Ecology Study Guide SB4. Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems. a. Investigate the relationships among organisms, populations, communities, ecosystems, and biomes. Complete the graphic organizer b. Explain the flow of matter and energy through ecosystems by -Arranging components of a food chain according to energy flow. Go to the following website and practice arranging organisms in a food chain. http://www.ecokids.ca/PUB/eco_info/topics/frogs/chain_reaction/index.cfm -Comparing the quantity of energy in the steps of an energy pyramid. Analyze the picture below and explain how the quantity of energy changes with each step. -Explaining the need for cycling of major nutrients (C, O, H, N, P). Complete the table. Cycle Carbon Cycle Nitrogen cycle Used for: Located Carbon atoms continually move through living organisms, the oceans, the atmosphere, and the Earth’s interior and crust. Nitrogencontaining substances such as ammonia (NH3), nitrate ions (NO3), Processes that move the elements through their cycle: photosynthesis, respiration, and decomposition take up & release CO2 and O2 • • Bacteria convert nitrogen gas usable forms for producers through nitrogen fixation. Consumers eat the producers and reuse and nitrite ions (NO2) are found in soil, in the wastes produced by many organisms, and in dead and decaying organic matter. • • • Phosphorus cycle Oxygen Phosphorus in the form of inorganic phosphate remains mostly on land, in the form of phosphate rock and soil minerals, and in the ocean, as dissolved phosphate and phosphate sediments. • Atmosphere, organisms • • • • • nitrogen to make their own nitrogen-containing compounds. Decomposers release nitrogen from waste and dead organisms. Other soil bacteria obtain energy by converting nitrates into nitrogen gas through denitrification. Humans add nitrogen to the biosphere through the manufacture and use of fertilizers. As rocks and sediments wear down, phosphate is released. Some phosphate stays on land and cycles between organisms and soil. Plants absorb phosphorus that is dissolved in the soil water Organic phosphate moves through the food web, from producers to consumers, and to the rest of the ecosystem. Other phosphate washes into rivers and streams, where it dissolves. This phosphate eventually makes its way to the ocean, where marine organisms process and incorporate it into biological compounds. Oxygen participates in parts of the carbon, nitrogen, and phosphorus cycles by combining with these elements and cycling • with them through parts of their journeys. Oxygen gas in the atmosphere is released by one of the most important of all biological activities: photosynthesis. c. Relate environmental conditions to successional changes in ecosystems. Define Ecological succession Primary succession. Pioneer Species Secondary Succession d. Assess and explain human activities that influence and modify the environment such as global warming, population growth, pesticide use, and water and power consumption. Humans impact Earth through agriculture, development, and industrial growth. Define Examples Renewable Resources Nonrenewable Resources e. Relate plant adaptations, including tropisms, to the ability to survive stressful environmental conditions. f. Relate animal adaptations, including behaviors, to the ability to survive stressful environmental conditions. To survive organism have adaptations. Please complete the following table with adaptations that organisms would have in the describe condition. Adaptations Environmental Condition Dry Season Shaded by taller plants. Predators Cold Plants Animals
