Equator
• At Equator:
• Therefore: Air flows in from the sides. WIND
• The rising air eventually and flows to the .• Away from the equator:

CLASSIFICATION OF LIVING ORGANISMS
• Classification: an orderly grouping of organisms according to selected criteria
• The study of classifying organisms is called taxonomy– Provides universal names for organisms– Provides a reference for identifying organisms
Living organisms
Divided into six Kingdoms

Two individuals belong to the same species if …
• They share similar characteristics,– for example physical resemblance
• They can reproduce (if of opposing sex), • The children of these two individuals are
viable (survive),• the children themselves can reproduce
successfully (they are fertile).

Liger’s cannot have children, they are infertile
