What is biotic and abiotic? Term for the assortment of living organisms. What is biodiversity? A scientist studies a system with zebras, grass, lions and hyenas. If the lions are removed, the system collapses. The lions are an example of ______ _____. What is a keystone species? If you have 3 species of finch living in an area, you have a _______. What is a community? Name the 5 levels of organization from small to large. What is organism, population, community, ecosystem and biome? The definition of chemosynthesis. What is an organism that makes its food from chemicals? An organism that makes its own food. What is an autotroph? An organism that eats “different” types of food. What is a heterotroph? These 2 critical chemical reactions are the opposite of each other. What is photosynthesis and respiration? Ecosystems are dependent on producers for this reason. What is producers support the entire ecosystem? These show a linear trophic pattern. What are food chains? Definition of a specialist. What is an organism that relies on one type of food (like one species of plant)? Name 3 types of consumers. GO! What are herbivores, carnivores,omnivores, detritivores and/or decomposers? A big fish that ate a medium sized fish that ate a smaller fish that ate phytoplankton is called this (HINT: the term for the big fish). What is a tertiary consumer? The difference between a decomposer and a detritivore. What is the decomposer breaks the decaying matter down completely and returns it to the ecosystem? What is the detritivore breaks down the plant or animal after it dies? Name for all the cycles. What is biogeochemical cycle? This cycle is dependent on soil bacteria. What is the Nitrogen Cycle? This makes up most of the air in our atmosphere and when its in this form its not available to ecosystems. What is Nitrogen and N2? These 2 cycles are both intimately involved with respiration. What are the Carbon & Oxygen cycles? The Phosphorus cycle is dependent upon rocks in these 2 ways. What is weathering of rock makes P available to the ecosystem and geologic uplifting push more rock to the surface ? A pyramid that depicts how many plants and animals are present at each trophic level. What is a numbers pyramid? The definition of a biomass pyramid. What is a pyramid based on the amount of matter at each trophic level? This is why pyramids are used to depict the energy available in an ecosystem. What is as you move up the trophic levels, there is less energy available and a pyramid shows that? Not all energy that is consumed is transferred to the next trophic level It is transformed into ______. What is heat? If the producer’s trophic level has 1,000,000 kcal available, about this much energy will be transferred to the next level. About 10% of the energy gets transferred, so what is about 100,00 kcal?
