mineral ions
space
what do animals compete for
mates
territory

water
what are biotic components
living
food
predators
competition
pathogens
what are abiotic components
non living
light intensity
temp
water
ph of soil
co2 and o2
what are the types of adaptations and give examples
structural -> how animal looks -> thick fur , thin ears
behavioural -> how animal acts -> nocturnal
functional -> body functions -> sweating

what is the water cycles
evaporation
condesnsation
precipitation
passes thru rocks as aquets
transpiration
what is the carbon cycle
starts in atmosphere
entered thru photosynthesis
respiration puts back into atmosphere
what is the quadrats equation
total pop size = total area/ area sampled x nun of organisms counted in sample
