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).
Tide Pool Food Web
1. Draw lines to show energy movement in a food web for these 10 species.
2. Label each animal as:-Autotroph-Carnivores-Herbivores-Omnivores
