Flow of Energy/Matter through the Environment

Photosynthesis (Starts the flow of energy)

Point Form, REACTANTS Carbon Dioxide and Water under CONDITIONS of Light Energy and chlorophyll results in PRODUCTS of glucose and oxygen

Equation, Word, Carbon dioxide + water-(Sunlight and chlorophyl)-> glucose +oxygen, Chemical, 6CO2 + 12H2O -(Sunlight and chlorophyl)-> C6H12O6 + 6O2 + 6H2O, Reactants (6CO2 + 12H2O), conditions (Sunlight and chlorophyl) and products (C6H12O6 + 6O2 + 6H2O), Factors, Dependent Variables, E.g. Starch, Independent Variables, E.g. Sunlight, Metabolic Reaction, Anabolism, "To make from simpler units", Catabolism, "To break up complex units"

Paragraph Form, a process whereby light energy is trapped by chlorophyll and converted into chemical energy which is then utilized to manufacture carbohydrates/glucose from raw materials such as carbon dioxide and water. Oxygen is released as a by-product

Performing Starch test, Place leaf in boiling water to kill the cell and tear open the cell membranes so the iodine stain can easily enter the cells. Place leaf in boiling alcohol to remove the green chlorophyll so the final results can be clearly seen Dip leaf into warm water to remove the alcohol so the iodine stain can penetrate the leaf. Cover leaf with iodine solution to test for the presence of starch. Those parts of the leaf that stain blue-black contain starch. Those parts that are yellow-brown (the colour of the iodine stain) do not have starch.


Food Chains, Is a series of organisms through which energy is trasnferred in material form, should have only 4 trophic levels, 1st Trophic level, producer organisms(plants), 2nd Trophic level, primary consumers(herbivores), 3rd Trophic level, secondary consumers(carnivores), primary and secondary consumers (omnivores), 4th Trophic level, tertiary consumers (carnivores), possible 5th Trophic level, quaternary consumers, Energy Loss, A lot of energy is lost through the trophic levels, About 90% is lost when transferred from one level to next, Greatest loss - during transfer from producer to primary consumer, Due to Life Processess, Respiration, external, Involves no chemical reactions-Purely physical, cellular, aerobic, Oxygen+Glucose -> CO2 +H2O +energy, anaerobic, Glucose ->CO2+H2O+Energy+lactic acid, Egestion (defecation), Metabolic waste, Undigested Material, Excretion, Decomposition, Ecological Pyramids, graphical representation, feeding relationships of organisms, biomass or productivity at each trophic level in a given ecosystem

Food web, An interconnection of several food chains at many points

Trophic levels


Process, input-->output


Living organisms need it, perform various vital functions, to live

Plants, Energy comes from the sun, Autotrophic nutrition, process where an organism builds up the organic molecules that it requires from simple inorganic materials

Animals, Heterotrophic nutrition, process whereby an organsism uses organic compounds for most or all of its actions

Modes Of Nutrition (Trophic Levels)

Autotrophs, Definition, Producers, E.g. Plants, a PROCESS, where an organism builds up the organic molecules that it requires from simple inorganic molecules such as carbon dioxide and water, Chemoautotrophs, An organism (typically a bacterium or a protozoan) that obtains energy through chemical process, E.g. Hydrothermal Vents, Photoautotrophs, An organism, typically a plant, obtaining energy from sunlight as its source of energy to convert inorganic materials into organic materials., E.g. Plants

Hetrotrophs, Definition, Consumers, E.g. Animals, a PROCESS, whereby an organism uses organic compounds for most or all of its carbon requirements, Holotroph, Organisms that are capable of consuming other organisms in whole., E.g. Humans, Saprotrophs, An organism(most often associated to fungi) that is involved in the processing of dead or decayed organic matter., E.g. Fungi







How organism A lives with organism B

Symbiosis, Mutalism, Both benefit, E.g. Nitrogen bacteria and plants., Commensalism, One benefits, the other has no harm nor benefit, E.g. Clownfish and Anemone-The anemone protects the clownfish from fish-eaters, while the anemone stays relatively neutral., Parasitism, One benefits from the other, E.g. Moth and mites-the moth infested by mites-they crawl up its tongue while it's drinking nectar. The moth's ear is warm and moist-perfect breeding grounds for the mite Because they block the ear, the moth can't hear and they get eaten by bats.


Abiotic, Non-living, E.g. The enviroment

Biotic, Living, E.g. animals

Drawing, Draw within the box, Show differences(e.g. shape, color, margin, venation type [variables]), Use sharp, easy to erase pencils, Draw only what is relevant, NO descriptions, Every drawing must have a title

Dichotomous key, Have what you listed on your drawing, Have as many levels as features, Try not to draw "V"

Open-Ended, Write within the lines
