1. 2. Thursday, February 14, 2013 What elements are found in carbohydrates? What elements are found in proteins? 1. 2. 3. Categorize ecology terms for describing the different stages of an ecosystem. Describe the difference between abiotic and biotic factors. List real world examples of autotrophs and heterotrophs. Ecology = study of interactions among organisms & their surroundings (environment) = group of organisms that can breed & produce fertile offspring Example: Cave Shrimp Non-example: Mules Why isn’t a mule an example of a species? = group of organisms that belong to the same species & live in the same area. Example: group of cave shrimp in a single cave = group of different populations that live together in a defined area Example: cave shrimp, isopods, amphipods, & bacteria (in an underwater cave) = Collection of all organisms that live in a particular place, together w/ nonliving or physical environment. Example: Cave System in Bermuda = group of ecosystems that have the same climate & similar dominant communities Example: desert, tundra, rain forest. = part of the earth & its atmosphere in which living organisms exist or that is capable of supporting life Made up of: land water air (atmosphere) Draw a series of 5 circles: smallest in the center & largest on the outside. Put the following terms in the circles to show how they fit together. Terms: Biome Biosphere Community Population Ecosystem = study of life Latin Root: Bio = Life = any living component that affects another organism Examples: Competitors Predators Prey Disease (Bacteria) = physical or nonliving things that shape an ecosystem Examples: Soil Weather Light Water = ecological role & space an organism fills in its environment/ecosystem Example: Bee acts as a pollinator in its ecosystem = Organism makes own food for energy Latin Roots Auto = self Troph = nutrition/energy Examples: plants, algae, some bacteria 2 types: 1) Chemoautotroph – make own food using chemicals. 2) Photoautotroph – make own food using light. AKA PRODUCERS = Organisms rely on other organism for food (eat other organisms) Latin Roots Hetero – different Troph – nutrition/energy AKA CONSUMERS Example: mammals, birds, fish = Organism eats only meat Example: Lion = organism eats only plants Example: zebra Organisms eat both plants & animals Example: Baboons Organisms eat dead or decaying matter AKA Scavenger Example: vulture Organisms that break down dead or decaying matter externally, then take it in. Example: fungus Provide a different example of each of the following on the next blank page: Herbivore Carnivore Omnivore Detritivore Decomposer Autotroph Heterotroph Use a different color for each! Friday, February 15, 2013 What type of biomolecule is represented by the following image? 1) 2) List the important levels in a food chain Create a food web for a real world organism. carnivore omnivore herbivore Heterotroph/3rd (tertiary)level consumer Heterotroph/2nd (secondary) level consumer Heterotroph/1st (primary) level consumer Autotroph/producer = Energy levels in a food chain or food web Each level receive ONLY 10% of the previous trophic level’s energy INEFFICIENT!!! How much energy will the rabbit get from his meal? How much energy will the lion get from his meal? Why doesn’t the rabbit get 1000Kg of energy from the grass? 0.1% carnivore 1% omnivore Trophic levels 10% herbivore 100% Heterotroph/3rd (tertiary) level consumer Heterotroph/2nd (secondary) level consumer Heterotroph/1st (primary) level consumer Autotroph/producer 1) 2) 3) Select an organism you want to learn more about Determine what type of environment it lives in Determine the predators and prey items in that environment Draw the food web (Use names or pictures.) List the producers. List the primary consumers. List the secondary consumers. Label each animal as herbivore, carnivore or omnivore. User name: 1st 5 letters Last Name (lowercase), 1st 3 letters 1st Name (lower case), 000 Example: malonbri000 Password: Student ID # Lunch # Monday, February 18, 2013 1.What is the function of an enzyme? 2. What 3 letters do most enzymes end in? 1. 2. 3. Compare and contrast the different types of symbiotic relationships. Give real world examples of the 5 different types of symbiotic relationships. Determine the carrying capacity from a graph. Symbiosis = any relationship btw 2 organisms that live closely together 5 types…… = interaction where one organism hunts & kills another Predator – hunter Prey – food Example: lion hunting zebra = relationship where both organisms benefit Example: bees & flowers = relationship where 1 organism benefits & other is neither harmed or benefited Example: whales & barnacles = relationship where 1 organism benefits & other is harmed Example: tick & dog mosquito & human = relationship where 1 organism competes with another for food, shelter, mate, etc. Give an example from one of our ecosystems for each of the following terms. Competition Parasitism Mutualism Commensalism Predation Use a different color for each! = amount of life an ecosystem can support w/ its resources Balance between life (reproduction) & death Birth rate vs death rate What is the carrying capacity in this graph? Why is the purple line going up and down? 1) 2) 3) 4) Add title to Table of Contents Turn to next blank page & add title Write definition of carrying capacity (1st sentence on the front of the paper) Answer Questions on the back of the paper in COMPLETE SENTENCES Question #1 – 2 sentences Question #2 – 3 sentences Tuesday, February 19, 2013 Looking at the graph below, adding an enzyme to the reaction lowers the what? 1. 2. Interpret a graph to determine the carrying capacity for a population. Evaluate the resources available for a population to predict the future trends in a carrying capacity graph. Wednesday, February 20, 2013 What type of diagram is represented by the following image? 1. 2. 3. List the major components of the carbon cycle. Predict the real world effect of an unbalanced carbon cycle. List the major components of the nitrogen cycle. Moves between the ocean, atmosphere (atm), & land Carbon (C) is the key ingredient for ALL living tissue In the atmosphere (atm), C is present as Carbon Dioxide gas (CO2) CO2 is released into atm by: 1. Volcanoes 2. Respiration (when you exhale) 3. Human activities: burning fossil fuels & vegetation 4. Decomposition of organic matter Plants take in CO2 during photosynthesis Use the CO2 to build carbohydrates Carbohydrates are passed along in the food webs to animals & other consumers Decomposition Animals die C is released & passed back into the atm Explain what is happening in box #1. #1 #2 #3 Explain what is happening in box #2. Burning fossil fuels releases C into the atmosphere. We breath out C. Explain what is happening in box #3. Plants use CO2 for photosynthesis. All organisms require Nitrogen (N) to make amino acids Make up proteins N2 gas makes up 78% of the atm Nitrogen Fixation = Bacteria living in the soil fix it so we can use it Convert N2 gas into ammonium NH4 N2 → 2NH4 Consumers eat the producers & reuse the N to make proteins When organisms die, decomposers return nitrogen to the soil as ammonia = bacteria converts the nitrates to N2 gas & returns to the atm NO3 N2 Avid Thinking Strategy • Map News!

New Vocabulary Name of Source Date Topic: One of the cycles we discussed today Branch of Science (Biology) Clues Evidence Science Fact Conclusion Thursday, February 21, 2013 Draw an energy hill diagram on the following graph. Include a curve for w/ & w/o an enzyme. 1. 2. Compare and contrast primary and secondary succession. List real world examples of succession. = series of natural changes that take place in environment 1. - Primary Succession = takes place over land where there are NO LIVING organisms. Very slow process! Example: Lava from a volcano destroys everything in its path. ( no soil ) 2. Secondary Succession = changes which take place AFTER an existing community is severely disrupted. - occurs in an area that previously contained life on land that still contains soil. - Example: hurricane, forest fire, tornado Pioneer Species = 1st species to occupy an area undergoing primary succession Example= Lichen Climax community = stable, mature community that undergoes little or no change in species. ***It can last for hundreds of years*** Friday, February 22, 2013 Define carrying capacity in your own words.
