They do not have teeth., What are mammals? - Mammals are vertebrates that have hair, which helps keep them warm. They breathe through lungs and feed milk to their young., Explain why most invertebrates are small in size compared to most vertebrates? - Invertebrates are small because they don’t have bones, so their bodies can’t grow as big. There are also many more invertebrates than vertebrates on Earth., Name the groups of invertebrates and explain one of them. - The main groups of invertebrates are jellyfish, worms, mollusks, and arthropods. Explanation: Worms are animals with soft bodies and no legs. For example, earthworms live in the soil and help keep it healthy., Can you name the groups of invertebrates from the greatest number to the least? - Arthropods, mollusks, worms, sea jellies., What are the stages of the life cycle of animals, and can you explain each one? The stages are: - . Birth: Animals are born or hatch. 2. Growth: Animals get bigger. 3. Development: Animals change into adults. 4. Reproduction: Animals produce young. 5. Death: Animals’ lives come to an end. , Animal life cycles start as an ______. - egg, Explain the life cycle of a butterfly. - The first stage is the egg, then it becomes a larva (caterpillar), followed by the pupa (chrysalis), and finally it transforms into an adult butterfly.
