What is a producer
any animal that feeds mainly on plants; plant-eater
What is a herbivore?
Bears, humans, raccoons, many birds are this type of organism, based specifically on which foods they eat
What is an omnivore?
an organism that hunts, kills, and eats other organisms
What is a predator
A plant's source of energy
What is sun?
Where does all energy originate from?
the sun
Plants use this process to turn light into chemical energy
What is photosynthesis?
In a food web the mushroom and bacteria are....
What are decomposers?

What is an omnivore?
Where all organisms energy can be traced back to in a food web
What is the Sun?
Animals that only eat plants
What are herbivores?
If all the plants died in an ecosystem this would eventually happen to all the animals.
What is die also?
bacteria, fungi, worms, ants, beetles, sow bugs
What are some examples of decomposers?
Give three examples of abiotic components of an ecosystem
answers may vary (sun, water, dirt...)

Explain how an invasive species can effect an ecosystem
Answers may vary - overpopulation or loss of species
Organisms that come from somewhere else, but start to take over the natural ecosystem
