Trophic Level: Level of energy storage Rule of Ten: Max amount of energy transferred is 10% (LOOSE 90%) - Which is why the pyramid is shaped like a triangle… You get less energy as you go up. -Heat of Metabolism given off by all organisms Primary Trophic Level: Producers: Produce glucose (Base of all systems) *SUN IS THE ULTIMATE SOURCE OF ENERGY* -Nutrients are recycled and energy is wasted Autotrophs: Monosaccharides (glucose) & carbohydrates -Chemical Bond: energy (store) -Chlorophyll & Acc. Pigments Secondary Trophic Level Heterotrophs (Consumers): Energy from autotrophs -Primary heterotroph -Secondary heterotroph -Tertiary heterotroph Example: 1. Deer eats plants: Primary consumer (Herbivore) 2. Human eats deer: secondary consumer (Omnivore/Carnivore) 3. An animal that eats the deer: Tertiary Consumer (Carnivore/Omnivore) FOOD WEB: -All the combinations of the food chain. Bioaccumulation: the buildup of substances in an organism. -DDT : A pollution that affects organisms and its fat soluble, which means it can’t be broken down. CYCLES Biogeochemical Cycles: Hydrological Cycle (Water Cycle)/ Carbon Cycle: -How humans activity affects both: Carbon Cycle: Humans are eliminating plants which removes the process of photosynthesis (deforestation ) and we are burning fossil fuels. = causes an increase in CO2 in the air creating a greenhouse effect. Hydrological Cycle: The removal of plants which catch the water and then evaporate off their leaves, when they’re removed there’s no way to carry out the process in the water cycle such as infiltration, evaporation etc. Population Growth: Birth rate vs. Death rate Growth: Birth Rate-Death Rate Exponential Growth: Birth rate is higher than the death rate Biotic Potential: Max ability to reproduce new life Carrying Capacity: Max organism that can be supported Equilibrium: Birth& death rate is the same ENVIORNMENTAL RESISTANCE= Facts that affect the death rate Density Dependent Limits: ABIOTIC FACTORS (COMMUNITY LEVEL) Predation Parasitism Pathogens Competition: -Community and population level: b/c they need the exact same resources *KNOW THE DIFFERENCE BETWEEN PREDATOR VS. PREY, and PATHOGENS VS. PREDADIATION: community level* -Symbiosis: Scoring the relationship and know what the interaction is. (plus, plus=mutualism)
