Cosmopolitan distribution

Cosmopolitan distribution means that something (like an animal or plant) is found all over the world in many different places. Imagine if you had toys like Legos and action figures, and you left them all over your house - some on the floor, some on the couch, and some on the table. That's kind of like how some animals and plants are found all over the world - they're scattered in many different places.

For example, think about birds. Some birds only live in one specific place, like penguins who live only near Antarctica. But other birds like seagulls can be found all over the world - they like to go where there is water and food.

Another example is plants like dandelions. They're a little weed that grows all over the world, from North America to Europe and Asia. They're not picky and can grow in lots of different places, just like seagulls.

So, when we say something has a cosmopolitan distribution, it means that it's found all over the world in lots of different places. It's kind of like leaving your toys all over the house, rather than just in one specific toy box.
