Screen shot 2020 06 04 at 9.52.18 am

What can you conclude about plant diversity in the parking lot compared to the park with a lake?

 

Possible Answers:

There is the same amount of plant diversity in the parking lot and the park with a lake.

There is not enough information to draw a conclusion.

There is more plant diversity in the parking lot than at the park with a lake.

There is less plant diversity in the parking lot than at the park with a lake.

Correct answer:

There is less plant diversity in the parking lot than at the park with a lake.

Explanation:

When comparing the park with a lake to the parking lot, the observations in the data table show readers that there is less plant diversity in the parking lot. The parking lot is human-made, and there are lots of buildings and cement rather than grass and trees like a natural habitat would have.

Example Question #1 : Observe Plants To Compare Diversity In Various Habitats

What does the term diverse mean? Example: The rainforest has a diverse population of plants. Many of them can only be found in that location.

Possible Answers:

Very delicious or tasty

Strong and muscular

Very few, not many

Being different, having a great variety

Correct answer:

Being different, having a great variety

Explanation:

The term diverse means to be different or have variety. In the Amazon rainforest, there are about 80,000 species of plants, which shows how many different varieties there are. It is one of the most diverse populations of plants on Earth.

Example Question #3 : Observe Plants To Compare Diversity In Various Habitats

The Amazon rainforest has 80,000 species of plants. The ocean has 1 million species of plants. The Sahara desert has 500 plant species.

Which statement is true of these habitats?

Possible Answers:

All of the habitats have large plant populations and are equally diverse.

All of the habitats have large plant populations, but the ocean has the most diverse population of the group.

All of the habitats have large plant populations, but the rainforest has the most diverse population of the group.

All of the habitats have large plant populations, but the desert has the most diverse population of the group.

Correct answer:

All of the habitats have large plant populations, but the ocean has the most diverse population of the group.

Explanation:

These three habitats are very different, and all contain large plant populations. When comparing the diversity or variety of these habitats, the ocean has the more diverse or varied populations of plants. The ocean has 1 million species compared to 500 or 80,000 species.

Example Question #4 : Observe Plants To Compare Diversity In Various Habitats

Which habitat shows the most diversity in plant species?

Possible Answers:

Suspension Bridge, Rainforest, Amazon

Nature, Area, Landscape, Flower, Chan

Caribou, Deer, Reindeer, Stag, Antlers

Tree, Desert, Namibia, Clay Pan, Drought

Correct answer:

Suspension Bridge, Rainforest, Amazon

Explanation:

The habitat that shows the most diversity in plant species is the jungle. In the jungle photo, there are multiple plant species shown, whereas the desert, Arctic, and grasslands show many fewer varieties of plants. The Amazon rainforest has 80,000 plant species, whereas the Sahara desert only has 500.

Example Question #51 : 2nd Grade Science

There are diverse plant species all over the world, and they vary in each habitat.

Possible Answers:

True

False

Correct answer:

True

Explanation:

The statement is true because plant species are diverse and live in many different habitats around the world. Plants adapt to their environment and are perfectly suited to living in that location. Some habitats feature many species of plants, while others only host a few.

Example Question #53 : 2nd Grade Science

Which habitat shows the least diversity in plant species?

Possible Answers:

Drift Ice, Frozen, Sea, Wilderness, Ice

Suspension Bridge, Rainforest, Amazon

Caribou, Deer, Reindeer, Stag, Antlers

Tree Trunk, Forest Floor, Trunk, Roots

Correct answer:

Drift Ice, Frozen, Sea, Wilderness, Ice

Explanation:

The habitat that shows the least diversity in plant species is the Arctic tundra. In the other environments, there are at least one plant species, if not more. The Amazon jungle is home to nearly 80,000 plant species, and forests house a diverse population of plants as well. The grasslands only show one plant species, but depending on the area, there can be more.

Example Question #1 : Diverse Habitats

Which habitat has greater plant diversity? Which piece of the text supports the claim?

  • Amazon Rainforest: In the Amazon Rainforest is rains almost every day. There are very tall trees that create a canopy, and the ground of the forest is covered in plants. The plants on the ground try to grow wide or tall to reach sunlight. The very tall trees can block much of the sunlight.
  • The Sahara Desert: The Sahara Desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions.
Possible Answers:

The Amazon Rainforest; "The very tall trees can block much of the sunlight."

The Sahara Desert; "There are only a few plants, and they have small leaves."

The Amazon Rainforest; "...the ground of the forest is covered in plants."

The Sahara Desert; "The Sahara Desert is made entirely of sand."

Correct answer:

The Amazon Rainforest; "...the ground of the forest is covered in plants."

Explanation:

Plant species are diverse and live in many different habitats around the world. Plants adapt to their environment and are ideally suited to living in that location. Some habitats feature many species of plants, while others only host a few. In the two habitats listed the Amazon Rainforest has a great diversity of plants when compared to the Sahara Desert. The text evidence that supports this claim "...the ground of the forest is covered in plants." illudes to many plants being present in the rainforest.

Example Question #55 : 2nd Grade Science

The Sahara Desert: The Sahara Desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions.

What would the Sahara Desert have only a few plant species?

Possible Answers:

It rarely rains and is dry.

All of the answer choices are correct.

The desert is made of sand.

The ground is very hot.

Correct answer:

All of the answer choices are correct.

Explanation:

The Sahara Desert only has 500 plant species, which may seem like a large amount, but the Amazon Rainforest has nearly 80,000! The reason that the desert has so many fewer plant species and is less diverse is that the ground is scorching, shifts in the wind, is made of sand, and the region receives little to no rain. These conditions make it very difficult for plants to survive unless they are well adapted.

Example Question #61 : 2nd Grade Science

Amazon Rainforest: In the Amazon Rainforest is rains almost every day. There are very tall trees that create a canopy, and the ground of the forest is covered in plants. The plants on the ground try to grow wide or tall to reach sunlight. The very tall trees can block much of the sunlight. There are nearly 80,000 plant species in the Amazon.
 
Why would the Amazon Rainforest be such a diverse plant habitat?
Possible Answers:

The plants have plenty of water.

The plants have no water.

The plants have constant care.

There are no predators to eat the plants.

Correct answer:

The plants have plenty of water.

Explanation:

The Amazon Rainforest is a very diverse plant habitat because it has all of the things a plant could need to grow and survive. The rainforest is a wet, humid, and warm place that offers plenty of water and sunlight. Many animal species rely on these plants to make homes and for food. Plants have adapted to this environment and thrive in the conditions.

Example Question #2 : Observe Plants To Compare Diversity In Various Habitats

Grasslands - The grasslands in the Northern hemisphere are vast, open terrains with flowers and grass. There is enough rain to support small amounts of trees and lots of grass. The soil is thin and dry, and there are often wildfires. The temperatures range from very cold (in the negatives) to comfortable (in the mid-70's).

Why are the grasslands not a more plant diverse habitat?

Possible Answers:

There is not enough rain for all plants.

All of the answer choices are correct.

The soil is thin and dry.

There are wildfires.

Correct answer:

All of the answer choices are correct.

Explanation:

Grasslands are home to many plants and animals, but they are not as plant diverse as one may think. All of the answer choices list reasons why the grasslands don't have an abundance of varying plant species. The soil is thin and dry, and not all plants are adapted to this type of earth. There are frequently wildfires, and many plant species cannot recover after these incidents. Finally, there is little rainfall, so many trees and plants cannot function in this habitat. The plants that live in grasslands and do well have evolved and adapted over many years to live in this type of habitat.
