ClassX Video Lessons Youtube Channel Smile and Learn English FOOD CHAINS for Kids ???? Green and Brown ???? Episode 3
Hi everyone! How are you doing today? Imagine this: you’re super hungry after a long day at school. You get home and ask your dad, “What’s for dinner?” What if he said, “dead stuff”? Yikes! But guess what? The food we eat isn’t too far from things that were once alive or even waste. That’s what we’re going to learn about today!
Do you remember what a food chain is? A food chain shows how living things are connected by what they eat. We’ve learned about food chains in water and on land, but did you know there’s another way to look at them? Let’s explore!
Green food chains, also known as predator or grazing food chains, start with something called a producer. Producers are living plants that make their own food using sunlight through a process called photosynthesis. That’s why they’re called “green” food chains—because they start with green plants like grass.
Brown food chains, or detritus food chains, are a bit different. They don’t start with living plants; they begin with dead things. How does that work? Well, when plants and animals die, they leave behind remains like leaves, branches, or even animal bodies. These remains are called detritus, and they form the first level of brown food chains.
For example, imagine a worm munching on some dead leaves. Then, a chicken eats the worm, and later, a person eats the chicken. See? Even though we might not eat dead stuff directly, the animals we eat might have!
Brown food chains are super important for our planet. Did you know that 90% of the food chains on Earth are brown? That’s a lot! When a whale dies and sinks to the ocean floor, it creates a food chain that can last for a long time. Tiny creatures like crabs eat the whale’s remains, then fish eat the crabs, and so on. It’s like a never-ending cycle!
So, remember: green food chains start with living plants, and brown food chains start with dead matter like plant remains or animal remains.
Great job learning about food chains! Even if you don’t want to eat dead stuff for dinner, the animals we eat might have eaten something that was once alive or dead. Isn’t it fascinating? Now you know there are many ways to look at food chains. Keep exploring and learning!

Food Chain Detective: Go on a nature walk in your backyard or a nearby park. Look for different plants and animals. Try to identify a simple food chain by observing who might eat whom. For example, you might see a plant (producer), an insect eating the plant, and a bird that might eat the insect. Draw a picture of your food chain and share it with your family or friends.
Build a Food Chain Model: Using craft materials like paper, scissors, and glue, create a 3D model of a food chain. You can use green paper for plants, and cut out shapes to represent different animals. Arrange them in order from producers to consumers. Explain your model to someone at home, describing how energy moves from one level to the next.
Food Chain Story Time: Write a short story about a day in the life of an animal in a food chain. Choose an animal, like a worm or a bird, and describe what it eats and what might eat it. Think about how it fits into either a green or brown food chain. Share your story with your class or family and discuss how each part of the food chain is important.
Sure! Here’s a sanitized version of the transcript:

Smile and Learn! Hi everyone, how is it going? Imagine this situation: you are very hungry after a long day at school. You get home and see that Dad is in the kitchen preparing something, so you ask, “Hey Dad, what’s for dinner?” What would you think if he said, “dead stuff”? Oh my gosh! Believe it or not, the food we eat is not far removed from dead things or even waste. That’s what we’re going to talk about today.
But first, do you remember what a food chain is? A food chain is a process that shows how living things are connected by what they eat. We have already learned to classify aquatic and terrestrial food chains, but did you know that there’s another way to classify food chains? Let’s find out more about it!
**Green Food Chains**
We have already seen many green food chains, also called predator food chains or grazing food chains. The first level of these food chains is a producer, which is alive and makes its own food through photosynthesis. That’s where the name “green food chain” comes from because these producers are alive and green, like grass or any other living plant.
**Brown Food Chains**
On the other hand, brown food chains, also called detritus food chains, don’t start with living plants; they start with, you guessed it, dead matter. How is this possible? Well, you know that all living things die. For example, many plants are never eaten while they’re alive; they live a long and happy life and then die, leaving their remains. Have you ever gone for a walk in the park in autumn? If you look at the ground, you’ll see a lot of dead plant remains like leaves, branches, and even roots. We call these remains detritus or dead matter, and they form the first level of brown food chains.
Here we can see a hungry worm eating some delicious detritus. Then a chicken eats the worm, and later a human eats the chicken. Wow! See, we’re not too far removed from dead things in brown food chains. Brown food chains are extremely important for sustaining the Earth’s ecosystems. In fact, 90% of the food chains on Earth are brown. Amazing, right?
Did you know that when a whale dies and sinks to the bottom of the ocean, it creates food chains that can exist for months or even years? It’s all because of the whale’s detritus. This is what happens: the whale lives a long and happy life and then dies. The whale’s body is converted into detritus with the help of bacteria and fungi in the water. Then other living creatures, like crabs, eat that detritus. Then a fish eats one of those crabs, an octopus eats the fish, and a shark eats the octopus. Later, the shark dies, sinks to the bottom of the ocean, and with the help of those bacteria and fungi, becomes, you guessed it, detritus—a meal for a hungry crab. And so the brown food chain starts all over again. Pretty incredible, isn’t it?
Remember that green food chains start with living plants, and brown food chains start with dead matter such as plant remains, animal remains, or even waste.
Great work! You’ve done a super job! So even if you don’t really feel like eating dead stuff for dinner, the animals we eat or the ones they eat sure do! Aren’t food chains interesting? Now we know that there are many ways to classify them. Bon appétit! See you next time!
