How does energy flow through an ecosystem. Your answer should include:
Define the terms: ecology, ecosystem, community, population, species, habitat, and environment.
Describe the components of an ecosystem, categorizing them as biotic or abiotic factors.
Define the term ecological niche and identify the factors that are used to describe the niche.
State the two laws of thermodynamics.
In practical terms, explain what the energy laws mean with respect to energy conversions in ecosystems.
Describe the efficiency of energy transfer between tropic levels, and explain the small biomass and low numbers of organisms at higher trophic levels. Explain what happens to the energy that is not transferred.
Construct a food chain and food web for a named community. Show how the organisms are interconnected through their feeding relationships and assign them to trophic levels.
Describe energy flow quantitatively using an energy flow diagram. Include reference to trophic levels, direction of energy flow, processes involved in energy transfer, energy sources, and energy sinks.
Describe food chains quantitatively using ecological pyramids. Explain how these may be based on numbers, biomass, or energy at each trophic level.
the forms in which energy occurs
How are materials cycled between the processes of photosynthesis and cellular respiration? Your answer should include:
Explain the need for energy in living things and the universal role of ATP in metabolism.
Describe the synthesis of ATP from ADP and inorganic phosphate (P) and explain how it stores and releases energy. How ATP is made
relate the importance of the electromagnetic spectrum to photosynthesis.
Explain the process of chromatography in relation to plant pigments
Describe the reactions of photosynthesis, light dependent reactions and light independent reactions, using a diagram.
Explain the role of the accumulation of H+ and ATP synthase to the generation of ATP.
Draw and label the structure of a mitochondrion including the cristae and matrix.
Understand the situations in which fermentation may occur and identify the H+ acceptor in the formation of lactic acid in muscle or alcohol in yeast.
Compare and explain the differences in the yields of ATP from aerobic respiration and fermentation
Appreciate that both photosynthesis and cellular respiration involve the molecular ATP and hydrogen carriers, and identify both of these processes.
