Investigating ecosystems, matter, and energy through hands-on experiments and observations.
All living things need energy to survive. In nature, energy moves from one organism to another through food chains and food webs.
A food chain shows how each living thing gets food. It usually starts with a plant (producer), which is eaten by an animal (consumer), and then maybe by another animal.
Example food chain:
In real life, most animals eat more than one thing. Food webs show how different food chains are connected, making a big, tangled map of who eats whom!
If one part of the food web disappears, it can affect every other part.
A rabbit eats grass, and then a fox eats the rabbit.
Birds eat both seeds and insects, linking different food chains together.
Food chains and webs show how energy flows through living things in an ecosystem.
