Biodiversity Review

Variation happens as a result of the exchange of genetic information as it is passed fromparent to offspring.Which of the following is true about inherited variation?

• Variation can influence the resources that are available to an organism.
• Variation can influence whether organisms are more likely to survive to reproduce.
• Variation can influence the amount of rainfall in an ecosystem
• Variation can influence the amount of available food in an ecosystem

In a population of spiders there are three different sizes: small, medium, and large.
---The large spiders are easily seen by predators.
---Small spiders have a difficult time finding food.
What will most likely happen to this population of spiders after many generations?

• Small and large spiders will mutate
• Medium spiders will be the most plentiful
• Large spiders will learn to hide from predators
• Small and medium spiders will be the least plentiful

Organisms need all of the following things EXCEPT

• Food
• Water
• Shelter
• Ability to hunt

Forests are often preserved to protect biodiversity. This helps preserve the unique characteristics of the organisms that live there. Sometimes these forests are divided into separate sections that are spread out instead of one continuous forest. This is known as forest fragmentation. Which types of organisms will be the least likely to be affected by forest fragmentation?

• herbivorous birds that are able to migrate great distances
• omnivores that hibernate in winter in order to conserve energy
• omnivores that burrow underground deep in to the soil.
• herbivorous mammals that are dependent upon specific plants for food

When there is higher biodiversity

• more organisms are likely to die because they can't adapt to environmental changes.
• there is less diversity.
• there is more diversity and higher sustainability of life.
• there is more diversity and lower sustainability of life

How do biodiversity and sustainability work together?

• The lower the biodiversity the greater the sustainability.
• The higher the biodiversity, the less sustainable the ecosystem
• The higher the biodiversity, the greater the sustainability.
• Biodiversity has nothing to do with sustainability.
