Which of the following situations is MOST likely to result in the formation of a new species?
A population of squirrels lives in a stable forest habitat.
A population of birds lives in a stable forest habitat.
A population of squirrels lives in an area where a large river forms and cuts through the middle of the forest.
A population of birds lives in an area where a large river forms and cuts through the middle of the forest.
From the graph above, what can you conclude about speciation and extinction rates in different parts of the world?
The speciation and extinction rates are both higher in tropical areas than they are in temperate areas.
The speciation and extinction rates are both higher in temperate areas than they are in tropical areas.
The speciation rates are higher in tropical areas than they are in temperate areas, while the extinction rates are higher in temperate areas than they are in tropical areas.
The speciation rates are higher in temperate areas than they are in tropical areas, while the extinction rates are higher in tropical areas than they are in temperate areas.
Which of the following factors would likely contribute to an increase in the number of species in an ecosystem? Select All that apply.
Faster formation of species from natural selection.
Stability or instability within the ecosystem
A reduction in the extinction rate.
New environmental factors with which organisms must cope.
The environment is constantly changing due to weather patterns, geological events, and human activity.
If a species cannot adjust to these changes in order to successfully reproduce, then it is MOST likely that the species will
Develop new adaptations to accommodate for the environmental changes
Become extinct.
Form a new symbiotic relationship with another species
Migrate to a new environment that will meet its needs.
The place where an organism lives and that provides the things the organism needs is called its
habitat.
population.
species.
community.
The struggle between organisms to survive in a habitat with limited resources is called
competition.
predation.
symbiosis.
parasitism.
When a jellyfish paralyzes a tiny fish with its poisonous tentacles, the fish is the
predator.
prey.
host.
parasite.

Using the climate change evidence table, what change did snails experience?
more common to be lighter in color
migrate earlier in the season
netherlands
auke creek, alaska
Using the climate change evidence table, what change did salmon experience?
more common to be lighter in color
migrate earlier in the season
netherlands
auke creek, alaska
Using the climate change evidence table, explain how this change would help the snails
migrating earlier in the season means that they will find warmer waters to reproduced in
migrating earlier in the season will allow them to be able to reproduce in the colder waters they are used to
being lighter in color means that the snails will absorb less heat and stay warmer in the cold weather
being lighter in color means that the snails will absorb less heat and stay cooler in the hot weather

Claim: all species are going extinct. Does the evidence support or refute the claim?
support, the table shows all species going extinct
refute, the table shows adaptations of species to climate change
refute, the table shows speciation of species to climate change
support, the table shows most species going extinct
