Unit 5 Bronze

Question 1

What is paleobotany?

Answer 1

Study of ancient plants
Involves searching for the earliest evidence of life in rocks more than 3 billion years old.
(Branched from paleontology, the study of ancient plants, animals, and other organisms)

Question 2

Explain how paleobotanists interpret the Earth’s history

Answer 2

Interpret the earth’s history by examining plant fossils.

Question 3

Explain how paleobotanists can describe the type of climate that existed millions of years ago

Answer 3

Paleobotanists study the features that plants have developed to survive in their environment. These scientists are thus able to describe the type of climate that existed millions of years ago

Question 4

What is the Quaternary Period best known for?

Answer 4

It’s Little Ice age

Question 5

The Holocene Epoch started 11,500 years ago. Describe what the climate was like in the early Holocene Epoch.

Answer 5

Warmer climate

Overall warmer than the present

Question 6

How long did the Little Ice Age last and when did it end?

Answer 6

Lasted several hundred years and ended in the 1800’s

Question 7

Does the Earth have natural warm and cool periods?

Answer 7

Yes, does have natural warm and cool periods, a example of this is the Quaternary period (which was cold) and the Holocene Epoch period (which was warmer)

Question 8

What is a temperature anomaly?

Answer 8

A temperature that is different from the average temperature

Question 9

When was the CO2 concentration the greatest? When was it the lowest?

Answer 9

2022-greatest

1959-lowest

Increases

Question 10

What overall relationship do you see between CO2 and temperature?

Answer 10

As CO2 increases, the earth’s temperature increases

As one is going up the other goes up

Question 11

What are some ways that CO2 is released into the air?

Answer 11

Fires, Driving vehicles, Using electricity, burning of coal
Breathing out (Respiration)
Burning of fossil fuels
Metabolism

Question 12

What pattern do you see in the data?

Answer 12

Consistent rise in co2, but it consistently goes up and down throughout the year

Question 13

How do you explain the pattern?

Answer 13

Plants are conducting photosynthesis more during the summer months then winter months. Therefore, there is more carbon dioxide

Question 14

Describe an edge community

Answer 14

A floral community with different vegetation structure and composition than the two adjoining habitats whose common border was its creation

Group of Species that live where 2 habitats meet. Part time in meadow partly in forest

Question 15

How would succession be different in other biomes

Answer 15

In another biome, like a coral reef, there would be a build up of coral on top of one another, eventually giving way to support more consumers

Question 15

What biomes is represented in the activity? Defend your answer

Answer 15

Temperate forest biome

The type of plants

Question 15

Explain why the same consumers don’t live in each level

Answer 15

Each type of consumer needs certain requirements/resources to live in a biome. Therefore, not every habitat’s different level of succession can support the same consumers. As a new succession occurs, there is more space to support different consumers

Certain consumers want certain producers. As the producers are changing in each , the consumers are changing
