1. What are grasslands

and prairies ?

 

Look at these pictures.  Can you see why these are called grasslands?

The kind of grassland we have in America are called prairies.

Prairies have cold winters and hot summers with a moderate amount of rain and snowfall

The soil is rich and fertile; that means it is good for growing plants. 

The fertile soil is a nonliving component of the prairie ecosystem.

2. What are some special features of prairie life?

 

You may have noticed that there are not a lot of places for little creatures to hide from predators.  Many prairie animals have front legs and paws that allow them to dig underground so they can stay safe from predators.

Look at the claws on this badger!

Another adaptation is the color of fur and skin. 

Many of the animals blend with the prairie landscape.

 

3. What kinds of animals live there?

 

With all that grass this is a great place for herbivores! Some herbivores that live on the prairie are:

  Black-tailed Jack Rabbit
prairie dogs bison elk jackrabbit

But there are also carnivores:

coyote fox kingsnake owl
