B7- Adaptations Flashcards
What are adaptations?
Features or characteristics that allow organisms to survive in different environments.
Adaptations can include structural, behavioral, and functional changes.
What are structural adaptations?
Features of an organism’s body structure such as shape or color.
Example: Arctic foxes have white fur for camouflage in the snow.
How do Arctic animals like whales adapt to cold environments?
They have a thick layer of blubber and a low surface area to volume ratio to retain heat.
This helps them avoid predators and sneak up on prey.
What adaptations do animals living in hot environments, like camels, have?
A thin layer of fat and a large surface area to volume ratio to help them lose heat.
This adaptation is crucial for thermoregulation in hot climates.
What are behavioral adaptations?
Ways that organisms behave to survive.
Example: Many species, such as swallows, migrate to warmer climates during winter.
What are functional adaptations?
Processes that occur inside an organism’s body related to reproduction and metabolism.
Example: Desert animals conserve water by producing little sweat and concentrated urine.
How do brown bears adapt during winter?
They hibernate and lower their metabolism to conserve energy.
This adaptation allows them to survive when food is scarce.
What are extremophiles?
Microorganisms that are adapted to live in extreme conditions.
Examples include bacteria that can survive in high temperatures, high salt concentrations, or high pressure.
Fill in the blank: Animals that live in cold places have adaptations that help them _______.
retain heat.
True or False: All adaptations are structural.
False.
Adaptations can be structural, behavioral, or functional.
List the three types of adaptations.
- Structural
- Behavioral
- Functional
Fill in the blank: Desert animals conserve water by producing very little _______.
sweat.
