primary
secondary
tertiary
quadanary
Succession type?
primary succession
secondary succession
tertiary succession
variable succession
What type of growth does invasive species show and why?
Logistic growth because there is large competition with native species
Exponential growth because there is no natural predators and competition in the new environment
Predator/ Prey because the invasive species begins to prey on native species
Exponential growth because the native species outcompete with the invasive ones and cause a limit on their population growth
Which of the following limiting factors is NOT a Density-dependent factor?
Food
A Forest Fire
Water
Space to live
Which of the labeled processes in the picture of the Nitrogen Cycle is the process of turning Nitrogen from the atmosphere into usable nitrogen for plants to use to grow?
Ammonification
Nitrogen Fixation
Denitrification
Assimilation
What organisms recycle Carbon back into the atmosphere through the process of respiration?
Animals
Plants
Boats and Cars
Plants and Animals
Which of the following biomes has the highest precipitation?
desert
rainforest
savanna
temperate forest
This biome receives a lot of rainfall during some seasons and is dry during others. There are fires that occur here and lots of grazing animals.
temperate forest
savanna
taiga
tundra
This biome has bears, wolves and moose and animals that migrate during the long winters.
taiga
tropical rainforest
desert
savanna
this biome has cacti and other plants with long roots to survive the dry climate and sharp spines to protect it from predators
desert
taiga
temperate forest
tropical rainforest
this biome has very little rain and is very cold. a layer of permafrost covers the soil. there are no trees found here - mostly mosses and lichens.
temperate forest
desert
taiga
tundra
in this biome, you would find trees with leaves that change color and fall of when temperatures get too cold (deciduous trees)
taiga
desert
tundra
temperate forest
this is known as a relationship in which one organism benefits, while the other is unaffected
parasitism
mutualism
predation
commensalism
a clownfish uses a sea anemone as a safe place to live. while the clownfish is benefitting from the sea anemone for protection, it is also luring in food for the anemone to eat. what type of relationship is this?
mutualism
commensalism
predation
parasitism
a mosquito feeds off of the blood of different organisms. this usually causes discomfort to the organism and sometimes even death by disease. this is an example of....
commensalism
parasitism
competition
mutualism
this type of relationship occurs when two organisms are "fighting" over a common resource (ex. mates, food, water, shelter)
competition
predation
commensalism
mutualism

What is the order that plants grow to repopulate the area in primary succession, such as a glacier receding or a volcano covering land with lava?
Lichens → Shrubs → Grasses → Trees
Lichens → tree → shrubs→Grasses
Grasses → Lichens → Shrubs → Trees
Lichens → Grasses → Shrubs → Trees
How much energy is lost as heat between the trophic level of the producers and the primary consumers?
10%
50%
70%
90%
Which of these are examples of combustion?
Burning fossil fuels and trees
Decomposition
Diffusion
Cellular respiration
Why is nitrogen limited when the atmosphere is 78% nitrogen?
It isn't limited
Not many organisms can fix nitrogen, which means turn it into a useful form
Nitrogen is so light that it floats above the rest of the gases in the atmosphere and most organisms can reach it

land breezes
mountain breezes
global winds
land breezes
Which statement correctly defines wind?

The movement of air to a colder area in the atmosphere.
The movement of air from areas of high pressure to areas of low pressure.
The movement of air pushed around and bouncing off Earth's surface.
What is the initial source for global winds and convection in the atmosphere?
heat from the Earth's core
the rotation of the Earth
Moon's gravity
unequal heating of the Earth by the sun
