Questions and CORRECT Answers
what are characteristics shared by all living things? made of cells, obtain and use energy, grow and develop, reproduce,
respond/adapt to their environment
what are the steps to the scientific method? observe, background information, hypothesize, experiment, analyze, draw
conclusions
what is an independent variable? changed by the scientist
what is a dependent variable affected by the change that is done by the scientist
why is it necessary to use controls when testing a to have a comparison for your results
hypothesis?
put this in order from small to large: ecosystem, organism, population, community, ecosystem, biome
organism, biome, community, population
example of an abiotic factor (sun, water, rocks, soil)
example of a biotic factor (grass, bugs)
what is a niche? the way in which an organism fits into an ecological community or ecosystem
what percent of energy is lost through each tropic level 90%; 10% is left
of a food pyramid?
what are the five biogeochemical cycles? water cycle, carbon cycle, nitrogen cycle, phosphorus cycle, oxygen cycle
what is primary succession? primary succession is one of two types of biological and ecological succession of
plant life, occurring in an environment in which new substrate devoid of
vegetation and other organisms usually lacking soil, such as a lava flow or area
left from retreated glacier, is deposited.
what is secondary succession? secondary succession is the series of community changes which take place on a
previously colonized, but disturbed or damaged habitat.
what is the role of enzymes? to act as a catalyst in a reaction within an organism.
what are the four categories of major macromolecules? carbohydrates, lipids, proteins, and nucleic acids
whats the monomer, polymer, and examples of monomer: monosaccharide (ex: glucose, deoxyribose, fructose)
carbohydrates? polymer: polysaccharide (ex: starch, glycogen, cellulose)
DISACCHARIDE (2): sucrose, lactose, maltose
carbohydrates=ose
