B2e - Adaptions Flashcards
How is a killer whale adapted to its cold environment?
The killer whale has a small area to volume ratio, so that it has less area to lose heat from. It has blubber to insulate it, and has find and a muscular tail to help it move faster in the water.
How is an elephant adapted to it’s hot environment?
An elephant has a large surface area to volume ratio, so it has more area to lose heat from - the wrinkled skin and large ears make it easier for the elephant to lose heat from.
How is a freeze thaw frog adapted to its extreme temperature?
The frog has high glucose levels which draw the water out of cells so that they cannot freeze and expand.
How are pine trees adapted?
Leaves are needles to reduce water loss. They have thick wax and few pores so they lose less water.
How is an oak tree adapted to its environment?
The leaves fall in the autumn as there is not much light, so they have no purpose. The have a large surface area to make the most of the summer sun.
How is a cactus adapted to its environment?
Leaves are spines - this reduces water loss and predators are less likely to eat them. They have thick wax to reduce water loss. Their rounded shape reduces surface area to volume ratio so they have a smaller area to lose water.
What is the definition of specialist?
Specific to one habitat
What is the definition of generalist?
Lives in more than one habitat.
