​Tall height is an adaptation of sunflowers to help them compete for sunlight. They have this adaptation because they need sunlight (a resource) to survive.

​​Being tall

Could you spot this cheetah from far away? This is an adaptation to have a better chance to sneak up on food like you to survive. (Jk...not)
