Animals and Energy
In this unit we have been learning about different types of energy. This week we will talk about how organisms respond to changes in energy. Some of the common changes in energy that organisms experience are changes in light, sound, and heat. We will learn about how different organisms respond to some of these changes.
What are these butterflies doing?
Monarch butterflies gather in large groups as they migrate 2,500 miles south each fall. They return to the north in the spring. This migration is a cycle that repeats every year.
Cycles of Behavior
Many animal behaviors change in a regular way. They go through cycles. Some cycles of behavior repeat each year. Other cycles of behavior repeat every day. Some of the cycles are influenced by changes in light energy (how much daylight there is), or heat energy (hotter or colder temperatures).
