LS2.5 & LS2.4

​LS2.5 Invasive species

​Remember pine beetles?

​Invasive species spread many ways. Let's think about how pine beetles can spread. Feel free to Google this for ways they spread.

​

​Type a way they spread in chat.

​​LS2.5 Invasive species

How do mountain pine beetles get from one tree to another?

​

Then how can we slow down their spread?

​

​Put this in chat.

​

​Let's do a Benchmark question now.

Multiple Choice

Laurel will disease is caused by an invasive fungus. The fungus infects several trees in north central Tennessee. The fungus destroys water transport tissues in the infected trees, causing them to die in weeks or months after infection.

How can people keep the fungus from spreading across Tennessee?

• Provide extra water to trees that are infected with laurel wilt disease

• Use handsaws instead of electric saws to cut down trees near trees that are infected with laurel wilt

• Cut down trees that have died from laurel wilt, and turn them into mulch for gardening

• Do not transport firewood away from an area where laurel wilt disease has been reported.

​LS2.4 Biomes

What kinds of adaptations do these organisms have?

​

​What features of the desert biome requires these adaptations?

​​LS2.4 Biomes

What kinds of adaptations do these organisms have?

​

​What features of the tundra biome requires these adaptations?

Multiple Choice

Many animals that live in a grassland have features such as long legs or wings that help them migrate. Which abiotic factor in the grassland requires these features in the animals?

• The grassland has very few shaded areas.

• The grassland has long periods of drought.

• The grassland has soil that absorbs water quickly.

• The grassland has areas of high and low elevations.
