bsc1005 climate change module 3

How would you describe the impact of climate change, globally?

Greenhouse gases and their effects impact the entire planet, reaching every biome on Earth.

Select the two most important forms of insect vectors.

mosquitos ticks

How might you describe the influence of climate change on some species of mosquitoes and ticks?

Their range has expanded to include places that were previously too cold to inhabit, increasing their potential to spread disease.

Select any description of how climate change influences individuals and species.

There are more heatwaves and droughts that threaten the lives of individuals and species. The natural pace of evolution, namely extinction, is disturbed. The range of some individuals and species has expanded to include places that were once too cold to inhabit.

An ecosystem is

communities with all of their living and nonliving components.

Select the impacts of ocean acidification.

fish populations become more susceptible to disease zooplankton are reduced in numbers shellfish cannot calcify their shells

A species whose introduction to a new place has negative impacts on biodiversity, community structure, and the functioning ecosystem of the native area they invade is called a(n) ___________________ species

invasive

Select the examples of invasive species disrupting community and ecosystem function.

lionfish compete with snapper and grouper throughout the Caribbean kudzu is outcompeting native plant species

The two most important insect vectors are ticks and _________________ , which can transmit diseases like malaria and Zika virus.

mosquitoes

In general, an ecosystem includes __.

organisms and nonliving factors in their environment

A biological vector is

something that moves an infectious agent from one organism to another.

Scientists link the ability of invasive species to survive new environments to their ability to tolerate change, particularly with respect to

temperature and precipitation ranges.

Which scenarios describe the impact of climate change on global ecosystems?

Poorly managed agricultural practices like cattle farming convert grasslands into desert wastelands. Increased temperatures cause a breakdown of symbiotic relationships with algae, creating a phenomenon called coral bleaching Grasslands are converted to deserts as they are cleared, temperatures rise, and precipitation is reduced.

Choose the best description of the impact of climate change on the community level of biology.

Biological communities are linked to one another, so even minor changes within a community can have major effects.

Which of these describes how climate change is impacting the community level of biology?

Climate change has promoted the success of invasive species, which ripples out into the native communities.

Select the impacts of ocean acidification.

Fish populations are less able to reproduce Reduction in zooplankton, one source of food for fish

Shellfish are less able to calcify their shells when oceans become

acidified

Coral reefs across the planet are _______________ due to a phenomenon called coral bleaching.

dying

The term biome is used to describe similar types of

ecosystems

Climate change has the potential to increase human exposure to certain diseases, such as those carried by mosquitoes. This is because warming temperatures allow for an expanded range for these insects, which serve as vectors for diseases like ______________ , Zika virus, chikungunya, and dengue fever.

west nile

Select the examples of invasive species disrupting community and ecosystem function.

zebra mussels have driven native mussel species near to extinction rats carry disease and kill native birds gypsy moths outcompete native species

the distribution of the world's __________ follows a pattern based on average temperature and precipitation.

biome

An invasive species can be defined as

a species introduced out of its range. a species that negatively impacts biodiversity. a species that is more tolerant to change than most native species.

Which characteristic of invasive species do scientists associate with their ability to survive in new environments?

adaptability

Biome distribution follows a pattern based on

average temperature and precipitation in a region.

In biology, a _______________ is something that moves an infectious agent from one organism to another, like an insect.

vector

Climate change has the potential to increase human exposure to certain diseases, such as those carried by ticks and mosquitoes, also known as ______ diseases. This is because warming temperatures allow for an expanded range for these insects

vector-borne
