Ecosystem Quiz with Answers for Grade 6 Integrated Science

📚 Quick Study Guide

• 🌍 An ecosystem is a community of living organisms (plants, animals, and microbes) interacting with each other and their physical environment (air, water, soil).
• ☀️ The main components of an ecosystem are: biotic (living) and abiotic (non-living) factors.
• 🌿 Biotic factors include all living things like plants, animals, bacteria, and fungi.
• 💧 Abiotic factors include non-living things like sunlight, water, temperature, soil, and air.
• 🍎 Producers (like plants) make their own food through photosynthesis.
• 🐛 Consumers (like animals) eat other organisms for food.
• 🍄 Decomposers (like bacteria and fungi) break down dead organisms and waste, returning nutrients to the soil.
• ⛓️ A food chain shows the flow of energy from one organism to another. For example: grass $\rightarrow$ grasshopper $\rightarrow$ frog $\rightarrow$ snake.
• 🕸️ A food web is a network of interconnected food chains in an ecosystem.
