Animal Adaptations A stimulus is a type of information that has the potential to make an organism change its behavior. Ex. Hunger signals, thirst, sound of a predator

Movement related behaviors Kinesis – an increase in random movement that lasts until a favorable environment is reached. Taxis – movement in a specific direction either toward or away from a stimulus

Behavioral Adaptations Inherited traits that help an organism survive and reproduce in a given environment; a behavior, response, or action (ex: living in hunting groups)

Structural Adaptations Traits that involve the physical structure or anatomy of an organism (ex: quills of porcupine; mimicry, camouflage, etc

Some other structural adaptations are subtle…..MIMICRY Mimicry enables one species to resemble another species. THE MOTH, LEAF INSECT, & STICK BUG ARE GREAT EXAMPLES OF MIMICRY!!!

Three Types of Animal Adaptations: Traits that involve the internal functions or chemistry of an organism (ex: weeds resistant to pesticides, bacteria resistant to antibiotics, etc.) Think…”Chemical” or “enzyme”

Bees communicate with each other to locate nearby pollen

Opossums…the only marsupial in the US Opossums…the only marsupial in the US!! Typically play dead when frightened… Or Physiological- because it is a chemical within the body that helps it to lie so still.

Plant responses(22.5) Tropism – the movement of a plant in response to an environmental stimulus. Phototropism – the tendency of a plant to grow toward light.

Thigmotropism – a plant’s response to touch. For example, climbing plants and vines.

Gravitropism – The vertical, or up and down, growth of a plant in response to Earth’s gravity. Positive tropism – downward growth in the direction of gravity’s pull. Negative tropism – upward growth against the force of gravity.
