Carbon
How do animals return carbon back to the atmosphere?
Cellular Respiration
What form of nitrogen makes up most of Earth’s atmosphere?
N2 Or Nitrogen Gas
Water moving across the land and not absorbing into the ground and moving down an mountain into a water source is what vocab term.
Runoff
Is phosphorus found in the atmosphere? (Yes or no)
No
How do animals get the nutrients they need to survive?
They eat it.
What process do plants use to remove carbon dioxide from the atmosphere?
Photosynthesis
Describe the Decomposers job in the Nitrogen Cycle.
Recycle nutrients back into the soil for other organisms.
Water leaving the plants and entering the atmosphere describes what vocab term?
Transpiration
What role does weathering play in the phosphorus cycle?
Weathering releases phosphorus from rocks into the soil and water
2 most common decomposers are...
Bacteria and Fungus
What 2 products are created at the end of Photosynthesis?
Glucose (sugar) and Oxygen
This natural occurring event, can change atmospheric Nitrogen into a usable form for plants to use. (Hint:happens in the sky)
Lightning
Water has cooled down and has transitioned from a gas state to a liquid state and formed clouds. What vocab term would reflect this whole process?
Condensation.
How do plants get phosphorus from the environment?
By absorbing it through their roots from the soil
Fertilizers add which 2 nutrients to the environment to increase the productivity of plants?
Nitrogen and Phosphorus
Which gas is released to the atmosphere during cellular respiration?
Carbon Dioxide or CO2
What organisms are incredibly important to getting Nitrogen into a usable form?
Nitrogen Fixing Bacteria
What part of the water cycle provides us with clean drinking water?
Infiltration or Percolation
Where is phosphorus mainly stored in the environment?
Rocks and soil (sedimentary rock)
How can excess nitrogen and/or phosphorus from fertilizers harm aquatic ecosystems?
It can cause eutrophication, algal blooms, low oxygen levels, and fish kills
How are fossil fuels stored underground?
Built up of dead organisms underground over millions of years with long period of time, high heat, and high pressure.
Earth's atmosphere is full of Nitrogen, what percentage of the atmosphere is Nitrogen?
78%
What is the driving force for the water cycle?
The sun
Why is phosphorus considered the longest biogeochemical cycle?
It takes a long amount of time for phosphorus to be buried before it is able to make it's way back up the mountain.
How does burning fossil fuels affect the carbon cycle?
Increases Carbon Dioxide in the atmosphere, contributing to climate change.
