This colorful and engaging PowerPoint presentation, "Ecosystems: Energy Flow and the Recycling of Matter", will provide your students with interactive lessons on the ecological principles concerning the flow of energy through the ecosystems well as the biogeochemical cycles (carbon cycle, water cycle, nitrogen cycle) responsible for the recycling of matter.
What is Included?
• 83-slide PowerPoint presentation
• Lecture notes for the teacher (12 pages)
• Note-taking outline for the students (16 pages).
Ecology is one of the "must-teach" topics for any biology or life science class. What would a good biology class be without a strong unit (or units!) in Ecology? This colorful and visually appealing PowerPoint is just what you need to spice up your ecology lessons. Our students are the decision makers of tomorrow. It is imperative that we give them the ecological knowledge (global warming, greenhouse effect, habitat destruction) they need so that they can make informed decisions about our future.
This PowerPoint is on "Ecosystems and the Biosphere: Energy Flow and the Recycling of Matter". It consists of 83 slides that are colorful, informative and visually stimulating. Pictures and diagrams are included that will greatly enhance your instruction to your students. Graphics, diagrams, clip art, and photographs were chosen to capture the attention of the student as the lesson is being taught.
Topics covered in this lesson are:
• Energy Flow Through the Ecosystem: Sunlight as a source of energy, importance of photosynthesis, conversion of energy into glucose and other organic compounds.
• Autotrophs, producers, examples of autotrophs, chemoautotrophs and chemosynthesis.
• Heterotrophs, consumers, examples of heterotrophs, herbivores, carnivores, omnivores, detritivores, decomposers, the essential nature of decomposition.
• Feeding Relationships: One way flow of energy through the ecosystem, food chains, examples of food chains, food webs, trophic levels, primary producers, primary consumers, secondary consumers, tertiary consumers.
• Productivity of the Ecosystem: Two ways to measure productivity, gross primary productivity, the role of glucose in productivity, biomass, net primary productivity, factors that determine productivity in both terrestrial and aquatic ecosystems.
• Energy transfer between trophic levels, ecological pyramids, percentage of energy that moves up to the next trophic level, reasons why the transfer of energy is so low.
• Given a hypothetical food chain, the student will identify the autotroph, the primary consumer, secondary consumer, and tertiary consumer as well as calculate the amount of energy passed to each trophic level.
• Ecosystem recycling: the recycling of matter, the essential need to recycle carbon, nitrogen, water, and phosphorus, biogeochemical cycles.
• Water Cycle: Location of water, evaporation, precipitation, transpiration, condensation, steps to water cycle, students will complete a diagram of the water cycle.
• The Carbon Cycle: The importance of carbon to organic compounds, the role of photosynthesis and cellular respiration in the carbon cycle, the role of erosion and volcanic activity in the carbon cycle, decomposition, burning of fossil fuels, steps to the carbon cycle, the student will label a diagram of the carbon cycle, the human impact on the carbon cycle.
• The Nitrogen Cycle: The importance of nitrogen in building proteins and nucleic acids, nitrogen fixation, ammonification, nitrification, denitrification, assimilation, the role of various bacteria in the nitrogen cycle, students will label a diagram of the nitrogen cycle.
• The Phosphorus Cycle: The importance of phosphorus to ATP and nucleotides, the movement of phosphorus through the ecosystem.
• Limiting nutrients
This PowerPoint was written with a typical biology I class in mind. It can easily be edited to meet your needs.
This teaching resource includes a complete set of lecture notes for the teacher, and an outline of the notes for the students. Students will use the outline as the PowerPoint is being presented and will fill in the notes as the lesson is being taught. I always include both the Word document and a pdf of the notes.
