- Q1What is ecological succession?A process of relocating species from one ecosystem to another.A sudden catastrophic event in an ecosystem.A process of genetic modification in organisms.A process of gradual change in an ecosystem over time.30s
- Q2What is a climax community in ecological succession?A stable and mature community that remains relatively unchanged until disrupted by a disturbance.A temporary community that forms after a disturbance and precedes the establishment of a stable community.The process of one community replacing another in an ecosystem.The gradual process of changes that occur in an ecosystem over time.The initial colonization of organisms in a barren area.30s
- Q3What is the role of pioneer species in ecological succession?They are the final stage of ecological succession.They are the top predators in a mature community.They are the first organisms to colonize a barren or disturbed area.They accelerate the process of disturbance in an ecosystem.They are responsible for the decomposition of organic matter.30s
- Q4What is primary succession?A process of genetic modification in organisms.A process of ecological succession that occurs in an area where no life previously existed.A process of relocating species from one ecosystem to another.A sudden catastrophic event in an ecosystem.30s
- Q5What is the role of secondary succession in ecological processes?To restore ecosystems to their pre-disturbance state.To accelerate the process of disturbance in an ecosystem.To create new ecosystems in areas where no life existed before.To introduce non-native species into an ecosystem.30s
- Q6What is an example of primary succession?The invasion of an ecosystem by non-native species.The recovery of coral reefs after a bleaching event.The regrowth of vegetation after a forest fire.The colonization of a lava flow from a volcanic eruption.30s
- Q7What is a pioneer species in ecological succession?Species that migrate between different ecosystems.The first species to colonize a barren or disturbed area.The final stage of ecological succession.The top carnivores in an ecosystem.The dominant species in a mature community.30s
- Q8What is secondary succession?A process of ecological succession that occurs in an area that already had life but has been disturbed or disrupted.A process of genetic modification in organisms.A process of relocating species from one ecosystem to another.A sudden catastrophic event in an ecosystem.30s
- Q9Which of the following is a characteristic of primary succession?An established ecosystem is destroyed by a natural disaster.A barren land is colonized by pioneer species.A secondary succession occurs after a wildfire.A climax community is present from the beginning.30s
- Q10Which of the following is an example of a pioneer species in primary succession?SquirrelMaple treeLichensDeer30s
- Q11Which of the following is not a factor that affects primary succession?Availability of sunlightPresence of pioneer speciesSoil fertilityClimate30s
- Q12What is the initial source of soil in primary succession?Deposition of sediment from water bodiesWeathering of rocksDecomposition of organic matterNutrient runoff from nearby areas30s
- Q13What is the primary driver of primary succession?Human interventionAbsence of lifeClimate changePresence of pioneer species30s
- Q14What is an example of a pioneer species in primary succession?Maple treeSquirrelDeerLichens30s
- Q15Which of the following is a key difference between primary succession and secondary succession?Primary succession involves the colonization of pioneer species, while secondary succession involves the regrowth of existing species.Primary succession occurs after a wildfire, while secondary succession occurs after a volcanic eruption.Primary succession occurs on lifeless or barren land, while secondary succession occurs on a previously established ecosystem.Primary succession leads to the formation of a climax community, while secondary succession leads to the destruction of a climax community.30s
