• Life is defined as the set of characteristics that identify living things, including growth, reproduction, and the ability to respond to the environment.
• Producers are living things, such as plants, that make their own food using sunlight, water, and carbon dioxide.
• Consumers are living things, such as animals, that must eat other plants or animals to get energy.
• Internal structures are parts inside an organism, like the heart, lungs, and brain, that help it survive and grow.
• External structures are parts on the outside of an organism, like roots, thorns, stems, and skin, that provide protection or support.
• Senses are the ways animals receive information from the environment, such as seeing, hearing, smelling, tasting, and feeling.
• A plant example is a rose, which has roots to absorb water, a stem to support the plant, and colored petals to attract insects.
• An animal example is a dog, which has skin for protection, lungs to breathe air, and ears to hear sounds.
• Fossils are the preserved remains or traces of ancient living things, like shells in rock layers, that show how landscapes changed over time.
• Vertebrates are animals with a backbone, such as mammals, birds, fish, reptiles, and amphibians.
• Invertebrates are animals without a backbone, such as insects, spiders, and worms.
• Energy is the ability to do work, and it can be transferred from place to place by sound, light, heat, or electric currents.
