Answer 1

Explanation:

HEY MATE HERE IS YOUR ANSWER

A tropism is the innate ability of an organism to turn or move in response to a stimulus. As opposed to a learned ability, innate reactions are genetically programmed. Organisms with a tropism will naturally turn toward a stimulus. A stimulus can be any signal from the environment, and individual tropisms are often named after the stimulus that causes the movement. In a positive tropism the animal will move toward the stimulus. In a negative tropism, the animal will move away from the tropism. Certain stimuli become genetically engrained because they are always beneficial or always detrimental to an organism. A movements caused by a tropism is called a taxis.
