phototaxis
Movement toward or away from light. Innate.
Phototaxis is the movement or orientation of an organism in response to light sources. It is a biological process that helps in the survival of many organisms. Phototaxis can be positive or negative, depending on the direction of movement.
Positive phototaxis occurs when an organism moves towards a light source. This movement is often seen in single-celled organisms, such as bacteria and algae. These organisms use phototaxis to move towards light sources, which is essential for their survival and growth. Positive phototaxis can also be seen in many animals, such as insects, where they use the light as a guide for navigation.
Negative phototaxis, on the other hand, occurs when an organism moves away from a light source. This type of movement is often seen in nocturnal animals, such as moths and bats, which have adapted to avoid light sources when searching for food or shelter.
In summary, phototaxis is an essential biological process that helps many organisms survive and thrive. It allows them to move towards or away from light sources, depending on their needs.
