Final answer:
The student is asked to create a pictogram of animals owned by children in a class, but without specific data the task can't be completed. Key characteristics of the animals mentioned include rabbits being lagomorphs, and cats and dogs as carnivores. Completing a pictogram requires data which is not provided.
Step-by-step explanation:
The question pertains to creating a pictogram based on the animals children in a class own, but the necessary data to complete the pictogram (specific numbers of cats, dogs, rabbits, and hamsters) is not provided in the question. A pictogram is a visual tool used in mathematics to represent statistical data. Each icon in a pictogram represents a certain number of units, and so you would need to know the number of each type of animal owned to create a proper pictogram. However, we can discuss the characteristics of the animals listed as that could be relevant to other aspects of the question (though not directly to creating the pictogram).
According to the details provided, rabbits are lagomorphs characterized by long ears, a short tail, and strong hind limbs which allow them to have a bouncing method of locomotion. Hamsters are rodents with continuously growing incisors that require gnawing to be kept short. Cats and dogs are both carnivores with diet and anatomical features adapted to meat-eating.
If the data for the pictogram had been provided, the steps to create the pictogram would include determining the scale (how many animals each picture or icon represents), drawing a picture or icon for each unit, and then labeling the pictogram appropriately to show the numbers for cats, dogs, rabbits, and hamsters owned by the children.
Lastly, when categorizing the list of animals provided into groups based on shared characteristics, rabbits would fit into the Lagomorphs group, mice are rodents, and the likes of cats and dogs can be categorized as carnivores. Kangaroos, mentioned elsewhere in the information provided, would fall into a separate category as they are marsupials.
