What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Who eats whom in the Antarctic ocean?

The Big Idea

In the Antarctic ocean, almost everyone eats or is eaten, starting with tiny plants! Krill sit in the middle of the whole web. They are the center of almost everything. Let's follow the food!

Tiny Plants

Step one: tiny plants. Tiny plants called phytoplankton make food from sunlight. Krill graze on them, so energy moves up the web, from one hungry mouth to the next.

Krill Eaters

Step two: krill eaters. Krill feed penguins, seals, fish, squid, and baleen whales. Krill are in the middle of almost everything, which makes them the center of the web.

Top Hunters

Step three: animals at the top. Larger seals and orcas are at the top. Many food chains weave together like a net, so we call it a food web.

A Closer Look

Let's take a closer look! It starts with tiny plants floating in the sunlit water. Krill eat the plants. Penguins and seals eat krill and fish. Whales and orcas are at the top.

Quick Facts

Quick facts! A food web has many links, not just one chain. If one link changes, the others can feel it. Arrows in a food web point from the food to the eater. Be kind to ocean animals everywhere, and take care of their home.

Think Like a Scientist

Now, think like a scientist! Draw the food web on paper, with arrows pointing from food to eater. Use krill, penguin, seal, whale, and fish. Can you find the center of the web? Share what you discover with a grown-up.

Outro

Krill sit at the center of the Antarctic food web. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
