Lamprey eels survive by attaching themselves to trout.
Water temperature affects its oxygen level.
Low light intensity affects the growth of forest pine trees.

air
algae
sand
water
Which of these is a biotic factor in a river ecosystem?

the amount of soil and other particles carried by the river
the speed at which the river water flows toward the ocean
the amount of rain that flows off the land and into the river.
In many desert ecosystems, days are hot and nights are cold. Water is scarce, so animals seek water wherever possible. The spines of a cactus are actually leaves adapted to conserve water. The cactus plants have also adapted to live in thin, sandy soil. Which of the following is a biotic component of a desert ecosystem?
the thin, sandy soil
the wide temperature range
the scarcity of water
the spiny cactus leaves
Which of the following is a biotic factor in an ocean ecosystem?
the salt content of the water
the temperature of the water
the fish in the water
the oxygen in the water
Primary succession occurs in an area that has:
soil
no soil
some soil
none of these
___ are the first organisms to colonize an area and begin the process of ecological succession.
foundational organisms
introductory organisms
primary organisms

What is an example of an area that is likely to undergo primary succession?
Glaciers melt and leave exposed rock
Plants die from drought and decompose
Land is bulldozed and soil remains
What is the main difference between primary and secondary ecological succession?
Primary begins WITHOUT soil; Secondary begins WITH soil
Primary is the first state and secondary is the second stage

How does climate change impact the biodiversity of an ecosystem?
Climate change can lead to habitat loss, changes in temperature and precipitation patterns, and increased frequency of extreme weather events, all of which can directly impact the biodiversity of an ecosystem.
Climate change only affects human populations
Biodiversity increases with climate change
Climate change has no impact on biodiversity
How does climate change affect the migration patterns of species?
Climate change has no impact on the migration patterns of species
Migration patterns of species are not influenced by temperature and precipitation changes
Climate change can alter the temperature and precipitation patterns, which can directly impact the habitats and food sources of species, leading to changes in their migration patterns.
Species are not affected by climate change
What are the consequences of climate change on species distribution?
No impact on species distribution
Shifts in species distribution
Decrease in species diversity
Increase in species population
In what ways does climate change influence ecosystem services?
By reducing the impact of invasive species on ecosystem services
By altering temperature and precipitation patterns, leading to changes in species distribution, habitat loss, and disruption of ecological processes.
By promoting the growth of diverse and healthy ecosystems
By increasing the availability of resources for ecosystem services
Describe the impact of climate change on the provision of ecosystem services.
Climate change has no impact on ecosystem services
Climate change can alter the distribution and abundance of species, disrupt ecological processes, and reduce the ability of ecosystems to provide essential services.
Ecosystem services will improve as a result of climate change
Climate change only affects a few species and has no overall impact on ecosystems
The main human activity that releases greenhouse gases is
using public transportation and there by reduce the affects of greenhouse gases.
burning fossil fuels
texting on cellphones
eating meat
