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!

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

During a school field trip to a forest, Maya observed the role of decomposers in the nutrient cycle of the ecosystem. Discuss what she learned.

• Decomposers produce energy for primary consumers.

• Decomposers break down dead organic matter, returning nutrients to the soil.

• Decomposers are primary producers in the ecosystem.

• Decomposers compete with primary consumers for food.

What interactions do decomposers have in an ecosystem?

• Decomposers interact with the sun and produce energy for primary consumers.

• Decomposers interact with dead organic matter, dead plants and animals returning nutrients to the soil.

• Decomposers interact with secondary consumers and compete for food.
