What gets energy by eating producers and/or consumers?
A consumer.
100
True or False: Humans add nitrogen and phosphorus to the cycle by using fertilizer.
True.
100
What is the definition of "carbon cycle"?
A process in which carbon is cycled between the atmosphere, land, water, and organisms.
100
True or False: Primary succession is caused by natural disasters.
False.
100
Where does secondary succession occur?
On a surface where there was already an ecosystem.
200
What is the difference between a food chain and a food web?
A food web is more complex.
200
Consumers get nitrogen by doing what?
Eating and drinking.
200
Where is one place that carbon is stored?
Oceans Plants Limestone Fossil Fuels
200
What is the difference between secondary and primary succession?
Primary occurs where there has never been an ecosystem, secondary has had an ecosystem there before.
200
Secondary succession occurs more quickly than __________ ___________ because there was already an ecosystem in place.
Primary succession.
300
What is the transfer of energy through steps in the food chain called?
Trophic level.
300
How do humans add nitrogen or phosphorus to the ground or air?
By using fertilizer.
300
Too much carbon in the atmosphere can lead to ________ _________.
Global warming
300
What is the first organism that starts primary succession? Name the specific pioneer species.
Lichens
300
Why does secondary succession occur faster than the other type?
Because there was already an ecosystem there.
400
Give an example of a food chain.
Answers will vary, but should include at least 4 organisms.
400
What do all organisms need to build proteins?
Nitrogen.
400
What type of organism takes in carbon from the carbon cycle?
Producers
400
A lichen is a cross between which two kingdoms?
Fungi and algae (or plant)
400
Give 2 examples of why fires are beneficial.
It helps clear dead plants and helps spread seeds.
500
Make a food chain and turn it into a food web.
Answers may vary, but should contain multiple arrows- all of which point at the predator.
500
What are two things that these two cycles have in common?
They both can be added to by using fertilizer. Organisms eat other organisms to gain these minerals.
500
Explain how humans add and remove carbon from the cycle? How does nature add and remove carbon from the cycle?
Humans add by breathing and burning fossil fuels. They remove by planting trees. Nature adds through volcanic eruptions and forest fires. Nature removes by supporting producers.
500
Explain how primary and old field succession are alike.
Both do NOT require a natural disaster.
500
Describe 4 examples of what happens during secondary succession.
1. Natural disaster (as long as you're not talking Old Field) 2. Pioneer species grow. 3. Small plants replace pioneer species. 4. Larger plants, shrubs, and trees replace small plants.
