Can plants and animals use nitrogen from the air: Yes or no?
(a)
Which of these include the hydrosphere?
Excess nitrates getting washed out into ground water
Nitrogen being fixed by nitrogen fixing bacteria into usable nitrates
Fungi decomposing dead animal material
Lightning converting nitrates back to nitrogen gas
How do plants and animals get nitrogen?
Directly from the air
From decomposers converting dead material into ammonia
From nitrogen fixing bacteria converting nitrogen into nitrates
From plants taking it up through its roots
Is nitrogen deadly to fish?
No, they need it to function
Yes, even a little is lethal
No, it doesn't bother them
Yes, but only at high levels
Where is carbon stored?
In the oceans
In the ground as fossil fuels
In living things
All of these
How does carbon affect the oceans?
It increases the pH
It turns into carbonic acid
It lowers the pH
It increases fish growth
What are the products of photosynthesis?
Glucose
Carbon Dioxide
Oxygen
Water
How is nitrogen removed from the atmosphere?
Nitrogen Fixing bacteria
Burning fossil fuels
Plants taking in nitrogen gas
Animals taking in nitrogen gas
What is the proper sequence for the nitrogen cycle?
Nitrogen gas - nitrates - nitrites - ammonia
Nitrites - nitrates - nitrogen gas - ammonia
nitrates - nitrogen gas - ammonia - nitrites
nitrogen gas - ammonia - nitrites - nitrates
Which is a false statement?
Humans make carbon dioxide
Greenhouse gasses are harmful in any quantity

Plants take in carbon dioxide
Which of these is NOT a greenhouse gas?
Nitrogen gas
Methane
Carbon dioxide
Water vapor
What is the definition for global warming?

The natural cooling of the Earth
Electricity and Transportation produce the most greenhouse gases
True
False
Which isn't a result of global warming?
Higher than average temperatures
Hotter summers
Colder summers

How does the greenhouse effect work?
Heat from the sun gets stuck due to gravity
