Studying Earth systems, energy transfer, and the scientific method for fourth grade students.
All living things need energy, and they get it from food! A food chain shows how energy passes from one living thing to another.
An ecosystem is all the living and non-living things in a place and how they interact. Every part of an ecosystem depends on the others, like a team working together.
If one part of a food chain or ecosystem is changed, it can affect everything else!
A rabbit eats grass, and a fox eats the rabbit—energy moves from plants to animals.
A pond ecosystem with plants, fish, insects, and birds working together.
Food chains show how energy moves through living things in ecosystems.
