A species of plant or animal that is facing imminent extinction or extirpation is said to beExtinctExtirpatedEndangeredThreatened2. A diagram that shows how energy moves through the ecosystem (producer, consumers, decomposer) Food WebEcological SuccessionFood ChainEnergy Pyramid3. Consider this food chain: algae --> water fleas --> minnows --> trout --> bear The minnows in this food chain are:Tertiary carnivores.Secondary carnivores.Top carnivores.Primary carnivores.4. The process by which one community is replaced by another; bedrock - lichens - mosses- grasses - trees and shrubs - forest Ecological NicheEcological successionEnergy PyramidHabitats5. A food web is more realistic than a food chain for showing the feeding relationships in ecosystems because:Food chains use only a small sampling of organisms.It compares the number of consumers to the number of micro-organisms in an ecosystem.Producers are usually eaten by many different consumers and most consumers are eaten by more than one predator.A food web explains why there are more producers than consumers.6. Space where an organism lives and the role an organism plays within its ecosystem is referred to as a:NicheSamplingCommunityPopulation7. When populations share their environment and interact with populations of other species, it is called a: CommunityEcoprovinceBiomeSpecies8. Heterotrophs obtain energy from all of the following except: AutotrophsSolar radiation.HerbivoresOther heterotrophs9. Which of the following sequences goes from the simplest level to the most complex?Population, community, ecosystemCommunity, ecosystem, populationCommunity, population, ecosystemPopulation, ecosystem, community10. An environment that provides the things the organism needs to live, grow, and reproduce is called its EcosystemHomeHabitatNiche11. An organism that creates its own food is called:A decomposerA consumerA producerA scavenger12. Nonliving parts of the environment such as soil, water, sunlight.AbioticScavengerDecomposersBiotic13. What is an ecosystem?All the interacting organisms that live in an environment and the abiotic parts of the environment that affect the organisms.The relationship among the biotic parts of the environment.A person who observes and studies the interactions between the biotic and abiotic parts of the environment.The relationship between all the abiotic elements of a pond.14. All the living things in an environment such as bacteria, plants, and animals.Limiting factorsFood ChainBioticAutotrophs15. An organism that survives by eating animals. CarnivoreAutotrophProducerPrey16. A group of organisms of the same species living in a particular area at a particular timeEcosystemOrganismCommunityPopulation17. Temperature, light, air, water, soil, and climate are all __________ parts of the environment. LivingBorealBioticAbiotic18. An organism that is killed and eaten by another organismHostFood webParasiticPrey19. All the trees within a forest would be an example of CommunityPopulationEcosystemOrganism20. The largest population of any single species an area can hold that is determined by the available energy, water, oxygen and minerals available as well as by the interaction of organisms (food supply and competition).Ecological NicheEcological SuccessionLimiting FactorCarrying capacity21. A representation of interconnected food chains that show more complex feeding relationships between producers, consumers, and decomposers.EcologyLimiting FactorFood WebBiodiversity22. A subdivision of the environment that includes all living and nonliving portions of the planet. PopulationBiosphereEcological NicheHabitat23. How is an ecosystem different than a community? Ecosystems contain only abiotic factors in an areaNone of theseEcosystems contain both abiotic factors and biotic factors in an areaEcosystems contain only biotic factors in an area24. The graph below shows the changes in the size of the populations of two different species of paramecia placed in one beaker.What can be concluded from this graph?The introduction of paramecium B is followed by a decline in the population of paramecium A.Paramecium B is the predator, paramecium A is the prey.Paramecium B reaches a steady state of growth.Paramecium A is the predator, paramecium B is the prey.25.
