| No it's phytoplankton! |
This
week we have been learning about Whale migration. We've found out that
Humpback Whales spend much of the year in the Southern Ocean around
Antarctica, feeding on krill and other zooplanktons. Then, they migrate
up past New Zealand to the warm tropical waters of the equator to give
birth to baby whales. They stay in the warm waters until the baby whale
(called a 'calf') is fat enough with BLUBBER to
survive the cold waters, before migrating back to Antarctic waters.
We have also been learning about the food chain and the importance of the sun to grow the phytoplanktons. They provide 90% of the world's oxygen! That's amazing !
