Q

How would you describe rainfall in the grasslands?

A

Irregular and usually not plentiful

1
Q

What are grassland s sometimes called?

A

Prairies

2
Q

How would you describe the temperatures in the grasslands?

A

Cool in winter and warm in the summer. And can be windy.

3
Q

What is a characteristic of the grasslands that make it great for farming?

A

It has fertile soil.

4
Q

What does deciduous mean?

A

Falling off

5
Q

Where are deciduous forests found?

A

Eastern North America, northeastern Asia,and western and Central Europe

6
Q

How would you describe the temperature in the deciduous forests?

A

Warm summer and cool winter

7
Q

What do many trees lose in the winter in deciduous forests? And what does this do?

A

Many trees lose their leaves in the winter. With fewer leaves, less transpiration occurs, enabling trees to conserve water because water is scarce.

8
Q

Where do you find tropical rain forests?

A

Close to the equator

9
Q

What is the climate like in the tropical rain forests?

A

Hot and humid with abundance of rainfall

10
Q

What does the climate in a tropical rain forests allow for?

A

Enormous variety of species - it is home to more species than an other land biomes combined.

11
Q

Where are temperate rain forests found?

A

In some Pacific Northwest areas

12
Q

What does temperate mean?

A

Mild

13
Q

How is the temperature of temperate rain forests compared to tropical rain forests?

A

The temperatures are lower than tropical rain forests and rainfall is plentiful.

14
Q

List the Freshwater ecosystems that are found in Louisiana.

A
  1. Ponds and lakes
  2. Streams and rivers
  3. Wetlands
  4. Estuaries
15
Q

What are two characteristics of ponds and lakes?

A
  1. Water does not appear to move

2. A layer of green algae sometimes covers the water’s surface

16
Q

What are two characteristics of streams and rivers?

A
  1. Have moving water

2. Organisms have adaptations to keep from being swept away.

17
Q

What are some adaptations that the organisms in streams and rivers have?

A
  1. Reeds have roots that anchor them to the bottom.
  2. Fish have streamlined bodies to help them swim in the currents.
  3. Other animals have hooks and claws that help them cling to rocks and other objects.
18
Q

Where are the wetlands found in Louisiana?c

A

Coastal Louisiana

19
Q

What percentage of the wetlands in the United States are in Louisiana?

A

40%

20
Q

What do the wetlands include?

A

Swamps, marshes and bogs

21
Q

Why are wetlands important today?

A
  1. They are rich in plant life
  2. Provide a home for many living things
  3. Important breeding ground for birds and other animals
  4. Serve as a natural water filter
  5. Provide flood protection and erosion control
22
Q

What is different about estuaries?

A

They contain a unique combination of salt and fresh water. It has less salty than oceans but is saltier than water in rivers.

23
Q

The plants and animals that live in estuaries have what that helps them survive the variations in salt content (or salinity)?

A

Adaptations

24
Q

Why are estuaries an important natural resource?

A

Most fish species caught in the United States each year spend part of their lives in estuaries.

25
Q

What percentage of the Earth’s surface does the ocean cover?

A

70%

26
Q

Why is the ocean important?

A
  1. Plays an important role in the water cycle

2. Contains nutrients that support a variety of life forms

27
Q

What does the Ocean Food Chain include?

A
  1. Plankton - live near the surface of the water
  2. Nekton - animals that swim through the water
  3. Benthos - organisms that live on or near the ocean floor
28
Q

What is the Ocean divided into?

A

Regions

29
Q

What are the factors that effect living things in different regions?

A
  1. Tides
  2. Temperature
  3. Salinity
  4. Water pressure
  5. Amount of sunlight penetrating the water
30
Q

What does the sunlight do near the surface of the ocean?

A

Warms the water and provides energy for different photosynthesis species.

31
Q

Almost no sunlight reaches depths greater than what? What does this cause?

A

200 meters (or 656 feet). Depths beyond this are increasingly dark and cold and photosynthesis does not occur here so organisms feed on each other and on materials that sink down from the ocean’s surface.
