Exploring the Basics of Photosynthesis

The video explains the difference between heterotrophs and autotrophs. Heterotrophs, like humans and animals, need to consume food for energy. Autotrophs, such as plants, create their own food through photosynthesis, using water, carbon dioxide, and sunlight to produce glucose and oxygen. This process supports life on Earth by providing energy and oxygen for respiration.

What does 'auto' mean in the context of autotrophs?

• Energy

• Food

How do autotrophs produce their own food?

• By absorbing nutrients from the soil

• By using water, carbon dioxide, and sunlight

• By consuming other organisms
