Eco is a young explorer who loves to learn about nature. Today, Eco is starting an incredible journey to discover the different ecosystems of the world. He wants to learn how people live, animals and plants in different places on Earth.

Eco wants to visit the tropical jungle. He realizes that the air is hot and humid. In the jungle, he sees that there are many trees, and they are very tall.  He ventures into the jungle to discover its inhabitants.  He hears the birds sing and also meets a jaguar, a colorful toucan and a beautiful orchid growing on the trees.

Without the rain, the jungle wouldn't be so green. We all depend on her!

Suddenly It started to rain, and he realized that in a tropical jungle it rains a lot, and that's why the plants are so tall, green and strong.

Why do you think I can not find water?

Eco wants to visit more places and heads to see the desert. The sun shines and there is sand everywhere. He looks for water, but he cannot find it.

I keep water in my body.

How do you live in the desert with so little water?

Eco meets a camel that walks slowly on the dunes.

Can you tell me the characteristics of the desert climate?

When it became night, Eco felt very cold. He realized that during the day it is very hot, but at night it is very cold. 

How do they survive in this cold place?

We have thick fur and feathers to keep us warm.

Eco travels north, to  the tundra. The ground is covered with snow, and the air is frozen. Meet a polar bear and a snowy owl.  

Why are all animals white or gray?

This helps us stay safe from predators and hunt for food. We blend in with the snow.

Eco notices that the animals in the tundra are white or gray.

The next place Eco wants to visit is the ocean. So, Eco dives in the ocean. He notices that the water is deep and blue. When he was swimming, he found dolphins, turtles and schools of fish.
