Why are cold environments considered fragile?
energy cycle
less light in cold environments
limited plant growth
frozen soil doesn't help
cold conditions prevent growth
limited water from rain
energy cycle limited
Why are cold environments considered fragile?
nutrient cycle
frozen ground/soil prevents recycling of nutrients
few nutrients in the first place
conditions are NOT suitable for decomposition
nutrient cycle limited!
