This easy-level worksheet has students fix sentence errors, fill in blanks, and write short answers to practice food webs and energy skills.
It includes 9 questions across 3 sections for focused practice.
Style:
Food Webs and Energy
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Consumers make their own food using sunlight and water.
Rewrite: Producers make their own food using sunlight and water. Consumers must eat other organisms to get energy.
2. Fix the sentence:
A food chain has many branching paths where energy can travel in different directions.
Rewrite: A food chain has only one straight path of energy. A food web has many branching paths where energy can travel in different directions.
3. Fix the sentence:
Scavengers hunt and kill live animals to get their energy.
Rewrite: Scavengers eat animals that are already dead rather than hunting live prey.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Energy enters most ecosystems through photosynthesis performed by plants.
2. A primary consumer eats producers like grass or algae.
3. Fungi and bacteria break down dead organisms and are called decomposers.
4. At each level of a food chain, some energy is lost as heat.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Name three types of consumers and explain what each one eats.
Herbivores eat only plants, carnivores eat only animals, and omnivores eat both plants and animals.
2. What might happen to a food web if a disease killed most of the frogs in a pond?
The insects that frogs eat would increase because fewer frogs would be eating them. The snakes and birds that eat frogs would have less food and their numbers might drop.
