Both, depending on the size of the nutrient. Much of absorption works through either endocytosis or transport of small molecules by simple diffusion.
Simple diffusion and facilitated diffusion are both types of passive transport and endocytosis requires energy.
Some nutrients are consumed by diffusion and others are actively transported from the digestive tract.
water passively follows salt
If one is bilingual, he or she can communicate actively and passively in (exactly) 2 different languages. Actively involves activities like reading and speaking. Passively involves listening and reading
They react actively rather than passively.

Social control refers to a control that is either exerted passively or actively by an action of a group.
Spinal cord can not move actively. It moves passively along with the vertebral column.
There are 2 types of video cards, actively cooled and passively cooled. Actively means there is a fan mounted on the cooling block which is mounted on the card. Passively means there is no fan and just a cooling block mounted on the video card. Your card could have a passive cooling solution.
Social control refers to the methods and mechanisms used by society to regulate individual behavior and maintain social order. It can be formal (laws, regulations) or informal (social norms, values), and aims to encourage conformity to accepted standards and norms while discouraging deviant behavior.
Aspirin and alcohol are two substances that are actively absorbed in the stomach.
There are 2 types of video cards, actively cooled and passively cooled. Actively means there is a fan mounted on the cooling block which is mounted on the card. Passively means there is no fan and just a cooling block mounted on the video card. Your card could have a passive cooling solution.
Most food absorption takes place in the small intestine. Of the three sections of the small intestine, the duodenum and jejunum absorb the most nutrients. Some nutrients are absorbed in the stomach, but nutrients are absorbed mainly in the small intestine, where the small, soluble molecules are diffused or actively transported from the ileum/duodenum, into the capillaries on the other side of the intestine.
