Final Flashcards
Name two organisms that use camouflage
Walking sticks and dead leaf mantis
Environmental factors may cause multiple phenotypes from a single genotype
Phenotypic Plasticity
This biome has a climate where it had long, cold winter and short cool growing season. Dominant plant life form here is various low growing plants. Too short of a growing season for trees.
Tundra
This biome has long cold winter but a short but mild growing season. Dominant life form is needle leaf evergreen tree.
Boreal forest
This kind of tree had a set of leaves that doesn’t have to make new sets of leaves and there drought resistant which helps it survive in the winter.
Evergreen with needle like leaves
This biome has cold winter but the growing season is long and warm. Dominant plant form is broad leaf deciduous tree. Long enough growing season to where no adaptive Advantage to having evergreens. Trees lose leave minimize water loss.
Temperate Deciduous Forest
Dominant plant form is grass. Rainfall is insufficient for trees. Grass is dominant because of frequent fires in the past and over grazing animals.
Grasslands (Prairie)
No dominant plant form due to lack of water. Plant forms have small drought resistant leaves or none at all. They have a deep root system and shallow spreading roots to soak up lots of water. Lots of ectotherms.
Desert.
This biome has abundant rainfall year around and is warm year around. Dominant plant form is the broad leaf evergreen tree.
Tropical rain forest
Lag of several decades between declining birth rate and the slowing of population growth.
Demographic momentum
Countries with the most developed economies and most educated people generally have the lowest birth rates.
Demographic Transition
Role within a community
Niche
Living in relationship
Symbiosis
An organism feeds upon host whole living on it
Parasitism
Both species benefit
Mutualism
