Succession, Biomes & Biodiversity Test Review

What role do pioneer species in Primary and Secondary Succession play?

• They remove dead materials after a disaster

• They build & enhance soil, so that the ecosystem can become more complex & stable.

• They feed top carnivores

• They increase the amount of usable carbon dioxide in the air

The picture shows what type of succession? How do you know?

• primary because it begins with a soil base

• secondary, because it begins with a soil base

• primary because it begins with bare rock

• secondary because it begins with bare rock

What is the difference between biotic and abiotic?

• Biotic are non-living things
• Abiotic are living organisms
• Biotic is life,
  Abiotic is non-living
• Biotic is non-living, Abiotic is living

Why is the Complex food web more stable than the Simple food web?

• Biodiviersity makes sure that all organisms have more than one food source and more than one predator.

• Top predators have more competition.

• The Complex food web has less biodiversity but more herbivores.

In this tundra food web, if grasses were removed what would happen to the sustainability of the ecosystem?

• There would be an overpopulation of arctic hares and lemmings.

• Polar bears would move to a new ecosystem

• The entire ecosystem would be affected because grass is the primary food source for all herbivores in the food web.

• Wildflowers would die out from the ecosystem

As biodiversity increases, the sustainability of an ecosystem...

• Decreases

• Increases

• Stays the same

• All of these are correct
