Environmental change

A chameleon’s ability to change color is paramount for survival. In a new habitat, the initial adaptation would involve matching the prevailing colors and patterns of the environment. For instance, a chameleon transitioning from a lush green rainforest to a dry, rocky desert would need to enhance its ability to display browns, grays, and sandy hues.

Thermoregulation

Chameleons are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Adapting to a colder climate would necessitate behavioral changes such as increased basking in sunlight or seeking shelter in warmer microclimates.

The second animal we choose is dogs.

Stimulus

Mark territory

Communication

they'll eat

Stimulus: Touch

Reaction: Leaves fold inward rapidly when touched or shaken.

Why: Defense mechanism to scare off herbivores or reduce water loss.

Stimulus: Touch (specifically mechanical stimulation by insects)

Reaction: Trap snaps shut when trigger hairs are touched twice.

Why: To capture and digest insects for nutrients (especially nitrogen).

Stimulus: Water availability

Reaction: Slow, adaptive growth—store water in thick stems, reduce leaf surface area (spines).

Why: Adapted to survive in extremely dry conditions.

Stimulus: Gravity

Reaction: Roots grow downward, stems upward—strong gravitropic response.

Why: Ensures stability and optimal sunlight exposure.

Stimulus: Light & support

Reaction: Twining stems coil around nearby supports via thigmotropism.

Why: Helps them climb toward light sources.
