Students complete nine fill-in-the-blank problems about biotic and abiotic factor vocabulary and food web connections. The matching activity pairs sunlight, fungi, soil, and oak tree with their biotic or abiotic labels and ecosystem roles.
Matching specific ecosystem factors to biotic or abiotic categories and their roles consolidates both vocabulary and reasoning — showing that each component has a distinct function in the ecosystem.
Style:
Ecosystems
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Living things in an ecosystem such as plants and animals are called biotic factors.
2. Non-living things like water, sunlight, and soil are called abiotic factors.
3. A food web shows many overlapping food chains in one ecosystem.
4. Temperature is an abiotic factor that affects which organisms can survive in an area.
5. Bacteria in the soil are biotic factors because they are living organisms.
6. A food web is more complex than a single food chain because it shows all feeding links.
7. If one species disappears from a food web, other species that depend on it are affected.
8. The amount of rainfall an area receives determines what types of plants can grow there.
9. An ecosystem includes both biotic and abiotic factors working together as a system.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Sunlight
→ Abiotic — provides energy that producers need to make food
Abiotic — provides minerals and a place for roots to grow
Fungi
→ Biotic — breaks down dead matter and recycles nutrients
Biotic — breaks down dead matter and recycles nutrients
Soil
→ Abiotic — provides minerals and a place for roots to grow
Biotic — produces acorns and oxygen through photosynthesis
Oak tree
→ Biotic — produces acorns and oxygen through photosynthesis
Abiotic — provides energy that producers need to make food
