wunder beta🦅 Food Chains
Follow the flow of energy from sun to snake in nature's food chain!
What you’ll learn
- Explain how energy flows from the Sun to plants and then to plant-eating and meat-eating animals.Every food chain begins with the Sun. Plants called producers capture sunlight to make food. Herbivores eat plants and carnivores eat animals, passing energy up the chain, with only a small part of the energy moving to each next step.
- Identify trophic levels, top predators, decomposers, and how food chains connect into food webs.Food chains are built from feeding levels that end with top predators. Decomposers recycle dead matter back into nutrients. In nature, many food chains overlap to form food webs that connect all living things together.
Questions this course answers
Where does the energy in almost every food chain begin?
Nearly all food chains start with the Sun, whose light lets plants make food through photosynthesis.
What do we call living things that make their own food?
Producers, like green plants, make their own food using sunlight, so they are the first link in a food chain.
An animal that eats only plants is called a...
Herbivores, such as rabbits and deer, eat only plants and are the first consumers in a food chain.
In a food chain diagram, which way do the arrows point?
Arrows point from the food to the eater, showing the direction that energy travels up the chain.
What is the main job of decomposers like fungi and bacteria?
Decomposers break down dead plants and animals, returning nutrients to the soil so new plants can grow.
Why are there usually fewer top predators than plant eaters?
About only one tenth of the energy moves to the next level, so there is less energy to support animals at the top.
