(careful! It didn’t ask how much is passed to the next level) • A diagram showing the complex feeding interactions in a community • What is a food web? • Which trophic level would have the largest biomass in an ecosystem? • What is the first trophic level (autotrophs)? • An organism that eats both animal and plant matter • What is an omnivore? • The two different processes that producers use to make carbohydrates. • What are photosynthesis and chemosynthesis? (Photosynthesis is by far the most common) • Assemblages of populations that live together in a defined area • What is a community? • A community plus all the abiotic factors around it • What is an ecosystem? • A group of similar ecosystems with similar climate and dominant communities. • What is a Biome? • The combined portions of the planet in which all life exists • What is the Biosphere? • All the organisms of a particular species that live in a defined area • What is a population? • The changing seasons we experience are a result of this • What is the tilt of earth’s axis? –Causes changes in the length of days and angle of heating • A particular chemical substance needed by living things that is in short supply in an ecosystem • What is a limiting nutrient? • The average weather conditions an area has year-after-year. • What is climate? • This is the condition in which gases in a planet’s atmosphere, such as CO2, retain heat • What is the greenhouse effect? • This is a process in which nitrogen gas in the atmosphere is converted into a form that living things can use. • What is Nitrogen fixation? • This says that two species cannot occupy the same niche in the same habitat at the same time • What is the competitive exclusion principle? • The role or job that an organism fulfills within its ecosystem • What is a niche? • The area that an organism inhabits is called this. • What is a habitat? • Name for a group of organism so similar to each other that they can breed and produce fertile offspring • What is a species? • This is a word for the evaporation of water from the leaves of plants. • What is transpiration? • Two factors that effect enzyme activity. • What is pH and temperature.
