Have you ever thought about what you ate yesterday? Maybe you had cereal for breakfast, a sandwich for lunch, and pasta for dinner. Some of our food comes from plants, like cereal and vegetables, while other foods, like chicken or fish, come from animals.
Just like us, animals have different diets. Some animals eat only plants, and we call them herbivores. Imagine cows munching on grass or giraffes reaching high up to eat leaves from trees. Other animals eat only meat, and they are called carnivores. Think of lions hunting in the wild or sharks swimming in the ocean. Then there are animals that eat both plants and meat, and these are called omnivores. Bears and raccoons are good examples because they eat a mix of fruits, fish, and even small animals.
Herbivores have special teeth that help them chew plants. For example, horses have flat teeth for grinding grass, and rabbits have strong front teeth to cut through leaves. Elephants use their trunks to grab food and their big teeth to chew leaves and bark. Giraffes use their long necks to reach tall trees, and zebras have strong teeth to munch on tough grass. These animals help keep plants from growing too much in their homes, which is important for nature.
Carnivores have sharp teeth to help them eat meat. Lions have strong jaws and claws to catch animals like zebras and antelopes. Wolves hunt in groups called packs, which helps them catch bigger animals like deer. Sharks have lots of teeth to catch fish and seals in the ocean. These meat-eating animals help keep the balance in nature by controlling the number of herbivores.
Omnivores can eat many different foods. Bears eat fruits and plants in the spring and summer, and they eat more fish and nuts in the fall to get ready for winter. Raccoons eat fruits, nuts, insects, and sometimes even food from trash cans when they live near people. This ability to eat many kinds of food helps them survive in different places and seasons.
Now, think about some animals you like. Are they herbivores, carnivores, or omnivores? What do their diets tell you about how they live and their role in nature? Talk with your friends and see what you discover!
Animal Diet Detective: Go on a mini adventure in your backyard or a nearby park. Observe any animals you see, like birds, squirrels, or insects. Try to guess if they are herbivores, carnivores, or omnivores based on what they are eating or where they are looking for food. Draw a picture of one animal you observed and write a sentence about what you think it eats.
Create a Food Chain: Use paper, crayons, and scissors to create a simple food chain. Pick an animal you like and think about what it eats and what might eat it. For example, if you choose a rabbit, draw grass, the rabbit, and a fox. Cut out your drawings and arrange them in order to show who eats what. Share your food chain with a family member and explain how each animal is connected.
What’s on Your Plate? At your next meal, look at the food on your plate and try to identify which parts come from plants and which come from animals. Are you eating like an herbivore, carnivore, or omnivore? Write down the foods you eat in a day and categorize them into plant-based or animal-based. Discuss with your family how your diet is similar to or different from the animals you learned about.
Sure! Here’s a sanitized version of the transcript:

[Music] What did you eat for breakfast, lunch, and dinner yesterday? I had oatmeal for breakfast, a chicken sandwich for lunch, and grilled salmon with a side salad for dinner. Notice how some of our food, like oatmeal and vegetables, comes from plants, while foods like chicken, fish, and eggs come from animals.
In the animal kingdom, diet is a primary factor in classification. Animals that eat only plants are called herbivores. Think of cows grazing in a field or giraffes munching on tree leaves. On the other hand, animals that eat only other animals or animal products are called carnivores. Examples include lions hunting in the savannah, snakes feeding on rodents, or sharks in the ocean. Then there are omnivores, which eat both plants and animals. Bears, for example, often eat berries and fruits as well as fish and small mammals. Raccoons also have a varied diet, eating fruits, berries, eggs, insects, and frogs, as well as occasionally scavenging for food in human-populated areas.
Let’s explore these groups further and discuss some more examples to understand their roles in nature. Herbivores like horses have flat teeth designed for grinding leaves and grass. Cows also have wide flat molars perfect for breaking down tough plants, and their complex stomachs help them digest fibrous diets. Rabbits use their strong front teeth to cut through vegetation such as grass and twigs, and their molars help grind up the tough plant fibers they eat. Elephants use their large flat molars to chew a variety of plants, including leaves, twigs, fruit, and bark. Their trunks also help them pick up and eat food. Giraffes reach up with their long necks to eat leaves from tall plants, mainly from acacia trees, chewing them with their ridged molars. Zebras eat different types of grass, and their strong molars are good for grinding up tough plant material. These features help herbivores eat their plant-based diets, which is important for their survival and for keeping plant growth in check within their ecosystems.
Now for a closer look at some well-known carnivores. Carnivorous animals such as lions, wolves, and sharks have specific adaptations that enable them to effectively hunt and consume other animals. These animals often have sharp pointed teeth designed for tearing flesh. Their digestive systems are well-suited to break down meat, allowing them to extract nutrients from their prey. Lions utilize their powerful jaws and sharp claws to take down prey, which includes both small and large mammals in the savannah. They primarily feed on flesh, which provides them with the high-energy nutrients necessary for their active hunting lifestyle. Wolves hunt in packs, allowing them to tackle prey much larger than themselves, such as deer and elk. Their social structure is not only beneficial for hunting but also for raising their young, which are fed meat by the adults. The pack behavior of wolves shows how working together helps them hunt better and take care of their young, which is important for their survival. Sharks, as marine carnivores, have many rows of teeth that make them excellent hunters. Their diet consists mainly of fish, seals, and even larger marine animals, depending on the shark species. The great white shark, for example, is known for its incredible speed and biting power, capable of catching and feeding on a variety of large fish and marine mammals. These carnivorous animals play crucial roles in maintaining the balance of their ecosystems by controlling the population of herbivores and other prey species.
Lastly, let’s look at the diets and habits of a couple of omnivorous animals. Omnivores like bears and raccoons have versatile diets that adapt based on food availability. Bears, for instance, adjust their diet seasonally. In the spring and early summer, they mostly consume fruits, berries, and vegetation. As fall approaches and they prepare for hibernation, their diets shift to include more calorie-dense foods such as nuts, and they increase their intake of protein-rich sources like fish and small mammals. This flexibility in diet helps them maximize their energy intake for survival during the months of hibernation in winter. Raccoons are equally adaptable and known for their opportunistic feeding habits. They eat a variety of foods depending on what is available in natural settings. Their diet includes fruits, nuts, and plants, as well as insects, eggs, and small animals. However, raccoons living near urban areas may also scavenge food from trash bins, showcasing their ability to exploit human environments to supplement their diet. This adaptability allows raccoons to thrive in a wide range of habitats and conditions. Both bears and raccoons demonstrate how omnivores can adjust their eating habits to suit their environmental conditions, which helps them maintain a balanced diet throughout different seasons and varying food availabilities.
