Ecosystem and biomes

What are the possible effects of climate change on plant and animal species?

• Alteration of the species composition of biomes

• Shifting of habitat ranges

• Endangerment & extinction

• All answer choices are accurate

How can plants & animals cope as the climate changes?

• Species sweat more to keep cool

• Species shift their range to cooler, higher elevations

• Species shift their range closer to the equator

• Species don't need to cope; they are thriving!

Which of these animals are declining in number & facing extinction from climate ?

• Coral reefs & polar bears

• Jellies & seastars

• Mosquitoes & bark beetles

• Dogs & cats

Why are forests important for mitigating climate change?

• Trees provide building materials

• Forests serve as a sink in the carbon cycle

• Trees are an important food source

• Leaves of trees reflect all sunlight away from the Earth

Dying trees are an issue in relation to climate change because:

• Children will have nothing to climb

• Dead trees can fall on people's houses

• Healthy forests are effective carbon sinks

• Healthy forests are home to a diversity of animal species

In which ecosystem do more than half the world's species live?

• coral reefs

• grasslands

• deserts

• rainforests

The nonliving parts of an ecosystem are called

• abiotic

• biotic

• populations

• bioptic

A stable ecosystem is one where

• the supply of resources is unstable

• energy flows at a constant rate

• populations fluctuate to extremes

• the scales stay balanced with money

Which biome has the coldest climate, but gets little or no precipitation (rain)?

• desert

• tundra

• deciduous forest

• ocean

This biome has four distinct seasons

• desert

• tundra

• deciduous forest
