Multiple Choice

A climatogram is a graph that shows the climate of a particular biome. This is a climatogram

for a tundra biome.

What do the blue bars and red line represent on the graph?

• precipitation and temperature which are biotic factors

• precipitation and temperature which are abiotic factors

• months of the year

• the arctic tundra biome

Multiple Choice

A climatogram is a graph that shows the climate of a particular biome. This is a climatogram

for a tundra biome.

Which statement below describes the ecosystem factors included in a climatogram?

• The climatogram shows the availability of abiotic nutrients during each month.

• The climatogram shows the change in abiotic factors over the course of the year.

• The climatogram demonstrates how biotic organisms survive in this

  biome.

• The climatogram allows scientists to track the availability of biotic factors

Multiple Choice

What does "marine" mean?

• life

• ocean

• abiotic

• rain

Multiple Choice

What is the major difference between freshwater and marine water?

• Temperature

• Sunlight availability

• Salinity

• Bacterial pollution

Multiple Choice

What is a biotic factor that affects the lives of humans?

• The increase in global temperature

• Chemical air pollution from vehicles

• The risk of lightning strikes

• Spread of bacterial infections

Multiple Choice

Which example best illustrates the relationship between an abiotic and biotic factor in an ecosystem?

• A shark consuming a smaller fish for food

• Flowers providing a food source for bees

• Water currents carrying rocks downstream

• Available sunlight affecting how fast a plant grows

Multiple Choice

Which example illustrates the relationship between two biotic factors in an ecosystem?

• A frog catching a fly to consume for energy

• Warm water rising to the surface of a river which creates water movement

• Rocks providing shelter for fish to protect themselves from predators

• A storm with strong winds causes the soil to be displaced
