Feeding Adaptations
Learning Objectives
•
•
•
To know how some animals are adapted to feeding.
To describe at least two general adaptations of predators and prey.
To explain the differences between herbivore and carnivore
adaptations for feeding.
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Predators
PREDATORS are animals which hunt and feed on
other animals.
The animals they hunt are their PREY. Predators
have adaptations that allow them to catch to catch
their prey.
Animals which eat other animals are called
CARNIVORES. They use their senses to find their
prey.

Sensitive for

prey.
Fur to

warm
Sharp teeth
Claws for
digging for
prey
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Prey
PREY is the name we give to animals which have
other animals above them in the food chain, and are
eaten by carnivores.
Many prey are HERBIVORES, although some
carnivores are prey to larger carnivores.
Prey animals need to use their senses to detect
predators, and their adaptations to hide or escape
from them.
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Fallow Deer
Antlers for
defence
Tough tongue
for
stripping leaves
from shrubs
Mottled fur
for
camouflage
Eyes on side
of the head,
for greater
peripheral
vision
Long legs
for escaping
predators
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Hare
Brown fur
for warmth
and
camouflage
Long legs
to move
quickly
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Large ears
for hearing
predators
Eyes on
the side of
the head,
for good
peripheral
vision
Herbivore Adaptations
HERBIVORES are animals which feed only on plants.
Herbivores use their senses to find food – sight, smell
and touch.
Many herbivores also have special adaptations for
feeding - for example, birds beaks are different
shapes and sizes depending on their food source.
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Bird Beaks - Adaptations
Flat beak
Thick, strong beak
Long, pointed beak
For sifting
For crushing seeds
For searching in
sand for shellfish
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Investigating Beak Shape
You are going to see how beak size effects the type of seed a bird can eat.
You have two ‘birds’ :
• Pointed beak
• Flat beak
PREDICTION
Do you think the pointed beak or the flat beak will be better for collecting seeds?
Why?
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Method
1. Take one type of beak.
2. One person is going to be the bird.
3. In one minute, they must collect as many seeds as they can and put them into the
beaker.
4. Organise all the seeds into groups of same seed type, and record the number of
seeds in your table.
5. Repeat your experiment using the other beak type.
Did your results match your hypothesis?
KEY WORDS: Carnivore, Herbivore, Omnivore, Predator, Prey, Adaptation
Results
Type of seed
Pointed beak
Pumpkin seed
Cress seed
Sunflower seed

Flat beak
Design an Alien
You are going to design an alien.
Your design MUST:
• Give an explanation of the environment where it is found
• Identify how the creature is adapted to its environment / to feed
Your design SHOULD:
• Explain how its adaptations help it to survive / to feed
