Flashcards › Photosynthesis, Cellular Respiration and Nutrient Cycles

non-living abiotic energy currency of cells ATP self-feeder, an organism that produces its own food autotroph living biotic a measure of the amount of energy in food calorie/kilocalorie organisms that consume only animals carnivores process that all organisms use to convert sugar into ATP cellular respiration cell organelle that is the site of photosynthesis chloroplast many different populations of different species that all live in the same area community process where water vapor is converted to liquid water condensation organisms that break down dead or decaying organic matter decomposers science that studies the relationships between organisms and their environments ecology contains the living and non-living parts of a community ecosystem the ability to do work energy evaporation from plants and bodies of water evapotranspiration diagram showing transfer of energy through trophic levels food chain plant-eating organisms, primary consumers herbivore other-feeder, an organism that consumes other organisms heterotroph cell organelle that is the site of cellular respiration, the powerhouse of the cell mitochondrion process that converts nitrogen gas (N2) to compounds that plants can use nitrogen fixation organisms that consume both animals and plants omnivore process that plants use to convert light, CO2 and water into sugar photosynthesis a group of individuals of the SAME species living in a particular area population rain and snow are examples precipitation photosynthetic autotroph (for example plants) producer organism that consumes primary consumers secondary consumer organism that consumes secondary consumers tertiary consumer evaporation from plants transpiration photosysthesis, cellular respiration and nutrient cycles
