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).

Cross between female tiger and male lion: liger

Liger’s cannot have children, they are infertile
