Exploring the Animal Kingdom

Slide 1

Welcome to Biology!

What is biology? It's the study of all living things, from tiny bacteria to giant whales. Biologists explore how living things grow, interact, and survive in their environments. Understanding biology helps us understand our own bodies and the world around us. Let's start our journey into the amazing world of animals!

Slide 2

What Makes an Animal? Basic Characteristics

Animals share some key characteristics that set them apart from plants or fungi. They are multicellular, meaning they are made of many cells. Animals are heterotrophs, which means they must eat other organisms to get energy. Most animals can move, especially to find food or escape danger. They also reproduce sexually, creating new generations.

Slide 3

Classifying Animals: Vertebrates vs. Invertebrates

Scientists group animals into categories based on shared features. One of the biggest divisions in the animal kingdom is whether an animal has a backbone or not. Animals with a backbone are called vertebrates. Animals without a backbone are called invertebrates. This simple difference helps us organize millions of species!

Slide 4

Vertebrates: Animals with Backbones

Vertebrates have an internal skeleton, including a backbone (or spinal column), which provides support and protection. There are five main groups of vertebrates: fish, amphibians, reptiles, birds, and mammals. Each group has unique adaptations, like fins for fish, feathers for birds, or fur for mammals.

Slide 5

Invertebrates: Animals without Backbones

Invertebrates make up about 95% of all animal species! They are incredibly diverse and include insects, spiders, worms, jellyfish, snails, and sponges. Many invertebrates have exoskeletons (hard outer coverings) for protection, while others have soft bodies. They live in every habitat on Earth, playing vital roles in ecosystems.
