Why are trees important?

What happens if we cut them down?

Why should we replant them?

_______________

Essential for all life on Earth

Organisms take in carbon to help manufacture food (photosynthesis) or release carbon as part of respiration (breathing)

Constantly on the move through our environment.

When starting an aquarium, you can’t add fish right away… they’ll die. 

Why?

Keep this question in mind and we will revisit it at the end of class.

Nitrogen

Living things need Nitrogen. 

Earth’s atmosphere (____%) is Nitrogen.

Nitrogen also cycles through the biosphere.

______is the primary gas in the atmosphere

Nitrogen must be _________ before it is can be used by other organisms

Nitrogen is fixed by  __________ in the soil

Animals get nitrogen by eating ________

When those organisms are decomposed, the nitrogen is returned to the soil by __________

Nitrogen is vital for life on Earth. 

It is required for _________ and ______

Producers like plants can’t use the form of Nitrogen found in the atmosphere.

Nitrogen must combine with other elements first. 

This is done by bacteria  in the soil. It’s called “fixing” nitrogen. 

Plants can then absorb Nitrogen and start the process.

Which of the following is NOT a way that carbon returns to the atmosphere?

👍 volcanic eruptions

👎 burning of fossil fuels

✔ animal respiration

❌ photosynthesis by plants

Tuesday, February 4

Nitrogen is _____ by bacteria in the soil to make it usable for plants.

 👍 created

👎 made

 ✔  fixed

❌ removed

What other cycle is the phosphorus cycle connected to?

What are the 4 steps of the phosphorus cycle?

https://www.youtube.com/watch?v=Wzo-uFS7LUA&t=3s 

Essential to ____l living things

Necessary for the creation of DNA, bones, teeth, and cell membranes

Vital for food production - used in ____________

Cycles through the biosphere

What uses do we have for phosphorus?

_____________: Most phosphorus is found in rocks. Weathering extracts the phosphorus from the rocks and washes it into the soil.

___________ Phosphorus can be absorbed from the soil or water by plants. It can also be absorbed by animals from drinking water or eating plants. 

___________: When plants and animals die, they’re broken down and the phosphorus is returned to the soil. 

_____________ A natural supply of phosphorus that seeps into water over time.

_______   __________ Phosphate (in dead organisms) settles to the bottom of the water and is eventually formed in to new rocks. 

*The rock cycle takes thousands of years and eventually brings those rocks  to the surface.

Why do we need water? What do we use it for?

What percentage of Earth is water? 

Where is most of Earth’s water stored?

What steps of the water cycle did you see?
