Living and Non-Living Things — Important Questions

Movement

When a sunflower turns its face towards the Sun, it is showing movement. Plants also show movement, even though they cannot walk. The sunflower moves to get more sunlight. This is different from reproduction (making babies), breathing (taking in air), or feeding (getting food).

Photosynthesis

Green plants make their own food using water, air, and sunlight through a process called photosynthesis. Digestion is breaking down food in the stomach. Reproduction means making babies. Respiration means breathing. Only photosynthesis is the food-making process in plants.

Frog

Frogs move by hopping using their strong back legs. Fish swim in water. Birds fly in the air. Tigers walk and run on land. Each animal has its own special way of moving.

Lifespan

The period of time that a living thing lives is called its lifespan. For example, a butterfly has a lifespan of 20–30 days and a dog has a lifespan of 10–14 years. Non-living things like stones and chairs do not usually have a lifespan.
