Essential Needs of Living Things

The video explains the basic needs of all living organisms, including water, energy, living space, and homeostasis. It discusses how different organisms meet these needs, such as plants using photosynthesis and animals consuming food. The concept of homeostasis is introduced, highlighting how organisms maintain stable internal conditions despite external changes. The video concludes with a recap of these essential needs.
