Quiz Answers

1. What do we call an organism that can make it’s own food using sunlight, water and carbon dioxide?

Producer2. What is the process that plants use to make their own

food called? Photosynthesis3. Organisms that eat other living things for food are

called? Consumers4. Decomposers are important because they recycle

something back in to the soil for plants to grow. What is it that they recycle? Nutrients

5. Consumers can be split in to three types. What are the three types?

Herbivores, Carnivores, Omnivores

Adaptations

All organisms (living things) carry out the seven life functions MRS GREN

The way each animal and plant does these things is different depending on where they live – their habitat

For example: MovementA snake doesn’t move in the same way as a

cheetah

ReproductionA tree doesn’t reproduce in the same

way as a fish

NutritionA kiwi gets it’s food differently to an eagle

These features that help an organism survive and reproduce are called adaptations

What is an adaptation?Adaptations are features that an organism

(living thing) has that help it to survive and reproduce in the environment that it lives in.

There are three types of adaptation:1. Structural adaptation – a part of an

organism that helps it carry out a life function

2. Physiological adaptation – a process inside an organism that helps it to survive

3. Behavioural adaptation – some activity that an animal does to help it survive

Adaptations

Adaptations are features that an organism (living thing) has that help it to survive and reproduce in the environment that it lives in.

There are three types of adaptation:1. Structural adaptation – a part of an organism

that helps it carry out a life function2. Physiological adaptation – a chemical or

process inside an organism that helps it to survive3. Behavioural adaptation – some activity that an

animal does to help it survive

Structural Adaptations

A structural adaptation involves part of an organisms body e.g. Dogs and sharks have sharp teeth for eating other animals (cutting, ripping, shredding)

Physiological Adaptations A physiological adaptation involves

processes occurring inside organisms e.g. Snakes and spiders create venom that they can use to help them catch prey to eat.

Physiological AdaptationsGum tree leaves produce toxins

(poisons) that stop grazing animals like possums from eating them

Behavioural AdaptationsAn activity that an organism (living

thing) does to help it survive e.g. Fish school up so that they are less likely to get eaten.

Behavioural AdaptationsAnimals such as sheep and antelope live

in flocks or herds so that they are less likely to get eaten

• Prairie dog’s keep a lookout at all times to watch for predators

Behavioural Adaptations

Kiwi feed at night (nocturnal) because there are more insects and worms around for them to eat

Cats hunt at night because it is easier for them to catch their prey

Structural vs Behavioural AdaptationsWhat type of adaptations are described in each of

the following statements? Structural, Behavioural or Both

E.g. Cats hunt at night – Behavioural1.Small fish living in a school2.Birds migrating north in winter3.Ducks have webbed feet4.Cactus has needles for protection5.Sharp claws on a bear6.Long roots on a tree in a dessert that go deep in to

the soil

If you are finished explain how the adaptation helps the organism to survive in it’s habitat

Structural vs Behavioural Adaptations

1. Small fish living in a school - Behavioural

2. Birds migrating north in winter - Behavioural

3. Ducks have webbed feet - Structural4. Cactus has needles for protection -

Structural5. Sharp claws on a bear - Structural6. Long roots on a tree in a dessert that

go deep in to the soil - Structural

Adaptations for Photosynthesis

Leaves have external and internal features which help them carry out photosynthesis. These features are called adaptations

Flat and wide to capture maximum sunlightThin to allow maximum light penetrationVeins transport water to and sugars from the

leavesGreen colour is from the chlorophyllPores in the leaf let carbon dioxide and oxygen to

move in and out of the leafWaxy surface limits water loss

AdaptationsAdaptations affect the survival of

the organism

How it takes its food and oxygenHow it produces offspring

Organisms that survive pass along their traits to the next generation (natural selection)

Other organisms that do not have traits suitable to the environment may not survive or reproduce
