Q

Why is excessive nitrogen bad for an aquatic environment?

A

Excessive nitrogen causes the algae to grow out of control and can make it block out the sun for other plants.

Q

True or False:

Plants and animals are able to use nitrogen gas.

A

False, bacteria needs to convert the nitrogen gas into a usable form first, then plants can take it in through their roots and animals get it by eating plants, or other animals that ate plants.

Q

Combustion

A

The burning of fuel.

13
Q

What biome is represented by the graph?

A

Tundra

14
Q

Where would you expect to find this animal?

A

Deep Sea

15
Q

Transpiration

A

The process of water being released from a plant into the atmosphere.

15
Q

What biome is represented by the graph?

A

Desert

16
Q

Carbon Sink

A

A natural environment that absorbs and stores more CO2 than it releases

18
Q

What biome is represented by the graph?

A

Rain Forest

19
Q

What biome is represented by the graph?

A

Polar

21
Q

Which biome has 4 seasons?

A

deciduous forest

22
Q

biotic factor

A

The living parts of an environment

24
Q

What are the main necessities of life?

A

Food, water, shelter/space, climate

25
Q

What process fills in the blanks on the diagram?

A

Photosynthesis

27
Q

Ecology

A

The study of organisms and how they interact with each other and their environment

29
Q

Connection between the carbon cycle and the oxygen cycle

A

One cycle cannot exist without the other. Plants depend on animals releasing carbon dioxide and animals rely on plants turning carbon dioxide into oxygen

30
Q

What do the dots in the diagram represent and what is the process they use to convert nitrogen gas to usable nitrogen?

A

The dots represent bacteria and the process used is called nitrogen fixation.

32
Q

Nitrogen Fixation

A

The process of turning nitrogen gas into a usable form

33
Q

What difference would you expect to see between the climate graphs of the rain forest and a deciduous forest?

A

For the deciduous forest the precipitation would be less than in the rain forest, and the temperature would fluctuate much more.

34
Q

Eutrophication

A

A natural process in a body of water when it builds up a concnetration of nutrients which speeds plant growth and eventually chokes out all life creating a “dead zone”

35
Q

Fossil Fuels

A

Buried remains of organic materials that over a long period of time change into fossil fuels like coal, oil, natural gas.

36
Q

Habitat

A

The specific area in which an organism lives.

37
Q

What biome is represented by the graph?

A

Deciduous Forest

38
Q

What biome is represented by the graph?

A

Grassland

39
Q

Fill in the missing terms

A

1 - photosynthesis

2 - waste and decay

3 - respiration

4 - combustion

41
Q

Climate

A

The annual precipitation and temperature.

42
Q

In what biome would you expect to see mainly coniferous trees?

A

Boreal Forest

or

Taiga

43
Q

What causes a dead zone?

A

When the nutrients build up it causes algae to grow and block the sun from submerged plants. Those plants die and cause the oxygen leves to drop, eventually causing all life that connot leave to die.

44
Q

How does temperature affect an environment?

A

Temperature determines the type of precipitation it will get, the adaptations required by plants and animals
