The directed movement of a cell or organism towards a source of light. The directed movement of a motile cell or organism towards a higher level of a physical stimulus involved in energy generation, such as light, oxygen, and oxidizable substrates. The directed movement of a motile cell or organism in response to light. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light. The directed movement of a motile cell or organism in response to physical parameters involved in energy generation, such as light, oxygen, and oxidizable substrates.
