The world is filled with animals, including humans, that need energy to survive. This energy can come from absorbing sunlight or ingesting plants and animals for food. The system that connects all living things and how they obtain energy is known as a food web. For example, grass receives energy from the sun. Gazelles eat the grass, and lions eat the gazelles. Energy is passed from one living thing to the next. Recognizing how organisms in a food web interact with each other helps us understand the delicate balance of nature.
