This Grade 5 Science medium worksheet sharpens understanding of native versus invasive species, biodiversity, and habitat fragmentation. Students complete nine fill-ins covering pollinators, wildlife corridors, and protected areas, then match real conservation efforts (bald eagle recovery, Yellowstone wolves, reef sanctuaries, overpasses) with their measurable outcomes. Grade 5 learners practice connecting causes to effects, building the scientific reasoning needed for upper-elementary ecology units, science fair projects, and informed everyday environmental decisions.
Style:
Human Impact on the Environment
Part A: Fill in the Blank
Write the missing word or number on each line.
1. An animal naturally found in a region is called a native species.
2. A species brought from elsewhere that harms local life is invasive.
3. A pathway of habitat linking protected areas is called a corridor.
4. Cutting down forests for farmland is called deforestation.
5. Land set aside by law to protect wildlife is a protected area.
6. The variety of life in a place is called biodiversity.
7. When habitats break into small pieces it is called fragmentation.
8. Bees, butterflies, and bats are important pollinators for many crops.
9. A managed plan to save a threatened species is a conservation program.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
