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

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?

Possible Answers:

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

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

Correct answer:

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

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?

Possible Answers:

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

There is not enough information to make a conclusion about the habitats.

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

The habitats that are human-made or human-filled have the same animal diversity as natural places.

Correct answer:

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

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.

Possible Answers:

The den where an animal sleeps and hides its offspring

Home or environment for a plant or animal

Hiding places from predators

A zoo or viewing area that is human-made

Correct answer:

Home or environment for a plant or animal

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.

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

Which habitat shows the most diversity in animal species?

Possible Answers:

Rabbit, Mammal, Green, Spring, Brown

Underwater, Fish, Tropical, Ocean

Desert, Sahara, Camels, Animals, Sand

Antarctica, Penguins, Animals, Tourism

Correct answer:

Underwater, Fish, Tropical, Ocean

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.

Example Question #5 : Observe Animals To Compare Diversity In Various Habitats

Every habitat has the same number and types of animals.

Possible Answers:

False

True

Correct answer:

False

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.

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

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

Possible Answers:

False

True

Correct answer:

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.

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

Which habitat would most likely have the lowest diversity among animal species??

Possible Answers:

Swamp

Tundra

Rainforest

Coral reef

Correct answer:

Tundra

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.

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

Screen shot 2020 06 04 at 9.52.18 am

Which conclusion is not supported by the data table above?

Possible Answers:

The habitats that are natural and humanless have more animal diversity.

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.

Not all habitats have the same levels of animal diversity.

Correct answer:

The habitats that are human-made or human-filled have the same animal diversity as natural places.

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.

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

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

Possible Answers:

No plants

All of the answer choices are correct

Little rainfall

Freezing temperatures

Correct answer:

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.

Example Question #5 : Observe Animals To Compare Diversity In Various Habitats

How does the diversity of animals compare among different habitats?

Possible Answers:

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

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

Correct answer:

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

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.
