Example Question #1 : Explain How Animals May Change Due To Environmental Changes
Environmental changes cannot cause problems for animals.
False
True
False
This is a false statement. Environmental changes can cause significant problems for animals. If humans cut down a forest to build a new neighborhood, animals are displaced, maybe without homes, or food sources are lost. These would be terrible changes to the environment that would have long-lasting effects on animals.
Example Question #1 : Explain How Animals May Change Due To Environmental Changes
Birds that are migrating to California usually stop along the way to rest, eat, and drink water. The birds head to California to get away from the frigid weather in Canada. They would not survive without migrating. This year as the birds land at their usual stopping points, they notice it is hotter and dryer than average. As humans, we realize we are in a drought, but the birds do not know this. They are struggling to make the rest of the journey because it is too hot, and there is no water to drink.
How could the animals adjust their behaviors because of the environmental changes?
The birds could stop migrating and just stay in the cold.
The birds could bring water with them on the long journey.
Birds cannot adjust their behaviors, so they are doomed.
The birds may have to take a different route to their destination.
The birds may have to take a different route to their destination.
The birds are facing more than one problem caused by the environment in this scenario. They have to get to California to stay out of the cold weather in Canada, but there is nowhere to rest with food and water on their current route. The birds may have to change their course to avoid the drought-ridden areas to survive the migration.
Example Question #11 : Environmental Changes That Cause Problems
What is a negative effect that an environmental change may have on an animal?
A baby bird fell out of its nest and is now separated from its family.
Jacey got a new puppy for a pet, and he loves fetching sticks in the yard.
Spiders are nocturnal, so they hunt their food at night.
New highways were built, and now the animals are being hit while trying to cross.
New highways were built, and now the animals are being hit while trying to cross.
Animals can suffer adverse consequences that require them to change their behavior to survive. If animals are used to crossing through a wooded area to get to a food or water source, they will continue to do so even after a road or neighborhood is built. Animals will have to change this behavior to avoid being hit by vehicles.
Example Question #1 : Explain How Animals May Change Due To Environmental Changes
What does the term environmental change mean?
When the weather changes from hot to cold
There is not a definition or meaning for the term environmental changes
A disturbance of the environment that causes changes
Human activities that create a new environment
A disturbance of the environment that causes changes
An environmental change is a disturbance that causes changes. It can be human-made or something caused by nature. It can cause plants and animals to adjust and adapt their behaviors to the new environment to survive.
Example Question #3 : Explain How Animals May Change Due To Environmental Changes
Which answer choice is an example of a change that an animal would NOT be able to make due to the environment changing?
Bat's improve their eyesight so they can see more insects as some species start to disappear.
Birds move to taller trees for nesting to stay away from neighborhood cats.
Orcas expand their hunting grounds so they can collect more food.
Alligators move to other water sources that have more food available due to overfishing.
Bat's improve their eyesight so they can see more insects as some species start to disappear.
Animals often have to change their behaviors to adapt to changes in the environment. Bats would not be able to improve their eyesight to locate more insects suddenly. Bats have poor vision and use echolocation to find food; they cannot control their sight to make it easier for locating bugs. This is a change that they would not be able to do.
Example Question #1 : Explain How Animals May Change Due To Environmental Changes
Environmental changes will only affect animals if they make temperatures warmer.
False
True
False
This is a false statement. Environmental changes can cause significant problems for animals. These effects are not solely because of temperatures rising. If temperatures dropped and animals were not well-adapted or equipped to deal with the change, they may not survive. If forests are cut down, droughts occurred, or massive flooding engulfed an area, animals would be affected. These would be terrible changes to the environment that would have long-lasting effects on animals.
Example Question #1 : Explain How Animals May Change Due To Environmental Changes
Birds that are migrating to California usually stop along the way to rest, eat, and drink water. The birds head to California to get away from the frigid weather in Canada. They would not survive without migrating. This year as the birds land at their usual stopping points, they notice it is hotter and dryer than average. As humans, we realize we are in a drought, but the birds do not know this. They are struggling to make the rest of the journey because it is too hot, and there is no water to drink.
What will most likely happen to the birds because of the severe drought?
They will dig deep into the ground to find water sources.
They will have to turn around and go home.
There is no way to predict what will happen to the birds.
They will not make the journey and they will die.
They will not make the journey and they will die.
The birds are facing more than one problem caused by the environment in this scenario. They have to get to California to stay out of the cold weather in Canada, but there is nowhere to rest with food and water on their current route. The birds will likely not make the journey and die if they do not have access to water. It is improbable that the birds will make the trip back home due to exhaustion, and they cannot dig into the ground for water sources.
Example Question #2 : Explain How Animals May Change Due To Environmental Changes
What is a positive effect that an environmental change may have on an animal?
Jackson's Boy Scout troop installed new bat houses in the local park.
Jacey got a new puppy for a pet, and he loves fetching sticks in the yard.
Spiders are nocturnal and hunt at night, so I set up large lights in my yard for them.
A baby bird fell out of its nest and is now separated from its family.
Jackson's Boy Scout troop installed new bat houses in the local park.
Animals can suffer adverse consequences that require them to change their behavior to survive, but there are also positive effects of environmental changes. "Jackson's Boy Scout troop installed new bat houses in the local park" is the correct answer because this adds shelter for bats, which is positive, and it will bring more bats to the area to eat pesky insects.
Example Question #3 : Explain How Animals May Change Due To Environmental Changes
Which answer choice is an example of a change that an animal would be able to make due to the environment changing?
Bat's improve their eyesight so they can see more insects as some species start to disappear.
All birds move to Texas because the weather is pleasant year-round.
A cat hides under a car to stay dry when caught in a rainstorm.
Alligators move to saltwater pools because there are better fish.
A cat hides under a car to stay dry when caught in a rainstorm.
Animals often have to change their behaviors to adapt to changes in the environment. Cats would be able to hide under cars to escape a thunderstorm and stay dry. This is a change that they would be able to do. The other answer choices are improbably or impossible for animals to do.
Example Question #4 : Explain How Animals May Change Due To Environmental Changes
Polar bears hunt seals through holes in the sea ice. They travel from great distances across sheets of frozen water to find seal colonies. The seals rest on the ice in large groups and raise their pups. When the seals go out to hunt fish they slip into the water from the edge of the ice.
If temperatures rise and the ice begins to melt, what impact could there be for the seals?
Warmer temperatures and melting sea ice would not impact seals.
Seals would not have places to raise their pups and would be exposed to bears.
Melting sea ice and warmer temperatures means the seals will become better swimmers.
The temperature warming and ice melting would mean more summer fun for seals.
Seals would not have places to raise their pups and would be exposed to bears.
Animals may have to change when there are environmental changes that impact their lives. In the case of the seal dealing with the difference in the amount of sea ice, the change would need to be huge to survive. Seals rely on the sea ice for raising their pups and escaping polar bears, so they would either need to adapt and change their offspring-rearing techniques or find another place to live. These changes would be challenging, and the seals may not survive.
