Adaptations

Question 1

What is evolution?

Answer 1

A process where a species changes over time in order to become better adapted to their environment

Question 2

What makes a successful species?

Answer 2

Members of the same species must live long enough to reproduce

Question 3

What happen to species that are less well adapted?

Answer 3

Decrease in members and may become extinct

Question 4

What are adaptations?

Answer 4

Any feature that makes an individual well suited to their environment, helping them to survive

Question 5

What are the 3 types of adaptations?

Answer 5

Behavioural, structural and physiological

Question 6

What is structural adaptation?

Answer 6

How the body of an organism is suited to its environment

Question 7

What do structural adaptations affect?

Answer 7

The way an organism looks

Question 8

Give an example of a structural adaptation PB

Answer 8

Small features to reduce heat loss
Black skin to absorb heat
White fur to camouflage
Layer of fat to insulate and keep warm
Thick, padded paws to walk on ice

Question 9

Give an example of structural adaptation G

Answer 9

Camouflaged coat to help hide long legs
Long neck to reach leaves high up on trees that aren’t grazed by other herbivores

Question 10

Give an example of structural adaptation T

Answer 10

Stripes to camouflage in grass, helps survival chances as they can stalk prey unseen
Sharp/long teeth + claws to capture and eat large prey

Question 11

Give an example of structural adaptation, cactus

Answer 11

Spines (well adapted leaves) to protect from grazers and to reduce water loss
Stems made of succulent tissue that expand + store large volumes of water that allows it to survive periods of drought
Wide + shallow roots to collect surface water

Question 12

What is a physiological adaptation?

Answer 12

Adaptation which involves internal processes within the plant or animal

Question 13

Give an example of a physiological adaptation Pineapple

Answer 13

Close pores on leaves surface during the day to reduce water loss and prevents Co2 needed for photosynthesis from entering the leaves
Collect Co2 at night & store it until needed during the day

Question 14

Give an example of a physiological adaptive peng

Answer 14

Capable of storing large quantities of O2, allows peng to hold breath for up to 22m allowing it to exploit food sources that other species can’t reach allowing peng to survive in areas with high comp for food

Question 15

What is a behavioural adaptation?

Answer 15

Either built in or learned and will increase the survival chances. Affects the way an animal behaves
