1. The answer is: Ben is correct because the plant leaning towards the light is a behavior that the plant has learned in order to survive.
A plant needs sun light in order to conduct a photosynthesis to produce its food. When the plant is placed in sheltered location (such as kitchen, bedrooms, or warehouse), it would start to adapt and lean its body so it can be closer to the sun.
2. migrate
A lot of birds do not have the physical features to survive in the cold environment. Because of this, during winter seasons, birds would fly across the world to the region that still has warm climate. This is a form of behavioral adaptation that they learn to help them survive.
3. This is a behavioral adaptation because it is an action that the plant performs in order to survive.
A Venus fly trap obtain the foods from insects' meat. Since it does not have the ability to move, it undergone a behavioral adaptation to directly close it leaves every time an insects land on top of it. This would make the insects become trapped and the plant could digest the insects for their nutrients.
