Grassland food chain

A grassland food chain follows one possible route for energy through an ecosystem. Sunlight supports grass, the producer. A grasshopper eats the grass, then a frog eats the grasshopper, a snake eats the frog, and a hawk eats the snake. The arrows point from the organism being eaten toward the consumer, which shows the direction energy moves. Decomposers receive organic matter from organisms that die and return nutrients to the ecosystem. This is a simplified chain: real grasslands contain many overlapping feeding relationships. Use it to introduce trophic levels before expanding the lesson into a food web.

O que há neste desenho

Entenda as decisões por trás dele.

01Producer first

Begin with sunlight and grass.

02Consumer order

Arrange animals from herbivore to top predator.

03Energy direction

Point arrows from food to consumer.

04Decomposition

Add decomposers for dead organisms.

Use this chain for a classroom example of energy transfer in a temperate grassland.

Perguntas frequentes

Dúvidas comuns

What is the producer in this chain?

Grass is the producer because it uses sunlight to make its own food.

Which way should food-chain arrows point?

Point arrows from the food source toward the organism that receives the energy.

Why include decomposers?

They break down dead organic matter and help return nutrients to the ecosystem.
