Chapter 2-3 ContinuedNutrient Cycle

The Water CycleEvaporation: water is converted from its

liquid form to its vapor form and transferred from land and to the atmosphere

Condensation: the change of water from its gaseous form (water vapor) into liquid water

Precipitation: water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.

Run-off: the flow of water, from rain, snowmelt, or other sources, over land

Transpiration: evaporation of water from plants

The Water Cycle

Photosynthesis, energy from the sun is used to convert carbon dioxide to food by plants

Respiration, animals take in oxygen and release carbon dioxide

The Carbon Cycle

The Carbon Cycle

-Over millions of years it turns into fossil fuels-Fossil fuels=used for driving cars releases carbon into the atmosphere-Open burnings also release carbon into the atmosphere

The Nitrogen Cycle

Plants and animals can’t use Nitrogen gas from the air

Nitrogen-fixing bacteria convert gas to ammonia and place in soil

The Nitrogen Cycle1. Nitrogen is in the air. Bacteria in soil take

it from the air and put it in the soil. (Nitrogen-fixing)

2. Autotrophs then use the nitrogen to grow.3. Heterotrophs eat the autotroph and get

nitrogen.4. Decomposers (bacteria) breakdown

urine/decomposing tissues from organisms releasing nitrogen

5. It is released for plants to use and into the atmosphere

The Phosphorus CyclePhosphorus is rarely

a gas, so it can’t cycle through the atmosphere.

Animals- eat plants

Water- absorbed from the soil

and rocks

Plants- get phosphorus from

water

Soil and rocks- absorbed from

dead plants and animal waste

Part 1: Add 100ml to the glass beaker and put it on the hot plate. Turn the hot plate on to 150 Celsius. Cover your beaker with aluminum foil and observe.

Part 2: Obtain 100 ml of flour and add 35 ml of color water to it. Mix well and create a modelof the Earth’s interior layers

Clean up procedure: Make sure nothing go in the sink (all dough go in the trash can).

Answer These Questions in Complete Sentences1. List the (autotroph) producers in the tide

pool2. Which species cannot move and attached

itself to rocks? 3. Which species is camouflaged in the tide

pool? How can camouflage help them?4. Which intertidal zone can we expect to find

mussels?5. How can humans hurt or help the tide pool? 6. Draw a picture of sea urchin(s)
