This power point explains the flow of energy through an environment. It discusses how sunlight is converted during photosynthesis and how organisms then use cellular respiration. Trophic levels, energy pyramid, food chains and food webs are all covered.
Students will be able to identify which trophic level an organisms belongs in and understand how the cellular process of photosynthesis and cellular respiration allow energy to flow through an environment.
GREAT FOR ANY STATE!!!
Texas Biology TEKS
(10) Science concepts. The student knows that biological systems are composed of multiple levels. The student is expected to:
(A) describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals;
(C) analyze the levels of organization in biological systems and relate the levels to each other and to the whole system.
(11) Science concepts. The student knows that biological systems work to achieve and maintain balance. The student is expected to:
(C) summarize the role of microorganisms in both maintaining and disrupting the health of both organisms and ecosystems; and
(12) Science concepts. The student knows that interdependence and interactions occur within an environmental system. The student is expected to:
(C) analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs, and ecological pyramids;
(E) describe the flow of matter through the carbon and nitrogen cycles and explain the consequences of disrupting these cycles; and
NEXT GENERATION SCIENCE STANDARDS
HS-LS1-5. Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy. [Clarification Statement: Emphasis is on illustrating inputs and outputs of matter and the transfer and transformation of energy in photosynthesis by plants and other photosynthesizing organisms. Examples of models could include diagrams, chemical equations, and conceptual models.]
HS-LS1-6. Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules. [Clarification Statement: Emphasis is on using evidence from models and simulations to support explanations.]del to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy. [Clarification Statement: Emphasis is on the conceptual understanding of the inputs and outputs of the process of cellular respiration.]
HS-LS2-3. Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions. [Clarification Statement: Emphasis is on conceptual understanding of the role of aerobic and anaerobic respiration in different environments.]
HS-LS2-4. Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem. [Clarification Statement: Emphasis is on using a mathematical model of stored energy in biomass to describe the transfer of energy from one trophic level to another and that matter and energy are conserved as matter cycles and energy flows through ecosystems. Emphasis is on atoms and molecules such as carbon, oxygen, hydrogen and nitrogen being conserved as they move through an ecosystem.]
HS-LS2-5. Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
