Arrange these into a food chain and give the trophic level of each: snake, grass, eagle, grasshopper, frog.
Need a reminder? The key ideaShow
A food chain shows who eats whom, starting with a producer. Each step is a trophic level: producers, herbivores, carnivores. Chains link into a food web. Each animal needs many from the level below, so the numbers usually fall at each higher level.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. The chain. grass → grasshopper → frog → snake → eagle.
Step 2. The levels. Grass: first (producer). Grasshopper: second (herbivore). Frog: third. Snake: fourth. Eagle: fifth.
Answer: grass, grasshopper, frog, snake, eagle, at levels one to five.
