1

What do organisms require to survive?

A supply of materials from surroundings and other organisms

2

What 4 factors do plants compete for?

Space
Light
Water
Nutrients in the soil

3

What 3 factors do animals compete for?

Mate
Food
Territory

4

What's the name to organisms that live in radical conditions

Extremophiles

5

What can extremophiles be tolerant to?

High levels of salt, temperature or pressure

6

Name adaptations for an animal in dry conditions - Camel

Large surface area to volume ratio: increases heat loss
Camouflage
Fat store: in a hump not around it's body to reduce insulation
Little water loss in the urine
Long legs: to reach vegetation
3 eyelids and long eyelashes to keep the sand out
Hooves to help not sink into the sand

7

Name adaptations for an animal in artic conditions - Polar bear

Small surface area to volume ratio: to reduce heat loss
Camouflage
Large flat feet: for grip and lowers pressure
Greasy fur: sheds water reducing heat loss
Thick fur and lots of fat: increase insulation

8

Name adaptations for a plant in dry conditions - Cactus

No leaves: small surface area so it does get even more sunlight
Spikes: minimise water loss and protect itself
Large roots: to find water and to anchor it
Chlorophyll: to photosynthesise
Water storage tissues: to use the water as a spine

9

What does intraspecific competition mean?

Competition within the same species

10

What does interspecific competition mean?

Competition between different species

11

Name factors that predators have

Eyes at the front: they need depth to judge distance of prey
Camouflage
Sharp teeth
Claws

12

Name factors that prey have

Eyes at the side of the head: to see a wider view of predators
Large ears
Strong muscles
Camouflage

13

What is the name for a non-living factor?

Abiotic

14

What is the name for a living factor?

Biotic

15

Name a biotic factor

Food availability

16

Name an abiotic factor

Rainfall
Oxygen levels
Temperature

17

What living organism can be used as air pollution indicators

18

What do lichen detect

Concentration of sulfur dioxide

19

What living organism can be used as water pollution indicators
