Quick Answer: Which scenario best describes how climate change might affect animal migration?

How does climate change affect animal migration?

Some species may move readily across landscapes or habitats, as warming temperatures and changing ecological conditions alter their habitat. Less mobile species will change their distribution more slowly. Some, such as trees and other plants, will only be able to migrate through reproduction and seed distribution.

Which scenario best describes how climate change my affect animal migration?

Which scenario best describes how climate trends might affect animal migration? Animals found in the Arctic may move south. Animals found at the equator may move north. Animals found in higher elevations will move to lower elevations.

What animals are migrating due to climate change?

Animals in the Arctic, including reindeer and golden eagles, are migrating earlier due to climate change, say researchers who have gathered a huge amount of data to study the behaviour of 86 Arctic species over the past three decades.

How does climate change affect Earth’s oceans quizlet?

How does climate change affect earth’s oceans? The pH level of the ocean will shift to a more acidic environment, leading to stress and the possible extinction of many species of shellfish and corals.

How do climate changes affect migratory and hibernating organisms?

Hibernating species are being affected by warming temperatures to the extent that some species are spending less time hibernating by delaying the onset of hibernation or emerging earlier; being abnormally active can force them to use stored energy before they can replace it.

What will climate change force animals to do?

Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.

Do local environmental changes have no effect on the global climate?

Local environmental changes have no effect on the global climate. … Some scientists believe that global warming will bring about extreme weather.

What are some environmental factors that can cause changes in ecosystems quizlet?

Some environmental factors that can cause changes in ecosystems are extreme weather, disease, land use change, invasive species, and pollution.

How can local environmental changes have global effects?

Changes in local environments can have global effects for several reasons. Animals, like birds, migrate from region to region. A change in one of their environments can cause behavioral changes which will affect other organisms living in these environments. Air and water move among regions.

How does climate change affect animals in the Arctic?

More woody plants, more precipitation, and warmer temperatures compromise the survival of grazing animals such as reindeer and muskoxen. Warmer winter temperatures have also increased the layers of ice in snow, making food more difficult to dig up in winter. Fish are moving as seas warm.

How does migration affect other animals?

But migration can have another important benefit. By allowing animals to escape from habitats where parasites have accumulated and by weeding out infected individuals that are not able to survive the journey, migration can reduce parasite infection in animal populations.

How does climate change affect plants and animals?

One of the most significant impacts of climate change on plants and animals is that it destroys habitats. As the earth’s temperature continues to rise, animals and plants that live and grow in colder climates are struggling to survive and might not find a suitable habitat.

Which scenario best describes how climate trends might affect animal migration quizlet?

Which scenario best describes how climate trends might affect animal migration? Animals found in higher elevations will move to lower elevations.

How does climate change affect Earth’s oceans?

As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea level. … These effects, in turn, could substantially alter the biodiversity and productivity of ocean ecosystems.

How do greenhouse gases cause climate warming quizlet?

⦁ The warm surface of the Earth gives off infrared waves. Greenhouse gases block many of these infrared waves, keeping them inside our atmosphere and heating up the Earth. … When snow melts, the darker exposed surface of the earth absorbs more sunlight, causing the Earth to heat up.
