

Carbon is an element that is in all living things on earth

 Three ways Carbon Dioxide gets into the atmosphere

respiration, burning fossil fuels, and open burning

 The main way Carbon is removed from the atmosphere is

Photosynthesis
