Journal #12What must happen to nitrogen before

organisms can use it?What is the most abundant element in the

atmosphere?How does phosphorus enter the soil?

Today’s objectiveToday, we will continue making a flipbook to

provide a visual diagram of the 4 cycles we learned last week.

How to fold a flipbook:Fold the first page in half so that one side is

once inch shorter than the other.Take the second page and place it one inch

above the long side and fold along the same crease.

We will use 3 pages

Front page: Title PageCycles in Earth’s SystemDraw a picture related to the cycles we

learned about.

Page 2Nitrogen CycleYou will draw the nitrogen cycle and

describe what is taking placeDrawing must include at least 5 reservoirs

What is a reservoir?

Air

Bacteria in Soil

PlantsAnimals

Bacteria in Soil

Nitrogen CycleInclude Description:Nitrogen gas makes up 78% of

the atmosphereNitrogen must be fixed (by

bacteria or some plants) before plants and organisms can use it.

In the nitrogen cycle, nitrogen moves from air to soil, from soil to plants and animals and back to the air.

Page 3Label this tab: Phosphorus CycleDraw a diagram of the phosphorus and

include5 reservoirsDescriptions of how phosphorus moves

from one reservoir to the next. (see next slide)

Information to IncludePhosphorous is rarely a gasPhosphorous enters the soil and water when rock

breaks down and when phosphorus dissolves in water

Some organisms excrete excess phosphorus in their waste, and this phosphorus may enter soil and water.

Plants absorb this phosphorus through their roots.Animals absorb phosphorus when they eat plants.When animals die, the phosphorus returns to the

environment through decomposition

Journal #131. What is transpiration?

2. Carbon is stored in the geosphere in buried plant or animal remains and a rock type called___.

Page 4- Carbon CycleLabel this tab Carbon CycleDraw a diagram of the carbon cycle and

include arrows showing direction of energy flow.

Include 5 reservoirs in your drawingWrite a description of the carbon cycle (see

next slide)

Page 4- Carbon Cycle DescriptionCarbon moves through all 4 spheres Plants convert Carbon Dioxide into sugarOrganisms eat the plants, and obtain carbon

from the sugar and release carbon into the air as carbon dioxide, wastes and decay

Carbon is stored in the geosphere in buried plant or animal remains and rock called carbonate

Page 5 –Water CycleLabel this tab Water CycleDraw a diagram of the water cycle and

include arrows showing direction of energy flow.

Include 5 reservoirs in your drawingWrite a description of the water cycle (see

next slide)

Page 5- Water Cycle DescriptionThe movement of water from the atmosphere

to Earth’s surface and back to the atmosphere is always taking place.

Transpiration is the release of moisture from plant leaves.

Continuous movement of water is called the water cycle
