During natural selection, the organisms with the best adaptations..
Are better adapted to survive
Reproduce
Pass on their genes
All of the above
Which statement is true comparing natural selection and artificial selection?
In natural selection, traits benefit humans and in artificial selection, the traits benefit the species
In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
In natural and artificial selection, the process takes hundreds of years to occur
In natural and artificial selection, nature determines what traits will be passed down to offspring.
Which of the following is NOT an example of natural selection?
People selectively breeding hamsters.
Insect populations developing resistance to certain pesticides.
Bacteria becoming resistant to antibiotics.
Male birds of certain species developing colorful feathers to attract female mates.
What is the process in which populations CHANGE gradually over time?
evolution
species
variation
competition
What do you call a characteristic that allows an organism to survive in an environment?
variation
adaptation
selection
overproduction
According to the theory of natural selection, what will most likely happen to a species that lacks the variations necessary to adapt to a changing environment?
Mutate
Fossilize
Become extinct
Become dormant
What must a species be able to do in order to survive?
Consume a wide variety of food
Maintain a constant body temperature
Destroy competing species
Reproduce successfully
A form of evolution where two species having a close ecological relationship evolve together such that one species adapts to changes in the other, thereby affecting each other's evolution.
divergent evolution
convergent evolution
coevolution
Hummingbirds have a beak just the right length to reach the nectar in the long cardinal flower. The cardinal flower’s pollen tube is just the right length for the hummingbird to pick up pollen as it feeds.
divergent evolution
convergent evolution
coevolution
Fungi obtain energy
Directly from the sun
From inorganic (unnatural) materials in their environment
By absorbing organic (natural) materials
From nuclear fusion

nitrification
denitrification
ammonification
assimilation
Breaking News! A new island has formed off of Hawaii! What must occur for it to become an ecosystem?

Tropical Rainforests are located:
Near the South Pole
Near the Equator
Near the North Pole
Above the Tropic of Cancer
How many layers does a tropical rainforest have?
2
1
4
3
The biggest threat to rainforests comes from:
Disease
Parasites
Humans
Predators
Taiga
Tundra
Desert
Temperate Rainforest
Which layer in the Tropical Rain Forests absorbs about 95% of sunlight from reaching the bottom?
emergent layer
canopy
understory
non of the options
True or False: More light reaches deciduous forest floors than the rain forests floors, which allows more plants to grow there.
True
False
All the following are characteristics of Temperate rain forests except which one?
The biome has cool humid weather and abundant rainfall.
The biome has lots of mosses, ferns, and lichens.
The soil is permanently frozen throughout the year.
The biome is found in places like Washington state
Some adaptations demonstrated by plants in tropical rain forests include:
a. trees with above ground roots called buttresses, which increase stability.
b. plants known as epiphytes use other plants for support and are in trees by the canopy
c. plants with tiny leaves located in the understory capture the most sunlight
d. Both A and B are correct
The main threat that Tropical Rain Forests have is what?
deforestation, excessive cutting of trees
a decrease in the average temperature at the equator
a decrease in rainfall at the equator
thinning of the soil
. Before winter begins in temperate deciduous biomes, many organisms migrate to the warmer environments in the southern hemisphere. An example of an animal from this biome that migrates south are_____.
Mammals
Reptiles
Birds
All the options are true
Which Forest biome is found near sub-arctic regions?
tropical rain forest
temperate deciduous forest
temperate rain forest
taiga
The taiga biome doesn’t receive high amounts of precipitation compared to the other forest biomes. Thus, taiga plants are adapted to conserve water. What is an example of a plant adaptation seen in a Taiga?
Needle-like leave shape of conifers to conserve water
wax coating on needle-like leaves to prevent water loss
Conifer needles cause soil to become acidic to prevent other plants from growing nearby that would take their water
All the options are examples of plant adaptions
