1) What is an abiotic factor that affects ecosystems? a) Temperature b) Predation 2) How do abiotic factors like temperature and water availability affect ecosystems? a) They influence the survival and distribution of organisms in an ecosystem. b) They only affect the growth of plants but not animals. 3) Which of the following is an example of a biotic factor in an ecosystem? a) Soil pH level b) A predator hunting prey 4) How does predation impact the population of prey in an ecosystem? a) It reduces the population of prey species. b) It increases the population of prey species. 5) What is the effect of competition on species within an ecosystem? a) It encourages the growth of populations. b) It can limit resources and reduce population sizes. 6) What is an example of a mutualistic relationship? a) A lion hunting a zebra b) A bee pollinating a flower 7) What is an ecological niche? a) The physical location where an organism lives. b) The role and position an organism has within its environment. 8) How does disease affect populations in ecosystems? a) It has no effect on populations. b) It can decrease the population size and impact species survival. 9) What might happen to a species if it faces intense competition in an ecosystem? a) The species' population might decrease or even go extinct. b) The species' population will grow exponentially. 10) Which of the following is a common method used to measure populations of organisms? a) Counting individual organisms by eye b) Quadrat sampling 11) What is the effect of symbiotic relationships on populations? a) Symbiotic relationships can either benefit, harm, or have no effect on the populations involved. b) Symbiotic relationships always harm one of the populations. 12) Which of the following is not considered an abiotic factor? a) Animals b) Water 13) What is a possible long-term consequence of heavy predation on prey populations? a) The prey population may decrease, leading to less food for predators. b) The predator population will increase indefinitely. 14) What happens if two species have the same ecological niche? a) They will both thrive without any issues. b) They may compete for resources, and one species could be outcompeted. 15) What is the main goal of using sampling techniques in measuring populations? a) To track the daily movements of individual organisms. b) To estimate the number of individuals in a population without counting every individual.
