A simple way of describing how energy is transferred from organism to organism
100
Define and identify a producer.
Any plant - makes its own food
100
What diagram shows how energy is passed from level to level in a food web?
Energy pyramid
100
What does the word photosynthesis mean?
Light/put together
100
All food chains begin with a __________.
Producer
200
What is a producer?
A plant because it makes its own food
200
Define and identify a herbivore.
Plant eater - Rabbit,caribou, ox, etc.
200
Why does the number of organisms decrease as you move up an energy pyramid?
Organisms need most of their energy for life processes (less energy is being passed, so less organisms at next level)
200
Where does photosynthesis take place?
In the chloroplasts of leaves (MUST be in green part of a plant)
200
In which way do the arrows go in a food web? (do not answer left, right, up, or down!)
In the flow of energy
300
What is the name of an animal that eats dead and/or rotting organisms? Give an example.
A scavenger - coyote
300
What is the difference between an herbivore, carnivore, and omnivore?
Herbivores eat only plants; carnivores eat only meats; and omnivores eat either
300
What is the difference between a food chain and a food web?
A food chain is one part of a food web; it follows one organism's food; a food web is a combination of many food chains
300
What does the plant take in during photosynthesis?
Water, carbon dioxide, energy from the sun, also nutrients
300
What the name of the simple sugar produced during photosynthesis?
Glucose
400
What is a decomposer? Give an example.
Decomposers break down dead organisms and return nutrients to the soil. Examples: ants, worms, beetles, bacteria, etc.
400
Name a secondary (second level) consumer and why it would be a secondary consumer.
Bird;cat;owl;fox,etc. because it eats animals that eat producers
400
Describe how an organism can be at different levels of a food chain. Give an example.
Can be first, second, or third level consumer: example would be a human eating plants, or herbivores, or carnivores
400
What does the plant give off as a WASTE product?
Oxygen
400
What pigment found in a plant is responsible for absorbing sunlight during photosynthesis?
Chlorophyll
500
What is the definition of an ecosystem? Give an example.
A community of organisms and their nonliving environment. Examples: prairie, desert, polar region, etc.
500
What 2 things would happen if the squirrel population decreased?
More acorns, corn, etc. and the number of predators would decrease
500
Give an example of something in an ecosystem that is not alive and why it is important for that particular ecosystem.
Rocks, stones, dirt, water; etc.
500
Write the equation for photosynthesis.
Water + Carbon Dioxide + Energy from the sun (+ nutrients) = Sugar + Oxygen
500
Name one way plants depend upon animals and animals depend upon plants for their basic needs.
Example: plants provide oxygen for animals to breathe, animals provide carbon dioxide for plants to undergo photosynthesis and make food for themselves
