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.
The Sahara Desert; "The Sahara Desert is made entirely of sand."
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 Amazon Rainforest; "...the ground of the forest is covered in plants."
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 #4 : Diverse Habitats
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?
All of the answer choices are correct.
The ground is very hot.
The desert is made of sand.
It rarely rains and is dry.
All of the answer choices are correct.
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 #4 : Observe Plants To Compare Diversity In Various Habitats
The plants have no water.
There are no predators to eat the plants.
The plants have constant care.
The plants have plenty of water.
The plants have plenty of water.
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 #1 : Diverse 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?
There is not enough rain for all plants.
The soil is thin and dry.
All of the answer choices are correct.
There are wildfires.
All of the answer choices are correct.
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.
Example Question #61 : 2nd Grade Science
Jacob went to three different locations and collected observations about the habitat and living things that were there. His data is below.
What can you conclude about animal diversity in the parking lot compared to the grassy field?
There are many more animals in the grassy field than in the parking lot.
There is not enough information to make a comparison between the two habitats.
There are many more animals in the parking lot than in the grassy field.
There are many more animals in the park with a lake than in the grassy field.
There are many more animals in the grassy field than in the parking lot.
Jacob was collecting information about the animals in each habitat that he visited. When making a comparison or seeing how two things are similar, it can be seen that the only animal present in the parking lot is humans. In the grassy field, there are many animals and no signs of humans or buildings.
Example Question #1 : Observe Animals To Compare Diversity In Various Habitats
Which conclusion is supported by the data table above?
The habitats that are human-made or human-filled have the same animal diversity as natural places.
There is not enough information to make a conclusion about the habitats.
The habitats that are human-made or human-filled have more animal diversity.
The habitats that are human-made or human-filled have less animal diversity.
The habitats that are human-made or human-filled have less animal diversity.
When reviewing the data table, scientists and readers can draw a conclusion or make a statement about what the information has revealed. Human-made or human-filled places like the parking lot have fewer animals present than the other locations. When looking at the list of animals from the more natural sites, there are far more species present. This allows us to conclude that there is greater animal diversity in those areas.
Example Question #1 : Observe Animals To Compare Diversity In Various Habitats
What is a habitat? Example: Giraffes can be found in their natural habitat, the plains of Africa.
The den where an animal sleeps and hides its offspring
Hiding places from predators
Home or environment for a plant or animal
A zoo or viewing area that is human-made
Home or environment for a plant or animal
A habitat is a place where an animal or plant lives naturally. It is its home or environment. Different habitats support different animals and plants that must adapt to survive. Habitats can be found all over the world and vary in weather, temperature, location, and species diversity.
Example Question #2 : Observe Animals To Compare Diversity In Various Habitats
Which habitat shows the most diversity in animal species?
The photo of the ocean habitat shows the most diversity. The other images show one animal species where the ocean shows many different types of fish and coral. There are more animals in the desert, Antarctica, and grasslands than what is shown, but from what we can see, the oceans are most diverse.
Example Question #63 : 2nd Grade Science
Every habitat has the same number and types of animals.
True
False
False
The statement is untrue. Each habitat is very different and has animals that are suited to living in that specific environment. The species vary significantly from place to place, as do the number of animals. There are 228,450 known animal species in the ocean, nearly 6,000 animal species in Australia, and almost 1,000 different species in the Florida Everglades alone. Just these three places show such a variance in animal diversity.
Example Question #11 : Diverse Habitats
Humans do not know about animal diversity, and it cannot be studied in different habitats.
False
True
False
In each habitat, there are diverse groups of animals based on living conditions. For example, in a cold-weather habitat, the animals have to be adapted to live in that weather. There are similarities between some of the animals living in each habitat, but across the different habitats, there is great diversity. Humans can study these habitats and take note of the different species to decide how diverse an area is.
