Carbon dioxide, water, sun
Who is eating who?
Snake --> hawk
What is a decomposer? Why are they important to our Earth?
They are an organism that breaks things down...Earthworms, bacteria etc. If we didn't have them we wouldn't have nutrient-rich soil, and there would be a lot of dead matter.
True or false: matter and energy are created and destroyed.
FALSE: they are always present in the same amounts, just recycled over and over.
Define herbivore and carnivore
an animal that only eats plants
an animal that only eats meat

When drawing a food web, what always goes on the bottom or what is the organism that starts it?
PLANTS! Producers!
What is a consumer?
Something that "consumes" other things...or eats.
Explain how a dead animal can contribute to the carbon cycle and eventually put carbon into the air.
Animal dies...carbon goes into soil...then goes into a plant...an animal eats it...that animal breathes carbon out. **Answers vary.

In an ecosystem, are there more plants or more animals? Could an ecosystem survive without plants?
More plants! They have the most energy (from the sun)! NO--nothing would be functioning without plants.
300 kcals will be available because 10% of energy is passed on to each thing eating the plant...10% of 3000 is 300.
What is a tertiary consumer?
An animal that eats secondary consumers.
What is a community? Give an example
Multiple populations together...3 deer and 4 squirrels in a forest
What does biotic mean? Give an example
A living thing...deer, rabbit, flower etc
What are the animals called that eat primary producers?
Primary consumers
How much energy is passed on from each trophic level to another?
10% 10% 10%!!!!
What is a population?
Multiple of the same type of organism
What is an ecosystem?
All of the living and nonliving things together in their environment
