Ecosystems - Patterns

Patterns

Describe annual and daily patterns and how the environment impacts them.

Activity

Torpor

Deep sleep that is easier to wake up from.

MYTH: Bears hibernate.

FACT: Bears go into torpor.

Bears can sleep for 100 days without eating, drinking, or passing waste. They can turn their urine into protein.

Torpor helps bears avoid danger!

Monarch Butterflies

• Have a special migration to the South in the fall.
• Travel in groups up to thousands.
• Journey about 2,500 miles.
• Requires 3-5 generations of butterflies.

Why do Monarch Butterflies migrate?

LESSON OVERVIEW

• describe population patterns that occur annually
• describe population patterns that occur daily
• evaluate how changes in the environment impact behavior patterns

Nocturnal

Living things active during the night time.

Hibernation

What is an advantage animals that hibernate have over animals that do not?

Circadian Rhythm

Your circadian rhythm is mostly controlled by .

Migration

Desert locusts are herbivorous. Why are swarms like this a threat to humans and ecosystems?

the movement from one place to a different place over long distances

3 reasons for this pattern

Reproduction

Temperature

Food

Humpback whales migrate from equator breeding grounds to feeding grounds at the poles.

Warblers spend winters in Central and South America and Summers in North America.

Desert locusts migrate when their ecosystem becomes overpopulated, in search of more food.

Salmon migrate from ocean to rivers to lay eggs and reproduce.
