Adaptations
Characteristics which increase an organism's chance of survival in the environment in which it lives
1 of 10
How is the Fennec Fox adapted?
It has large ears to increase its surface area to volume ratio to help it lose heat
2 of 10
How is a Camel adapted?
Are able to tolerate large changes in temperature, keep all their fat in a hump on their back to help them lose heat from the rest of their body, Light brown colour for camouflage
3 of 10
How is a Cactus adapted?
It has spines instead of leaves to reduce surface area, a thick stem for water storage, shallow extensive roots to maximise water collection
4 of 10
How is a Polar Bear adapted?
A round shape for a small surface area to volume ratio, a thick layer of blubber and thick white fur to camouflage and keep warm, black skin to absorb heat
5 of 10
Extremophiles
Are adapted to live in extreme conditions such a s a volcano
6 of 10
Environmental changes affected by Living Factors include:
A change in the occurrence of infectious diseases, a change in the number of predators, a change in the number of prey, a change in the number of competitors
7 of 10
Environmental changes affected by Non-Living Factors include:
A change in the average temperature, a change in average rainfall, a change in the level of air or water pollution
8 of 10
How to monitor Air Pollution:
Look at particular types of lichen- if the air is clean, there are lots of lichen
9 of 10
How to monitor Water Pollution:
Some invertebrate animals(mayfly larvae)- if there is mayfly larvae then the water is clean
