Monday 11/28/2016 What is one thing that frightens you about finals? What can you do to get a better grade besides study? What was one of the greatest parts of your thanksgiving break? (please don’t say sleep)

25.2 KEY CONCEPT Matter cycles in and out of an ecosystem.

Water cycles through the environment. The hydrologic, or water cycle, is the circular pathway of water on Earth. Organisms all have bodies made mostly of water. precipitation condensation transpiration evaporation water storage in ocean surface runoff lake groundwater seepage

As students watch the video, they will take notes looking for: Water cycle As students watch the video, they will take notes looking for: 1. The three states of water: liquid, solid, gas. 2. Definition of the terms: evaporation, runoff, seepage, transpiration, condensation, precipitation https://www.youtube.com/watch?v=al-do-HGuIk#action=share

Why do you think the water cycle is so important to us? Be specific! Tuesday 11/29/2016 Before you finish the first question, start downloading the free app on your phone: “stop motion studio”. Why do you think the water cycle is so important to us? Be specific!

Things needed in your stop motion video for full credit: Water shown at least once in all three states: Liquid Solid Gas All of these words need to be used in your video at least once: Seepage Runoff Evaporation Condensation Precipitation Transpiration Groundwater

What are some sources of carbon on earth? Wednesday 11/30/2016 What are some sources of carbon on earth? Explain what seepage is and how it relates to water.

Elements essential for life also cycle through ecosystems. A biogeochemical cycle is the movement of a particular chemical through the biological and geological parts of an ecosystem.

Oxygen cycles indirectly through an ecosystem by the cycling of other nutrients. respiration carbon dioxide photosynthesis

Carbon is the building block of life. Carbon cycle moves carbon from the atmosphere, through the food web, and returns to the atmosphere. Fossil fuels (oil, gas) emit carbon back into the atmosphere fossil fuels photosynthesis decomposition of organisms respiration carbon dioxide in air combustion

NITROGEN CYCLE Takes place primarily underground

Nitrogen fixation: nitrogen gas (N2) ammonia (NH3) Bacteria will “fix” or “change” it into a usable form for plants - bacteria live freely in soil or - on nodules of roots of some plants such as beans and peas (legumes) Nitrogen gas (N2) converted  Ammonia (NH3)  converted to Ammonium (NH4)  energy source for bacteria

Nitrification Bacteria change ammonium  Nitrates NO3-  taken up by plants  convert to Proteins -Denitrifying bacteria use nitrates as a source of oxygen  release nitrogen gas BACK into atmosphere

Atmospheric Nitrogen fixation Lightening breaks apart nitrogen molecules

Ammonification: Role of Bacterial Decomposers Decomposers break down Animal excretions Dead animals or plants Nitrogen from this matter  returned to soil as ammonium

animals nitrifying bacteria ammonium plant nitrogen-fixing bacteria in soil nitrates nitrites

Nitrifying bacteria change the ammonium into nitrate . Ammonia released into the soil is transformed into ammonium (Ammonification). Nitrifying bacteria change the ammonium into nitrate . Nitrogen moves through the food web and returns to the soil during decomposition. nitrogen in atmosphere animals denitrifying bacteria nitrifying ammonium ammonification decomposers plant nitrogen-fixing bacteria in soil bacteria in roots nitrates nitrites

What are some sources of nitrogen on Earth? Thursday 12/3/2015 What are some sources of nitrogen on Earth? What is nitrification? What is nitrogen fixing?

Think! Turn and talk to your partner to answer! Where does the source of nitrogen come from for animals? Where does the source of nitrogen come from for plants? What form of nitrogen do plants commonly use? What is nitrogen fixation? Why might farmers use legumes such as peas to improve the nitrogen levels in their soil? Plant matter 2. decomposers, bacteria 3. nitrates 4. The process that changes N-gas into a usable form for plant material 5. Legumes have nodules containing nitrogen-fixing bacteria which can increase N-levels in the soil without adding fertilizer

What are the two main processes used in the Carbon- Oxygen cycle? After watching the videos and taking notes, create a T-Chart and list the sources of carbon and oxygen to show how they are each cycled through the environment. Collaborate with your partner!

Friday 12/2/2016 Write down each letter and label/describe the step. What step is missing that is similar to A?

Carbon Cycle Nitrogen Cycle Make sure you show all the steps including: At least 3 different types of combustion At least 2 different sources of respiration Two different plants using photosynthesis Explain and show how fossil fuels contribute to the cycle Nitrogen Cycle Make sure you show all the steps including: Animal excretions returning to the soil An animal/plant decaying and returning N to the soil The entire underground and atmospheric process of nitrogen Make sure you show the bacteria needed at each step to make that change.

What form of nitrogen do plants commonly use? Monday 12/5/2016 Where does the source of nitrogen come from for animals? How about for plants? What form of nitrogen do plants commonly use?

Carbon Cycle Nitrogen Cycle Make sure you show all the steps including: At least 3 different types of combustion At least 2 different sources of respiration Two different plants using photosynthesis Explain and show how fossil fuels contribute to the cycle Nitrogen Cycle Make sure you show all the steps including: Animal excretions returning to the soil An animal/plant decaying and returning N to the soil The entire underground and atmospheric process of nitrogen Make sure you show the bacteria needed at each step to make that change.

Name three forms that nitrogen takes on during the nitrogen cycle. Tuesday 12/6/2016 What is a biogeochemical cycle? Why is it important to us here on Earth? Name three forms that nitrogen takes on during the nitrogen cycle.

Draw the water cycle and include all of the steps. Get out a lined piece of paper! Draw the water cycle and include all of the steps. How are respiration and photosynthesis related? Why do they need one another? Explain where animals get carbon from. What are fossil fuels? How do they relate to the carbon cycle?

What cycle is this? Justify your answer! Describe what each letter represents. A B D C

What is nitrification? Why is it so important? Where does most of the nitrogen cycle take place? Which organism helps move this cycle along?
