2nd Grade Science › Observe animals to compare diversity in various habitats

Questions 1 - 10
1

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.

2

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.

4

Which environmental factor could cause an animal population to be less diverse?

Freezing temperatures

Little rainfall

No plants

All of the answer choices are correct

Explanation

All of these environmental factors could cause an animal population to be less diverse. If an animal is not adapted to freezing weather or very little rainfall, they will not have the necessary structures or characteristics to survive. If the animal is an herbivore and there are no plants present, the animal will starve. These are all factors that could limit an animal population.

5

How does the diversity of animals compare among different habitats?

The same animals live in each habitat because they all have similar conditions.

Depending on the conditions in a habitat the animals may vary.

Humans do not know about animal diversity, and it cannot be studied in different habitats.

There is no way to compare the diversity of animals in various habitats.

Explanation

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. Depending on the conditions in each environment, the animals will vary.

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 are many more animals in the parking lot than in the grassy field.

There is not enough information to make a comparison between the two habitats.

There are many more animals in the park with a lake than in the grassy field.

Explanation

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.

Which conclusion is supported by the data table above?

The habitats that are human-made or human-filled have less animal diversity.

The habitats that are human-made or human-filled have more animal diversity.

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.

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.

8

What is a habitat? Example: Giraffes can be found in their natural habitat, the plains of Africa.

Home or environment for a plant or animal

The den where an animal sleeps and hides its offspring

A zoo or viewing area that is human-made

Hiding places from predators

Explanation

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.

9

Which habitat shows the most diversity in animal species?

Underwater, Fish, Tropical, Ocean

Antarctica, Penguins, Animals, Tourism

Desert, Sahara, Camels, Animals, Sand

Rabbit, Mammal, Green, Spring, Brown

Explanation

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.

10

Every habitat has the same number and types of animals.

False

True

Explanation

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.
