Intro to Ecology

Question 1

Oragnism

Answer 1

Any living thing

Question 1

In which biome would you find permaforst?

Answer 1

Tundra

Question 2

Which ecosystem receives no sunlight?

Answer 2

Deep Ocean

Question 3

Why is excessive nitrogen bad for an aquatic environment?

Answer 3

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

Question 3

True or False:

Plants and animals are able to use nitrogen gas.

Answer 3

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.

Question 4

Give the three ways represented in the diagram that release CO₂ into the atmosphere.

Answer 4

1 - waste and decay

2 - respiration

3 - combustion

Question 5

Abiotic factor

Answer 5

The nonliving parts of an environment

Question 5

Fill in the missing terms.

Answer 5

1 - evaporation

2 - transpiration

Answer 6

Boreal Forest

or

Taiga

Question 7

In what biomes would you expect plants with small needle-like leaves?

Answer 7

Boreal Forest/Taiga and or the Desert

Question 7

What biome is in the picture?

Answer 7

The Tundra

Question 7

What step goes in the blank in the picture of the Nitrogen cycle?

Answer 7

Consumption

Question 8

Which biome has nutrient rich soild but very few trees?

Answer 8

Grassland

Question 9

Examples of Carbon sinks

Answer 9

Forests, the ocean, fossil fuels,

Question 9

Biome with the greatest diversity

Answer 9

Rain forest

Question 10

Biome

Answer 10

Groups of Ecosystems that share similar climates and organisms

Question 11

Give the three processes, represented in the diagram, that release water into the atmosphere.

Answer 11

1 - evaporation

2 - transpiration

3 - respiration

Question 12

Combustion

Answer 12

The burning of fuel.

Question 13

What biome is represented by the graph?

Answer 13

Tundra

Question 14

Where would you expect to find this animal?

Answer 14

Deep Sea

Question 15

Transpiration

Answer 15

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

Question 15

What biome is represented by the graph?

Answer 15

Desert

Question 16

Carbon Sink

Answer 16

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

Question 18

What biome is represented by the graph?

Answer 18

Rain Forest

Question 19

What biome is represented by the graph?

Answer 19

Polar

Question 21

Which biome has 4 seasons?

Answer 21

deciduous forest

Question 22

biotic factor

Answer 22

The living parts of an environment

Question 24

What are the main necessities of life?

Answer 24

Food, water, shelter/space, climate

Question 25

What process fills in the blanks on the diagram?

Answer 25

Photosynthesis

Question 27

Ecology

Answer 27

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

Question 29

Connection between the carbon cycle and the oxygen cycle

Answer 29

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

Question 30

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

Answer 30

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

Question 32

Nitrogen Fixation

Answer 32

The process of turning nitrogen gas into a usable form

Question 33

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

Answer 33

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

Question 34

Eutrophication

Answer 34

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"

Question 35

Fossil Fuels

Answer 35

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

Question 36

Habitat

Answer 36

The specific area in which an organism lives.

Question 37

What biome is represented by the graph?

Answer 37

Deciduous Forest

Question 38

What biome is represented by the graph?

Answer 38

Grassland

Question 39

Fill in the missing terms

Answer 39

1 - photosynthesis 2 - waste and decay 3 - respiration 4 - combustion

Question 41

Climate

Answer 41

The annual precipitation and temperature.

Question 42

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

Answer 42

Boreal Forest or Taiga

Question 43

What causes a dead zone?

Answer 43

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.

Question 44

How does temperature affect an environment?

Answer 44

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