Why is classification needed?
Human classification-
Species-homo sapiens, members of the genus homo with a high forehead and thin skull bones.
Genus-homo, hominids with upright posture and large brains.
Family-hominids with relatively flat faces and 3 dimensional vision.
Order-primates, mammals with collar bones and grasping fingers.
Definition:
Frozen seawater (not from glacier) it's a shifting puzzle of ice slabs that grow in winter and shrinks summer.
The Ecosystem:
It acts as a floating forest. Algae grow inside the ice feeding tiny shrimp which then feed the entire food chain.
Who lives there?:
• Polar bears-use ice as a "floor" to hunt seals.
MANGROVE FOREST-
Definition and location:
Salt tolerant trees and shrubs that grow in the intertial zone. (Where land meets the sea).
Water type- Found in the brackish water. ( Mix of fresh and salt.)
Climate change- Tropical and subtropical regions, ( they need warmth).
Key adaptations:
Deserts are a very harsh place to live in as there is very less rainfall, so animals and plants adapt to their surroundings.
An example of desert plants are Saguaro cacti and the an example of desert animals are Gila woodpeckers, they make holes in the cacti to make their nest.
Cactus wrens often used a different kind of cactus called Teddy bear cholla.
They are very spiky that very few other animals come close to them so that their eggs are protected.
Lizards and tortoise and other animals rst in shade of plants or burrow into the soil because it is cooler.
At night when it is cold, kangaroos come out to feed, wary of their predators such as rattlesnakes and coyotes.
