Survival!!!!

What’s the point?•I can tell that living things can only survive in environments that meet their needs.•I can describe the basic needs of living things.•I can explain that ecosystems can change and only animals that adapt survive.

What do all organisms need to survive?

(get rid of waste)

Have you ever wondered how animals are able to survive in the wild and meet their

needs?

Animals have certain adaptations- special characteristics that help

them to survive.

Think about the way you dress in the winter.

You don’t wear your shorts and bathing suit when it’s snowing outside!

You wear warm clothes, and maybe even a hat and mittens to protect

yourself from the weather.

And what if you are having a snowball fight?

You probably run away from the person throwing at you,

and maybe even try to sneak up on that person and

throw some snowballs!

The way you dress in the winter, as well as the way that you run and hide from

someone throwing snow at you are kinds of …

Adaptations.

Physical adaptations

are body structures that allow an animal to find and consume food, defend itself,

and to reproduce its species.

Physical adaptations help an animal survive in its environment.

Hey! I’m a walking

stick. I look just like a

stick you’d find on the

ground.

Physical adaptation

Camouflage (use of color in a surrounding)

The chameleon can change its color to match its surroundings. Can you do that?

Mimicry (looking or sounding like another living

organism)

The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart?

Poisonous

Not poisonous

Physical adaptation

I’m the Monarch!

I’m the Viceroy!

Chemical defenses (like venom, ink, sprays)

Physical adaptation

Body coverings & parts (claws, beaks, feet, armor plates, skulls, teeth)

Physical adaptations

The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick

things up.

1. Which physical adaptation do you think is most important for survival? (camouflage, mimicry, body structures, or chemical defenses)

2. How do these adaptations help organisms meet their basic needs?

3. Questions???

Now let’s learn about

Behavioral Adaptations…

Behavioral Adaptations allow animals to respond to

life needs.

Each organism has unique methods of adapting to its environment by means of

different actions.

Behavioral Adaptations are animals’ actions.

Remember that Physical Adaptations are body

structures.

Raising young

Finding shelter

Methods of gathering & storing food

Defending oneself

Hibernating

Migrating

1. Which type of behavioral adaptation do you think is most important for survival? (method of gathering food, defense, hibernation, migration, raising young, or finding shelter)

2. How do these help the organisms survive?3. Questions???

Animal Adaptations Review

There are 2 ways to describe adaptations:

Physical and Behavioral

Behavioral adaptations are animals’ actions.

Some examples of behavioral adaptations are:

Finding Shelter

Hibernating

Defense

Migrating

Physical Adaptations are body structures.

Some examples of physical adaptations are:

Camouflage

Mimicry

Body Coverings & Parts

Chemical defenses

Examples of Adaptations

How does this aye-aye adapt?

What need(s) does it meet?

How does this Venus Fly Trap adapt?*plants have adaptations too!

What need(s) does it meet?

Questions?????

Designer Organism Steps:1) Choose an ecosystem.2) Design a new organism with at least 3

adaptations that will help it survive in that ecosystem.

3) Create the organism and name it.4) Record the information about your organism

on the Adaptations Information Sheet and write a descriptive paragraph about your organism.

1. Adaptations 2. Competition 3. Symbiosis

Contest among populations Organisms compete for:

› Food› Water› Mates› Shelter› Space

Adaptations help organisms compete “Survival of the Fittest”

Relationship between organisms Types:

› 1. Mutualism (Both organisms benefit) Ex-ants and caterpillarsYouTube - Ant Caterpillar Mutualism

› 2. Commensalism (One organism benefits) Ex-sharks and remorasYouTube - Nurse shark & Remora

› 3. Parasitism (One organism benefits, the other is harmed) Ex-bacteria, viruses
