2nd Grade Science › Diverse Habitats
Humans do not know about animal diversity, and it cannot be studied in different habitats.
True
False
Explanation
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.
Which habitat shows the least diversity in plant species?
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.

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 Amazon Rainforest; "...the ground of the forest is covered in plants."
The Amazon Rainforest; "The very tall trees can block much of the sunlight."
The Sahara Desert; "The Sahara Desert is made entirely of sand."
The Sahara Desert; "There are only a few plants, and they have small leaves."
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.
Which habitat would most likely have the lowest diversity among animal species??
Coral reef
Rainforest
Tundra
Swamp
Explanation
A tundra would have the lowest diversity among animal species because of the harsh conditions for survival. Antarctica is one example of a tundra habitat. Antarctica is the coldest place on our planet. Temperatures can reach -120oF, and winds can be powerful. There are no plants or animals that can make their homes permanently in central Antarctica. This area has no resources for animals, so they cannot survive.

Which conclusion is not supported by the data table above?
The habitats that are human-made or human-filled have the same animal diversity as natural places.
The habitats that are human-made or human-filled have less animal diversity.
The habitats that are natural and humanless have more animal diversity.
Not all habitats have the same levels of animal diversity.
Explanation
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. This means that "The habitats that are human-made or human-filled have the same animal diversity as natural places." is not supported by the evidence in the data table.
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?
The desert is made of sand.
It rarely rains and is dry.
The ground is very hot.
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.
