Penguins and Ecology

Penguins and Ecology

Hello, let's review the 11th chapter and a very important type of bird today!

Ecology is the study of how animals affect their environment.

Humans have been polluting the ocean in many different ways, and we have only begun to understand how we impact the ocean.

Penguins were once flying birds.

• During the dinosaurian extinction, they learned how to live an aquatic lifestyle.

• Their bones became heavy and their wings became short and stout.

• Penguins, like the Waimanu, started from Australia, and dispersed along the Antarctic circumpolar current to South America, Africa, and Antarctic

• Bathymetry

• Ecology

• Philosophy

• Statistics

Multiple Choice

Which type of penguin originated from Australia?

• Emperor

• King

• Galapagos

• Waimanu

Over time, we have been able to measure different pollutants in the ocean.

We've found pollutants inside of animals and documented how they have accumulated inside of the animals. We've also found that big fish have higher levels of pollutants (biomagnification).

Of the 18 species of penguins, only eight live in Antarctica

• The emperor, king and gentoo penguins are the largest.

• The macaroni are the most numerous.

• The adele, chinstrap and rockhopper are the smallest.
