Understanding Life Processes

The video explains the essential life processes necessary for living beings to survive, including nutrition, distribution of nutrients, respiration, and excretion. It compares these processes in humans and plants, highlighting the similarities and differences. The video also introduces the technical terms for these processes, such as nutrition, transportation, respiration, and excretion.
