The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Convention on Biological Diversity are examples of

international treaties to protect biodiversity.

organizations that promote poaching.

international organisation on climate change.

laws to increase the number of species

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

The introduction of Alien species affects biodiversity negatively if the alien species;

has a faster growth rate than native species

outcompetes the native species for resources

carries a new pathogen into the native species habitat

What is species diversity?

the variety of different organisms in an environment

the number of individuals in a population

the number of habitats on a continent

how much food is available in a habitat

Which of these describes genetic diversity?

variety in genotypes across a population

number of different species in an ecosystem

the number of species on the planet

number of populations in an ecosystem

The theory of evolution says that living things ___________.

stay the same throughout history

Why is biodiversity so important?

Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well

Because it’s better to have only one variation of each species.

Because it better to only have a few species on Earth.

Honestly, I have no idea what biodiversity is!

What does biodiversity mean?

The different amount of species in an area

a characteristic that helps and organism survive in its environment.

a theory of how organisms change.

the genes in an organism that determine how an organism is going to look.

Ecosystem biodiversity is best described as . . .

The variety of different ecosystems there are in the biosphere

The different type of biomes there are

The different types of abiotic and biotic factors as well as climate within environments

Having more diversity allows organisms and environments to...

Evolve and Adapt at a slower rate

What actions decrease biodiversity?

Monocrop Farming / Mining / Overfishing / Over hunting

What happens when species become extinct?

the whole species does not exist

the adults are dead but some eggs still have not hatched

the species do not exist in some parts of the world

A charismatic, often cute and cuddly flagship species may be used to promote human connection, but what are the disadvantages of such species?

Humans may be in conflict with them eg Tigers eat people

They may become extinct and so the conservation work would stop

They take priority even if they are not important to the ecosystem

They can be made into cuddly toys for marketing

They become popular within the public

Which of these factors increase speciation because of plate tectonics?

New island formation which is an isolated land mass

Fold mountains forming which divide populations from each other

Land bridges allowing populations to move between land masses

Change in climate as the continent moves to different longitudes

Increased natural selection from the release of volcanic gases

Which of these are NOT an INDIRECT reason to conserve biodiversity?

Species which we eat may be wiped out by disease so we may need older varieties' genes in the future

Species have the fundamental biorights to exist

The species or ecosystem provides services we need

Species may have genes we can use in genetic engineering
