Regions & Climate
This region is located between 0° and 23.5° N/S.
What is the Tropical Region?
This type of growth never reaches carrying capacity.
What is exponential growth?
This is the predictable change in community structure over time.
What is ecological succession?
A bird builds a nest in a tree. The bird benefits, while the tree is unaffected.
What is commensalism?
Melting ice caps can weaken this by reducing the amount of energy given to it.
What is the Polar Vortex?
This region is located between 23.5° and 66.6° N/S.
What is the Temperate Region?
This limiting factor has no correlation to population size.
What is a density-independent limiting factor?
This type of succession begins with moss and lichen.
What is primary succession?
A lion and cheetah hunt gazelles in the same area. Their relationship is this because they are using the same resource.
What is competition?
The sagging of jet streams can allow this type of air to enter the Temperate Region.
What is cold Polar air?
This region is located between 66.6° and 90° N/S.
What is the Polar Region?
These organisms are generally large-bodied, have few offspring, and invest heavily in their young.
What are K-selected organisms?
This stage of succession includes grasses, woody shrubs, and softwood trees and supports the most species diversity according to your practice exam.
What is the grasses, woody shrubs, and softwood trees stage?
A giraffe and acacia tree both adapt over time—the tree develops spiky leaves while the giraffe develops a rough, sticky tongue.
What is coevolution?
Changes in where rain falls can affect this important human activity.
What is agriculture?
In the Temperate Region, this side of a mountain receives the rain shadow.
What is the East side?
This type of survivorship curve describes organisms like sea turtles that have a limited number of predators once they become large.
What is a Type III survivorship curve?
A disturbance can be considered beneficial when it helps maintain this within an ecosystem.
What is high diversity?
This occurs when a new species is introduced to an area and contributes to another species being unable to use the same resources.
What is competitive exclusion?
Overharvesting fish faster than they can reproduce means humans are not practicing this.
What is sustainable yielding?
During this Tropical Region season, land becomes warmer than the ocean, releasing heat into the air and causing rainy conditions and monsoons.
What is Tropical Region summer?
A population has 700 spiders. During the year, 200 die from bug spray, 80 are smushed, and 140 babies survive. What is the PCG?
What is 0.2?
A forest fire, tornado, flood, or logging event can create a disturbance. The key question is whether the disturbance helps maintain diversity rather than completely destroying this.
What is the ecosystem?
Herbivory is different from predation because in herbivory, this usually does not happen to the plant.
What is death?
