Detailed explanation-3: -A dog salivating at the smell of food, a flower opening in sunlight and a worm crawling towards moisture are examples of organisms responding to stimuli from their surroundings. All organisms respond to their surroundings in order to improve their chances of survival and reproduction.

Detailed explanation-4: -These interactions are called symbiosis. The impacts of symbiosis can be positive, negative, or neutral for the individuals involved. Organisms often provide resources or services to each other; the interaction is mutually beneficial. These “win-win” symbiotic interactions are known as mutualism (+ +).
