Explanation:

To solve the matching, we analyze each number (animal) using the dichotomous key:

For number 1 (snake):

• 1a: Has backbone → Go to 2.
• 2b: No wings → Go to 3.
• 3b: No legs → Name is Carl. So 1 → Carl.

For number 2 (lizard):

• 1a: Has backbone → Go to 2.
• 2b: No wings → Go to 3.
• 3a: Has legs → Go to 4.
• 4b: No shell → Name is Pete. So 2 → Pete.

For number 3 (turtle):

• 1a: Has backbone → Go to 2.
• 2b: No wings → Go to 3.
• 3a: Has legs → Go to 4.
• 4a: Has shell → Name is Larry. So 3 → Larry.

For number 4 (spider):

• 1b: No backbone → Go to 5.
• 5b: No antenna → Name is Chester. So 4 → Chester.

For number 5 (ant):

• 1b: No backbone → Go to 5.
• 5a: Has antenna → Name is Kevin. So 5 → Kevin.

For number 6 (bat):

• 1a: Has backbone → Go to 2.
• 2a: Has wings → Name is Sammy. So 6 → Sammy.
