an organism is only found in a certain area
A group of organisms in danger of extinction
When an organism is no longer found in a certain area
2
Biological diversity is mostly threatened by
erosion
DDT
educating the public
habitat destruction
3
An organism that is originally from a different place, but thrives in another is considered
extirpated
endemic
extinct
invasive
4

respiration
photosynthesis
combustion
decomposition
5
What happened a little over 200 years ago that greatly impacted the amount of carbon in the air?
industrial revolution
World War II
death of the dinosaurs
United States of America was founded
6
What is changing the Earth's environment most drastically?
sustainable development
Human Activity
erosion
old-growth forests
7
Why would the zooplankton and small fish not be affected like the fish-eating birds?
DDT is good at killing birds, not fish and zooplankton
lower concentration of DDT
DDT doesn't affect fish and zooplankton at all
DDT is designed to affect birds and nothing else
8
What might happen to the birds in this situation?
they will die in flight and fall from the sky
eggs will be laid with brittle shells
they will transfer their energy to the ground
they will run out of food to eat
9

photosynthesis
combustion
respiration
atmospheric carbon dioxide
10

protection of biodiversity
preservation of habitats and wildlife
keep humans happy
wise management of natural resources
11
On what part of the carbon cycle is the star?
feeding
photosynthesis
combustion
respiration
12
List 3 ways carbon is stored in the biosphere?
underground as fossil fuel and calcium carbonate rock
in ocean as dissolved carbon dioxide
in atmosphere as carbon dioxide
in lava pouring out of a volcano
13
On what part of the carbon cycle is the star?
decomposition
photosynthesis
feeding
respiration
14
On what part of the carbon cycle is the star?
combustion
respiration
photosynthesis
feeding
15
What has caused species to become extinct more rapidly recently?
The activities of people
acid rain
invasive species
animals not being tough enough to survive climate change
16
What are 3 threats to biodiversity?
biological magnification of toxic compounds
invasive species
habitat fragmentation
sustainable development
17
What process is being shown?
trophic levels
DDTing
food web
biological magnificiation
18
When an ecosystem is disrupted, what might happen?
only plants will be affected
erosion
DDT with biomagnify
thousands of species existence is threatened
19
Do most microplastics start out tiny? Where (on earth) do most microplastics come from?
No; the ocean
Yes; Inland
No; Inland
Yes; the ocean
20

the number of different species in the biosphere
the number of organisms in an area
organisms that cannot be found anywhere on earth.
21
Define biodiversity.
how many humans in an area
the number of different species in the biosphere
a group of organisms in danger of extinction.
the number of organisms in an area
22
T or F: Biological systems don't use up matter, they transform it.
False
True
23
On what part of the carbon cycle is the star?
respiration
photosynthesis
atmospheric carbon dioxide
combustion
24
What were 2 properties that made DDT so terrible for living things?
cannot be eliminated from bodies
nonbiodegradable
killed insects
killed humans
25
Define endemic.
an organism is only found in a certain area
A group of organisms in danger of extinction
When an organism is no longer found in a certain area
Organism that is originally from a different place, but thrives in another
26

increases
decreases
27
What can you do to protect not only 1 species but many including their habitat and interaction?
protect the entire ecosystem
protect the water
protect the air
protect only 1 species
28
Why is biodiversity so important?
provides food and goods
It's a natural resource
it's nice to have lots of animals around
provides medicine
29
What is the impact of ocean acidification on marine organisms that build shells?
They build shells faster
Can’t build shells, and shells dissolve
Nothing, shells do great in a more acidic ocean
They die immediately
30
