Grade 5 learners examine human impact on food webs in this rigorous science worksheet. Multiple-choice items cover habitat destruction, pollution, and invasive species, while fill-in items reinforce vocabulary like biodiversity and equilibrium. Students think about how protected parks, clean water, and native plants keep food webs strong. Hints guide reasoning about cause and effect, helping Grade 5 students plan ways to protect ecosystems and the species that share them.

Part A: Multiple Choice
Circle the best answer for each question.
1. Which human action removes homes for many Grade 5 ecosystem animals?
A) Clearing forests for farms and cities
B) Planting more native trees
C) Setting up wildlife reserves
D) Cleaning trash from rivers
2. What is an invasive species?
A) A non-native species that harms local food webs
B) Any animal born in a forest
C) A plant that only grows in deserts
D) A predator that lives in zoos
3. How does water pollution affect a pond food web?
A) It can poison producers and harm consumers up the chain
B) It always makes more fish appear
C) It turns ponds into deserts overnight
D) It only affects birds in the sky
4. Which action best protects food-web biodiversity?
A) Creating protected parks and wildlife reserves
B) Filling wetlands with concrete
C) Releasing pet snakes into local forests
D) Dumping factory waste into streams
Part B: Fill in the Blank
Write the correct answer on each line.
1. When people cut forests for cities, this is called habitat destruction.
2. Chemicals from factories that harm rivers are a form of pollution.
3. A non-native species that harms local food webs is called invasive.
4. The variety of species in an ecosystem is called biodiversity.
5. When food webs lose species and stop balancing, they fall out of equilibrium.
