Question #1: The members of an animal community are usually similar in; 1) size 2) structure 3) food requirements 4) environmental requirements

Question #2: Which is a biotic factor that affects the size of a population in a specific ecosystem? 1) the average temperature of the ecosystem 2) the number and kinds of soil minerals in the ecosystem 3) the number and kinds of predators in the ecosystem 4) the concentration of oxygen in an ecosystem

Question #3: An overpopulation of deer in a certain area will most likely lead to: 1) a decrease in the number of predators of the deer 2) an increase in the number of autotrophs available for food 3) a decrease in the incidence of disease 4) an increase in competition between the deer

Question #4: Producer organisms function to: 1) store more energy than they use 2) use more energy than they store 3) store energy but not use it 4) neither store nor use energy

Question #5: Which term includes all of the interactions that occur between the organisms and the physical factors in a pond environment? 1) population 2) ecosystem 3) abiotic 4) competition

Question #6: The amount of salt in the air and water of coastal areas determines which species can exist there. In these areas, salt functions as a 1) source of energy 2) biotic factor 3) food source 4) limiting factor

Question #7: In the biosphere, what are some of the major abiotic factors that determine the distribution and types of plant communities? 1) temperature, sunlight, and rainfall 2) humidity, location, and humans 3) soil type, soil bacteria, and soil water 4) insects, carbon dioxide, and nitrogen in the air

Question #8: An earthworm lives and reproduces in the soil. Through its feeding, excretion, and tunneling activities, the worm adds nutrients and allows air to enter the soil. Together, these statements describe the earthworm's 1) habitat 2) nutrition 3) niche 4) environment

Question #9: Predict what would happen to a community if the number of carnivores present suddenly doubled.
