Worksheet Overview

QUESTION 1 of 10

There are many types of animals that have teeth. Fish have teeth, and so do lizards, snakes and frogs. These animals generally have small, pointed teeth that are used for biting but not for chewing.

 

Mammals (like bears, lions, horses and humans) have teeth too. Unlike other animals, mammals have a variety of teeth that are used for different purposes.

 

The type of teeth they have can tell you a lot about the types of food that they eat.

Humans have three different kinds of teeth. Can you match each tooth with its use?

 

Column A

Column B

B: incisor
grinding
C: canine
cutting
A: molar
tearing

Look at these animals and try to match each one with the type of diet it is suited to.

  • Question 1

Humans have three different kinds of teeth. Can you match each tooth with its use?

 

CORRECT ANSWER

Column A

Column B

B: incisor
cutting
C: canine
tearing
A: molar
grinding
EDDIE SAYS
Incisors are sharp,blade like teeth that are good for biting and cutting.
Molars are flat topped teeth that are good for chewing and grinding.
Canines are pointed teeth that are good for holding and tearing.
  • Question 2

Look at these animals and try to match each one with the type of diet it is suited to.

 

 

 

CORRECT ANSWER

Column A

Column B

bear
meat eater (carnivore)
horse
plant eater (herbivore)
human
mixed diet (omnivore)
EDDIE SAYS
The bear has sharp canine teeth, good for catching and biting its prey, and big incisors, good for taking the meat from bones. The carnassial teeth at the back are like shears that can crunch bone.
The horse has blade-like incisors that are good for snipping grass and other plants, and flat topped cheek teeth that are good for grinding tough plant material.
Human teeth are good for biting and chewing and are somewhere between those of a meat and plant eater.
  • Question 3

Which TWO of these animals don't have teeth?

 

WHALE BIRD LIZARD TURTLE FISH
CORRECT ANSWER
birds
turtles
EDDIE SAYS
Birds and turtles have hard beaks but they don't have teeth. Fish and lizards have small pointed teeth.
  • Question 4

Some animals have chisel-shaped incisors on their upper and lower jaws. What kind of foods do you think these would be good for eating? (Select all the options that you think are correct).

CORRECT ANSWER
tough plant roots
seeds
nuts
fruits
EDDIE SAYS
All of these are correct. Animals with teeth like this are called rodents and they are specialised for gnawing their food. They include mice, rats and squirrels. Rodents depend so much on their incisors to eat that if they break one they can't feed and will starve to death.
  • Question 5

Some animals have molars that have sharp W-shaped surfaces. What do you think these would be good for crunching up?

CORRECT ANSWER
insects
EDDIE SAYS
Animals with teeth like this are called insectivores, which means that they mainly eat insects. Hedgehogs and shrews are examples of insectivores.
