1 Name: ate: 1. Two different species with the same ecological niche are placed in the same habitat. These two species will most likely. have different food requirements. compete for the same environmental resources. coexist successfully in the same habitat. interbreed and produce hybrid offspring 4. Which is an example of a biotic factor that would limit the size of a deer herd?. populations of predators. severe summer drought. lack of oxygen at high altitudes. heavy winter snowfalls 2. Hawks and owls living in the same area compete for the same type of mouse for food. Which situation would lead to the greatest problem in food supply?. an increase in the owl population. an increase in the mouse population. a decrease in the hawk population 5. Which is an abiotic factor that could affect the survival of organisms in their environment?. algae present in the water. inorganic substances in the substratum. earthworms present in the soil. bacteria of decay in the soil. a decrease in the owl population 6. Which event illustrates the interaction of an abiotic factor with a biotic factor in the environment? 3. Which represents a community?. all the Paramecium candatum in a pond. the abiotic factors in Lake Michigan. all the interacting populations in a forest. the concentration of minerals in soil. The lamprey eel survives by parasitizing trout.. The temperature of water affects its oxygen level.. The low light intensity of the forest affects the growth of pine trees.. gypsy moth caterpillar eats the leaves of an apple tree. page 1

2 7. Which is an example of a changing biotic factor in an ecosystem? 9. In the food web shown, which organisms contain the greatest amount of stored energy?. seasonal changes in temperature. an increase in sunlight during the summer. seasonal migration of birds. and increase in the usual amount of winter snowfall. snakes and hawks. rodents and insects. weeds and shrubs. insects and hawks 8. The diagram shown represents four possible pathways for the transfer of energy stored by green plants. 10. Which sequence of organisms best represents the flow of energy in an ecosystem?. autotrophs herbivores carnivores Through which pathway would the Sun s energy be most directly available to humans?. I. II. III. IV. secondary consumers producers heterotrophs. carnivores deocmposers producers. consumers heterotrophs saprophytes page 2

3 11. Which statement best explains why a food web is a more realistic representation of nutritional patterns than a food chain?. Energy is consumed in metabolic activities and gained at every feeding level.. ecomposers return materials from the top-order predators to inorganic form. 14. Some small fish attach themselves to the body of a shark without harming it and feed upon its left over food. This relationship between the shark and the fish is an example of. commensalism. mutualism. competition. parasitism. Energy always flows through the consumers to the producers.. Practically all species are consumed by or feed on more than one species. 12. The relationship between athlete s foot fungus and humans is known as 15. The diagram shown is of a lake ecosystem. The diagram shows a cross section of a deep lake. The dashed line which separates level from level indicates the depth beyond which light cannot penetrate.. synthesis. mutualism. parasitism. commensalism 13. Some hydras have green algae living symbiotically inside their bodies. The algae produce food for the hydra and receive carbon dioxide and shelter from the animal. What type of relationship exists between the two organisms? Which type of organism that ordinarily inhabits a lake ecosystem would not be found in level because of the lack of light penetration?. decomposers. scavengers. carnivores. producers. parasitism. commensalism. mutualism. saprophytism page 3

4 16. In which population would gene frequencies most likely show the least change as time passes? Pop. OMPRISON OF FOUR NIML POPULTIONS Relative Size of Pop. Type of Mating Frequency of Mutations very small random high large nonrandom moderate small random low large random low... c. 17. The graph shown represents the population growth curves of two different species of aquatic organisms, and. What is a valid prediction based on this graph? 18. The bark of trees around Manchester, England was covered with white lichens before the Industrial Revolution. Light-colored peppered moths that rested on the trees were camouflaged against bird predators, while dark-colored peppered moths were easily preyed upon. fter a few years of industrialization the tree bark darkened from pollution. The table shown represents a change in the number of light- and dark-colored moths within the peppered moth population over a period of 6 years from the beginning of industrialization. End of Year ata Table Number of Light Moths Number of ark Moths The number of dark-colored moths was closest to the number of light-colored moths at the end of which year of the study? Species will not be present in the water during the winter months.. Species will eliminate species from the water after 1 year.. Species will attain maximum population size each autumn due to a decrease in water temperature.. Species will decrease in population size approximately 1 month after a decrease in the population size of species. page 4
