Consumers
200
Animals that eat ONLY other animals
Carnivores
200
A food chain ALWAYS begins with__________
Producer
200
All plants and animals in an ecosystem make up a ____________
Community
200
Something that shows how ALL the animals in a COMMUNITY get their energy (food)
Food web
300
These are the lowest on the energy pyramid and have the most energy.
Producers
300
Animals that eat BOTH plants and animals
Omnivores
300
If producers died out, what would happen to the food chain? Why?
The whole thing would fail because producers provide the energy.
300
One species of an animal in a community is considered a
Population
300

What are the four ways energy is used?

1. Movement

2. Warmth

3. Growth

4. Body Repair. 

400
Water, Sunlight, and Carbon Dioxide are what kind of environmental factors? Why?
Abiotic because they are nonliving and have never been living.
400
The top of the energy pyramid belongs to what kind of organism?
Carnivores/omnivores that eat carnivores
400
What would happen to a food chain if the top carnivore died out?
The level below would overpopulate, causing the food to diminish. This would disrupt the whole food chain and cause many organisms to suffer.
400
The most important biotic factor in a food web is: A. Sun B. Producers C. Herbivores D. Carnivores
B. Producers
400

Name 4 biotic and 4 abiotic factors.

Ask Mr. C.

500
Where does most of the energy go in the course of a food web or energy pyramid?
Lost to environment as heat
500
Explain how a food web works in terms of energy.
The producers have the most and make their food from the sun. The herbivores eat the producers and get 90% less energy. The carnivores eat the herbivores and get 90% energy. The larger carnivores eat other carnivores and get the 90% less energy again, getting the least. Most energy is lost as heat.
500
What abiotic factor is most important in the food chain? A. Water B. Carbon Dioxide C. Sun D. Producers
C. Sun
500
Why is a food web so complicated?
Because many organisms share predator/prey relationships and are interconnected.
500

Where do Plants (Producers) get their mass from?

What is Air & Water?
