What do organisms require to survive?
A supply of materials from surroundings and other organisms
What 4 factors do plants compete for?
Nutrients in the soil
What 3 factors do animals compete for?
What's the name to organisms that live in radical conditions
What can extremophiles be tolerant to?
High levels of salt, temperature or pressure
Name adaptations for an animal in dry conditions - Camel
Large surface area to volume ratio: increases heat loss
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
Name adaptations for an animal in artic conditions - Polar bear
Small surface area to volume ratio: to reduce heat loss
Large flat feet: for grip and lowers pressure
Greasy fur: sheds water reducing heat loss
Thick fur and lots of fat: increase insulation
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
What does intraspecific competition mean?
Competition within the same species
What does interspecific competition mean?
Competition between different species
Name factors that predators have
Eyes at the front: they need depth to judge distance of prey
Name factors that prey have
Eyes at the side of the head: to see a wider view of predators

Name a biotic factor
Name an abiotic factor
