- Q1What is an ecosystem?A community of organisms interacting with each other and their physical environmentA group of animals living togetherA collection of bodies of waterA region with diverse plant species30s
- Q2What is the process through which plants convert sunlight, carbon dioxide, and water into glucose and oxygen?RespirationFertilizationPollinationPhotosynthesis30s
- Q3What is biodiversity?The genetic makeup of an individual organismThe variety of life in a particular ecosystem or on Earth as a wholeThe number of different species in a specific habitatThe total population of a species in a specific area30s
- Q4What is a food chain?A hierarchical series of organisms in an ecosystem, where each member is dependent on the one below it for foodA cycle of nutrient exchange in an ecosystemThe migration patterns of animalsThe movement of energy in an ecosystem30s
- Q5What is the role of decomposers in an ecosystem?Pollinating flowers to aid in reproductionProducing oxygen through photosynthesisHunting and consuming other organisms for foodBreaking down dead organic matter and returning nutrients to the soil30s
- Q6What is a producer in an ecosystem?An organism that converts sunlight into energy through photosynthesisAn organism that only feeds on plantsAn organism that decomposes dead organic matterAn organism that consumes other organisms for energy30s
- Q7Which of the following organisms is an example of a decomposer in an ecosystem?SharkGrassButterflyFungi30s
- Q8Which of the following organisms is an example of a consumer in an ecosystem?MushroomSunflowerCactusWolf30s
- Q9Which of the following organisms is an example of a producer in an ecosystem?OwlSnakeBearGrass30s
- Q10What is the role of a consumer in an ecosystem?To convert sunlight into energy through photosynthesisTo decompose waste materialTo break down dead organic matterTo obtain energy by consuming other organisms30s
- Q11Which of the following is an example of a producer in an aquatic ecosystem?AlgaeOctopusDolphinShark30s
- Q12Which of the following is NOT a producer in a food chain?FernsFoxGrassAlgae30s
- Q13What is a food web?The process of converting sunlight into chemical energy.A single path of energy flow in an ecosystem.The sequence of predators and prey in an ecosystem.A complex network of interconnected food chains.The transfer of energy between trophic levels.30s
- Q14What is the primary source of energy in most ecosystems?SunSoilAirWater30s
- Q15What is the difference between a food chain and a food web?A food chain is a linear sequence of organisms, while a food web is a complex network of interconnected food chains.A food chain includes only predators and prey, while a food web includes all organisms in an ecosystem.A food chain shows the flow of energy, while a food web shows the flow of matter.A food chain consists of producers only, while a food web includes consumers.A food chain represents a single trophic level, while a food web represents multiple trophic levels.30s
