Based on my analysis of the worksheet and biological classification principles, I can now provide the complete solution:
Solution for Q1: Label the diagram
The two main branches should be labeled as follows:
- Left box (animals that "have a backbone"):
Vertebrates
- Right box (animals that "don't have a backbone"):
Invertebrates
The animals shown under the "have a backbone" branch (cow, bird, fish, snake, frog) are all vertebrates, which confirms this classification.
Solution for Q2: Fill in the blanks
a) All living things are classified into
five main groups called kingdoms.
*(Note: While some modern systems use three domains or six kingdoms, the traditional five-kingdom system - Monera, Protista, Fungi, Plantae, Animalia - is still commonly taught at this level.)*
b) The two main groups of animals are
vertebrates and
invertebrates.
*(This directly corresponds to the classification shown in Q1.)*
c) Vertebrates have
bones (or more specifically, a
backbone or
spine) inside their bodies.
*(The defining characteristic of vertebrates is the presence of a vertebral column or backbone.)*
This completes the worksheet by correctly labeling the classification diagram and filling in the blanks with appropriate biological terms.
Parent Tip: Review the logic above to help your child master the concept of animal classification worksheet middle school.
