DIAGNOSTIC TEST ECOLOGY TERMS Multiple Choice Questions 1. The study of the interrelationships of living organisms and their environment is: A. ecology B. ecosystem C. environment 2. All the living and non-living conditions that act on an organism and affect its chances of survival is the: A. ecology B. living factor C. environment 3. Another term meaning ‘living’ is: A. biology B. biotic C. ecological 4. Another term for ‘non-living’ is: A. abiotic B. biotic C. dead 5. All the organisms in a particular area at a given time is the: A. community B. species C. habitat 6. The number of a particular species in an area at a given time is the: A. community B. species C. population 7. The area in which an organism lives is its: A. range B. habitat C. nesting site 8. Another term for ‘on land’ is: A. aquatic B. terrestrial C. marine 9. The role or position a species occupies in a community is its: A. niche B. habitat C. micro-habitat 10. A natural unit of living and nonliving parts that interact to produce a stable system in which the exchange of materials between living and non-living parts follows a circular path is called: A. a cycle B. an ecosystem C. an environment True-False Questions 11. Photosynthesis is the process used by plants to take in oxygen and sugar and produce energy. 12. All living and non-living things on earth are interrelated. 13. Respiration is the opposite of photosynthesis. 14. Abiotic factors include amount of water and oxygen, temperature, amount of sunlight and water pressure. 15. Biotic factors include other animals but not bacteria. Short Answer Questions 16. What abiotic factors would affect marine fish? 17. What biotic factors would affect marine fish? 18. How are plants affected by sunlight? 19. What is the difference between the terms ‘aquatic’, ‘freshwater’ and ‘marine’? 20. List the factors that would affect the population of a species. DIAGNOSTIC TEST ECOLOGY TERMS ANSWERS 1.A 2.C 3.B 4.A 5.A 6.C 7.B 8.B 9.A 10.B 11.F 12.T 13.F 14.T 15.F 16. movement depth pressure temperature salinity and viscosity of the seawater, amount of dissolved oxygen and carbon dioxide, amount of light penetration 17. amount of food, predators, parasites 18. The duration and intensity of sunlight affects the process of photosynthesis in all plants. Extreme heat would also affect the transpiration or water loss of plants. The number of hours of darkness in each 24 hour period affects the flowering time of many flowering plants. 19. Aquatic = in water, Freshwater = freshwater (low dissolved salt), Marine = seawater (high dissolved salt) 20. Available resources (food, water, shelter), activities of other organisms (predators, diseasecausing parasites), the organism’s own characteristics (gestation period, number of young), time of day or year (nocturnal or diurnal, migratory), weather (amount of rain, cyclone)
