Structural, functional, and behavioral adaptations help organisms survive in different environments. Structural adaptations involve changes to organs and tissues that allow organisms to perform specific functions. For example, whales have paddle-like limbs adapted for swimming. Functional adaptations involve changes in activity, like birds migrating seasonally. Behavioral adaptations involve changes to locomotion, such as mammals modifying their limbs for walking, flying, swimming, climbing or diving. Adaptations occur through natural selection and help organisms fulfill needs like finding food and mates.

Adaptation

5. • It is an adaptation of some organs and tissues to do a specific
function.
• Ex:
• Secreting sweat in humans in case of high temperature.
• Secreting poison in snakes.

6. • It is an adaptation in the activity of some animals in different
times of the daylight.
• Ex:
• Birds migration at certain times of the year
• Activity of birds during the daylight and bats at night

8. • mammals’ limbs were modified in many shapes and forms to suit
the required ways of movement
• Such As:
• Walking, Flying, Swimming, Climbing And Diving.

9. The type of
adaptation
The aim of
modification
The modification in its
limbs
The mammals
Structural
adaptation
To perform the
function of swimming
and diving in water.
The two forelimbs of
whales, dolphins and sea
lion are modified to become
paddles (fin-like structure)
Whale
structural
adaptation
To perform the
function of flying.
The two forelimbs are
modified into two wing-like
structures
Bat
Structural
adaptation
To perform the
function of running on
the rocky soil.
Its limbs are modified
To end with a strong hoof.
Horse
Structural
adaptation
To enable it to climb
trees and catch things.
The bones of the forelimbs
and fingers are elongated.
Monkey and gorilla

10. 1. Modification in birds' beaks to suit the kind of food.
2. Modification in birds' legs to suit the way of movement.

11. The type of
adaptation
The modification of its beak and legThe bird
Structural
adaptation
* Beaks Strong and sharp crooked beaks to tear the
prey’s flesh.
* Legs Four fingers ending with strong and sharp
claws, three anterior (front) fingers and one posterior
(back) bendable to firm pouncing the prey.
Birds which feed on meat
(Predatory birds).(e.g. hawks and
vultures)
Structural
adaptation
* Beaks: Long thin beaks to pick up worms and snails.
* Legs : Long thin legs ending in thin fingers to walk
in the existence of water.
Birds that feed on shallow water
worms and snails. (e.g. Heron and
hoopoe)
Structural
adaptation
* Beaks Wide indented beaks in the two sides to help
them filter the food from water.
* Legs: Palm legs to help in swimming.
Birds which feed on mosses and
fish (Water birds) e.g. ducks and
geese.

12. • Insectivorous plants:
• They are self-feeding (autotrophic) green plants because they can perform
photosynthesis process so, they can make carbohydrates.
• They can’t make proteins because they can’t absorb the nitrogenous substances
needed to make proteins from the soil.
• Some parts of these plants are adapted and modified to pounce (capture) and
digest the insects, then absorb the nitrogenous substance that their bodies need.
