1 I Can Statement Conversation/Assignment H.B.6B. Conceptual Understanding: Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged between the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes. H.B.6B.1 Develop and use models of the carbon cycle, which include the interactions between photosynthesis, cellular respiration and other processes that release carbon dioxide, to evaluate the effects of increasing atmospheric carbon dioxide on natural and agricultural ecosystems. I can... illustrate the flow of energy and cycling of matter through an ecosystem. model and explain the carbon cycle including photosynthesis, cellular respiration, and other processes that release carbon dioxide. explain how increasing carbon dioxide levels affect natural and agricultural ecosystems. All living systems need matter and energy. As energy and matter flow through an ecosystem, matter must be recycled and reused. The cycling of matter and the flow of energy within ecosystems occur through interactions among different organisms and between organisms and the physical environment. The biosphere contains three parts, describe them below and indicate how carbon is stored in the location: Location Description of location How is carbon stored here? Atmosphere Geosphere Hydrosphere Identify and create a diagram below explaining the two main ways that carbon is cycled through the biosphere by biotic factors. To the left are CO 2 levels in the atmosphere. Interpret and construct an explanation for the graph.

2 Amount of CO 2 in the atmosphere Greenhouse effect Average Global Temperature Plant cover on Earth Rate of photosynthesis Amount of CO 2 absorbed by plants Amount of CO 2 in the atmosphere higher increases increases Increases increases Increases decreases lower decreases decreases decreases decreases Decreases increases What are the effects of increasing atmospheric carbon dioxide? Based on the above chart, identify the cause of increase in global temperature. Label the following processes on the diagram of the Carbon Cycle to the right: photosynthesis cellular respiration decomposition What is the process where carbon dioxide is released from animals and plants? Plants take in carbon dioxide and release oxygen through a process called. When organisms die, decomposers break down carbon compounds that are eventually released into the atmosphere as carbon dioxide. What is this process called?

3 I can illustrate the flow of energy and cycling of matter through an ecosystem. model and explain the water cycle and nitrogen cycle. The Nitrogen Cycle The matter in the air is made up of 78% nitrogen, 21% oxygen, 0.93% argon, and 0.039% carbon dioxide. How does nitrogen enter the food cycle when plants and animals only utilize the oxygen and carbon dioxide from the air? After identifying how, use the following in explanation: N 2, plants, animals, ammonia, food chain Describe the difference in nitrogen fixation and denitrification. Also, why is nitrogen essential for living things? How is nitrogen returned to the atmosphere? The biosphere contains three parts, describe them below and how nitrogen is stored in the location: Location Description of location How is nitrogen stored here? Atmosphere Geosphere

4 The Water Cycle What drives the water cycle? Fill in the blank: condensation. transpiration evaporation. precipitation. During, water molecules in liquid state escapes into the air as water vapor. Any form of water that falls from clouds and reaches Earth s surface is called. Molecules of water vapor in the air become liquid water:. Plants lose water through their leaves through a process called. Location Description of location How is carbon stored here? Atmosphere Geosphere Hydrosphere How does the water cycle purify water?

5 H.B.6B.2 Analyze and interpret quantitative data to construct an explanation for the effects of greenhouse gases (such as carbon dioxide and methane) on the carbon cycle and global climate. I can... explain the greenhouse effect. analyze and use data to explain how greenhouse gases affect global climate. Explain what the greenhouse effect is, types of gases, and how it affects global climate. Why is the greenhouse effect essential for life? Amount of CO 2 in the atmosphere Greenhouse effect Average Global Temperature Plant cover on Earth Rate of photosynthesis Amount of CO 2 absorbed by plants Amount of CO 2 in the atmosphere higher increases increases Increases increases Increases decreases lower decreases decreases decreases decreases Decreases increases Based on the above chart, describe HOW carbon dioxide in the atmosphere (higher/lower) impact plants. Using the chart as reference, what impact would burning of fossil fuels have on the environment? Explain the analogy below: Greenhouse effect is like a blanket.

6 According to the data to the left, which locations have the highest greenhouse gas emissions? Predict the reasons why. What pattern(s) do you notice on the graphs? Do peaks (top) represent glacial (cold) periods, or do troughs? How do you know? What is the connection between temperature and carbon dioxide?

7 I Can Statement Conversation/Assignment H.B.6D. Conceptual Understanding: Sustaining biodiversity maintains ecosystem functioning and productivity which are essential to supporting and enhancing life on Earth. Humans depend on the living world for the resources and other benefits provided by biodiversity. Human activity can impact biodiversity. H.B.6D.1 Design solutions to reduce the impact of human activity on the biodiversity of an ecosystem. I can... identify why humans are dependent on the Earth for ecological resources. research threats to biodiversity including habitat destruction, invasive species, pollution, human population growth, over- harvesting of resources. Properly functioning ecosystems recycle human wastes, including CO2. A loss of biodiversity has long-term effects and can reduce an ecosystem s stability. Biodiversity or Biological diversity means the variety of organisms at all levels in an ecosystem; it describes both species richness (the total number of different species) and the relative abundance of each species. Threats to biodiversity include: habitat destruction (rainforests, wetlands, habitat fragmentations), invasive species, pollution, human population growth, and over-harvesting of resources. List ways in which humans are dependent on the Earth for ecological resources. What two major impacts do humans have on the environment? Why is the ozone layer important for life on earth? What role do humans play in creating a hole in the ozone layer? Explain the analogy below: Ozone layer is like sunscreen. Describe the population trend worldwide. What is carrying capacity? Describe what will happen once the human population surpasses the carrying capacity? What specific resources will become limited and control human population. What negative effects occur as human population increases/reaches carrying capacity?

8 Over- harvesting occurs when a resource is consumed at an unsustainable rate. This occurs on land in the form of overhunting, excessive logging which results in deforestation, poor soil conservation in agriculture and the illegal wildlife trade. About 25% of world s fish are now overfished to the point where they cannot be harvested sustainably. What is sustainability? Describe the difference between non- renewable and renewable resources. Provide an example of each. Can a renewable resource turn into a non- renewable resource? Explain you answer.

9 I can... define biodiversity, genetic diversity, species diversity, and ecosystem diversity. identify three ways that humans respond to invasive species. use research to design a plan for ecological restoration. explain why human population growth is threat to biodiversity. Draw a line from each term to the correct definition. Biodiversity encompasses the variety of habitats that occur within a region Genetic Diversity the variety of organisms at all levels in an ecosystem Species Diversity Ecosystem Diversity the combination of different genes found within a population of a single species, and the pattern of variation found within different populations of the same species. the variety and abundance of different types of organisms that inhabit an area.
