Matter and Energy in Ecosystems Review

Carbon Cycle of Matter Label the Carbon Cycle using the following words by copying and pasting the answers into the tags:CombustionDeath and wasteDecompositionFeedingNo decompositionPhotosynthesisRespiration by animalsRespiration by plants Respiration by animals Photosynthesis Respiration by plants Combustion Feeding Death and waste No decomposition Decomposition Water Cycle Label the Water Cycle using the following words by copying and pasting the answers into the tags::CondensationEvaporationGroundwaterInfiltration (percolation)PrecipitationRunoffTranspiration Precipitation Condensation Evaporation Transpiration Infiltration Groundwater Runoff Fill in the missing words using the following word bank: fossil fuels, oxygen, coal, cellular respiration, climate change, oil, glucose, ocean, and photosynthesis. Plants use CO2 in the process of photosynthesis to make sugar (glucose and oxygen gas). Animals use oxygen in the process of cellular respirationand make more CO2. The oceanis the main regulator of CO2 in the carbon cycle because CO2 dissolves easily in it. In the past, huge deposits of carbon were stored as dead plants and animals. Today these deposits are burned as fossil fuels, which include coal, oil, and natural gas. More CO2 is released in the atmosphere today than in the past because of the burning of fossil fuels. Another natural source for CO2 is methane. Too much CO2 in the atmosphere may be responsible for climate change. Match the name of the processes with their correct description. Photosynthesis process used by producers to convert solar energy, carbon dioxide, and water into sugars and oxygen cellular respiration process by which heterotrophs convert chemical energy and oxygen into water, carbon dioxide, and ATP. decomposition process by which organisms breakdown into organic compounds combustion process by which carbon dioxide is released from burning fuels Which of the following increases the amount of carbon dioxide in the atmosphere? increased photosynthesis reduction of cellular respiration increased usage of fossil fuels increase in waste elimination by animals Explain why the amount of carbon dioxide has increased dramatically in the last 200 years. The total amount of carbon, water, and nitrogen on Earth increases decreases stays the same What do the arrows in a food chain represent? the order the flow of energy what is getting eaten Label the parts of the food chain above. grass producer hawk apex predator snake secondary consumer mouse primary consumer Give an example of a decomposer that would fit in with this food chain. Use the tools below to make a food chain with a producer, herbivore, and at least one carnivore. Be sure to label each item as: producer, herbivore, carnivore. Fill in the blanks with the following words: photosynthesis, carbon dioxide, cellular respiration, oxygen, glucose, sunlight, water, energy Photosynthesis cellular respiration Energy glucose oxygen carbon dioxide water sunlight Identify the following as either carbon sources or sinks carbon source cellular respiration combustion adds carbon to the atmosphere carbon sink photosynthesis diffusion into ocean removes carbon from the atmosphere What role does the organism play in an ecosystem? What is it important? Why does the amount of energy gathered by plants not fully transfer up the energy pyramid? What is the importance of the nitrogen cycle? Identify which of the following materials contain carbon Contains Carbon all living things graphite diamonds No Carbon water salt glass Identify the three types of fossil fuels The solid fossil fuel that is also a sedimentary rock: coal.The liquid fossil fuel that can be used to make gasoline: oil.The gaseous fossil fuel that can be used to heat your home: natural gas. The amount of energy that is available from one level of the pyramid to the next 90% 10% 50% it varies Fill in the blanks with the correct word. Remember to scroll down in word bank to see all available words. In 1995, wolves were added back to Yellowstone National Park. Wolves are the apex predator in this food web. When they were added to the park the number of deer decreased. This allowed more trees to grow which then led to an increase in birds, bears, and beavers. The wolves also killed coyotes. Their death led to an increase in rabbits which then help increase the numbers of hawks. Lastly, the wolves changed the behavior of the rivers. They meandered less and were much more clear due to less erosion.Overall the introduction of wolves increased the biodiversity of the park. Label the following carbon reservoirs. (atmosphere, ocean, living organisms, fossil fuels) atmosphere ocean fossil fuels living organisms Give three ways the carbon cycle can become unbalanced. Then explain how we can reduce those effects. Give one way the nitrogen cycle can become unbalanced. Fill in the blanks for the combustion equation fuel + oxygen -> water + carbon dioxide + fire Fill in the equation Fill in the equation. Fill in the blanks. Energy flows through an ecosystem while matter recycles. List several ways you can personally reduce your carbon footprint. Explain how these would help reduce your footprint. Use appropriate vocabulary in your explanation.
