their environment.2. The regulation of an organism’s environment to

maintain conditions suitable for its survival is called _______________________.

Grow Develop

GrowthLiving materialNew structures

Adjust to changes in the environment

homeostasis

Grow and Develop

Adjust to Changes in Environment – an organisms surroundings

Adaptation-organisms response to its environment

Stimulus –anything that causes an organism to react Response – reaction to a stimulus

Homeostasis- maintaining conditions suitable for survival

Evolution-gradual change in a species over time
