Answer: Alveoli 
Explanation: Alveoli of lungs are surrounded by extensive blood capillaries. The partial pressure of oxygen in the alveoli is higher than the blood entering the pulmonary capillaries, hence oxygen moves into the blood. Carbon dioxide in the lungs simultaneously diffuse out of the blood into the alveolar space.

Humans have an interdependent relationship with other organisms just like organisms in an ecosystem are interdependent.
<h3>How are organisms interdependent?</h3>
To be interdependent means that the involved parties are mutually dependent i.e. they are reliant on one another.
Living organisms in their natural habitat are dependent on one another for food, space, mate and other resources. 
However, humans are also interdependent on other organisms for resources like food, raw materials. For example, we eat plant and flesh derived from other organisms.
