Pre-Trip Activities Nature consists of millions of plants and animals. Each differs in size, shape, texture, and behavior. The goal of this unit is to help the students to better understand each living thing's place in nature, and the notion that nature is sustained through a web of life and death called a food chain. A plant is an organism that is rooted to one place. There are many different groups of plants.
Some examples are trees, flowers, or grasses.
An animal is able to move around on its own power. It gets its food from other living or once-living things. It breathes in oxygen and breathes out carbon dioxide. With proper homes and food, they can still function in cold winter temperatures. We are warm-blooded animals.
