Understanding Biodiversity and its Importance Question Type Multiple choice Which of the following BEST describes the importance of 2 biodiversity within an ecosystem Possible Answer B Biodiversity increases ecosystem stability and resilience by providing a greater range of species to adapt to changing conditions Explanation Think of a forest A diverse forest with many tree species different insects and various animal populations is far more resilient to disease or climate change than a monoculture of a single tree species The variety acts as a buffer ensuring the ecosystem can withstand shocks 2 Food Webs and Trophic Levels Question Type Short answer Describe the role of decomposers in a food web Possible Answer Brelated Decomposers like bacteria and fungi break down dead organic matter recycling nutrients back into the ecosystem making them essential for nutrient cycling They are vital for the continuation of the food web Explanation Picture a fallen log in a forest Decomposers are the unsung heroes breaking down the wood releasing nutrients into the soil which then nourish new plants fueling the entire food web They are not at the top of the food chain but are fundamentally important 3 Symbiotic Relationships Question Type Matching Match the symbiotic relationship with its description Possible Answer Brelated Parasitism One organism benefits while the other is harmed Explanation Think of a tick on a dog The tick parasite benefits by feeding on the dogs blood while the dog host is harmed by the loss of blood and potential disease transmission Understanding different types of symbiosis mutualism commensalism parasitism is crucial 4 Habitat Loss and Fragmentation Question Type Essay Discuss the impact of habitat fragmentation on biodiversity Possible Answer Brelated Habitat fragmentation isolates populations reducing gene flow and making them more vulnerable to extinction It also reduces the overall size of available habitat further threatening species survival Explanation Imagine a forest being divided into smaller patches by roads or development Animals cant move freely between patches leading to smaller isolated populations This reduces genetic diversity and makes them more susceptible to disease and environmental changes 5 Human Impact on Ecosystems Question Type Multiple Choice Which human activity is the biggest
