Cycles of Matter, Part II
100
This type of organism uses carbon dioxide, water and sunlight to conduct photsynthesis.
What is a producer?
100
This type of consumer eats meat for its energy source.
What is carnivore?
100
A diagram that shows the movement of energy through an ecosystem.
What is a food chain or food web?
100
The continous process by which water moves from the Earth's surface to the atmosphere and back.
What is the water cycle?
100
These organisms take in carbon dioxide and release oxygen.
What are producers?
200
This type of organism cannot produce its own food, so it needs to obtain its energy from eating another organism.
What is a consumer?
200
This type of consumer uses plants as a source of energy.
What is herbivore?
200
A series of events in which one organism eats another and obtains energy.
What is a food chain?
200
The process by which a gas changes into a liquid.
What is condensation?
200
These organisms take in oxygen and release carbon dioxide.
What are consumers?
300
This type of organism is nature's recycler. It uses other organisms for energy and returns raw materials back into the ecosystem.
What is a decomposer?
300
This type of consumer uses plants and meat as a source of energy.
What is an omnivore?
300
A diagram which shows many overlapping food chains in an ecosystem.
What is a food web?
300
The process by which molecules of liquid water absorb energy and change into a gas.
What is evaporation?
300
This happens in the atmosphere when trees are burned to clear a forest.
What is an increase in carbon dioxide?
400
This carnivore uses the bodies of dead organisms as a source of energy.
What is a scavenger?
400
Humans are this type of consumer.
What is an omnivore?
400
It is possible for an organism to be a first level and a second level consumer in a food web. TRUE or FALSE
What is TRUE?
400
In this process, water vapor forms clouds and eventually returns water back to Earth.
What is precipitation?
400
In this process, free nitrogen is changed into a usable form of nitrogen.
What is nitrogen fixation?
500
This is the role humans play in the ecosystem.
What is a consumer?
500
This is determined by how an organism obtains energy and how it interacts with other organisms.
What is an organism's energy role?
500
This is the energy role of the first organism in a food chain.
What is a producer?
500
This is the source of energy that causes evaporation to begin.
What is the energy from the Sun?
500
These organisms are mostly responsible for combining nitrogen and other elements in the ecosystem.
What are bacteria?
