Students explore how living and nonliving things depend on each other. Part A's nine fill-ins cover bees spreading pollen, animals breathing out carbon dioxide, secondary consumers like frogs eating insects, abiotic and biotic factors, sunlight powering photosynthesis, deciduous forests, and earthworms creating air spaces in soil. Part B is a four-pair matching set linking habitat features — frozen ground, heavy daily rain, tall grasses, sand dunes and cacti — to tundra, rainforest, grassland, and desert biomes.
These connections help third graders see ecosystems as webs of dependence, not just lists of animals.
Style:
Habitats and Ecosystems
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Bees help flowers by spreading pollen from plant to plant.
2. When animals breathe out, they release carbon dioxide that plants need.
3. A secondary consumer eats primary consumers, like a frog eating insects.
4. The nonliving parts of an ecosystem are called abiotic factors.
5. Trees provide shelter and food for many forest animals.
6. Without sunlight, plants cannot make food through photosynthesis.
7. An ecosystem where trees lose their leaves each fall is a deciduous forest.
8. Earthworms improve soil by creating air spaces as they dig tunnels.
9. The living parts of an ecosystem are called biotic factors.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each habitat feature to its correct biome.
frozen ground year-round
→ tundra
grassland
very heavy daily rainfall
→ rainforest
desert
tall grasses and few trees
→ grassland
tundra
sand dunes and cacti
→ desert
rainforest
