Photokinesis is a big word that means how light affects living things. When you go outside and feel the warm sun on your skin, that's an example of photokinesis. Plants also feel the effects of sunlight. They use a process called photosynthesis to turn the light into energy that helps them grow.
Animals can also be affected by light. Some animals use light to find their way or to hunt for food. Others, like fireflies, use their own light to attract mates.
Scientists study how light affects different living things. They can use special tools to measure the amount of light and how it affects things like animals' behaviors or plants' growth. This helps them understand how light plays a big role in keeping our world healthy and working properly.
