variation of genes within a species or population in a given area

Answer

variety of ecosystems in a given area

Answer

system made up of all the living and nonliving things in a given area

Answer

disturbance in the environment conditions that cause genetic changes to occur in organisms

Question 5

How do biodiversity and stability work together?

Accepted Answer

The higher the biodiversity, the greater the stability of the ecosystem.

Answer

The lower the biodiversity the greater the stability of an ecosystem.

Answer

The higher the biodiversity, the less stable the ecosystem

Answer

Biodiversity has nothing to do with ecosystem stability.

Question 6

High biodiversity is

Accepted Answer

having a lot of variety of different organisms.

Answer

having a lot of the same organism.

Answer

having a few of the same organism.

Answer

only having one of each organism.

Question 7

Which ecosystem is more likely to survive a change in the environment?

Accepted Answer

One with High biodiversity

Answer

One with Low biodiversity

Question 8

A wetland being drained so a housing development can be built is an example of ____________.

Accepted Answer

habitat destruction

Answer

over exploitation

Answer

pollution

Answer

conservation

Question 9

Habitat restoration can have a positive impact on biodiversity in an area.

Accepted Answer

True

Answer

False

Question 10

A small marine area has phytoplankton as its only producer. Should the marine biologist be concerned about this ecosystem?

Accepted Answer

Yes, this ecosystem has low biodiversity. Without a producer the herbivores will die out leaving no food.

Answer

No the fish do not need the phytoplankton. Since there are so many fish, there is high biodiversity.

Answer

Yes, this system has high biodiversity; however the fish can adapt and get food from another source.

Answer

Yes, the fish will overate to get all of the phytoplankton that is left, then they will die.

Question 11

When there is higher biodiversity...

Accepted Answer

there is more diversity and higher sustainability of life.

Answer

more organisms are likely to die because they can't adapt to environmental changes.

Answer

there is less diversity.

Answer

there is more diversity and lower sustainability of life

Question 12

Why is biodiversity in an ecosystem so important?

Accepted Answer

Because having a high biodiversity allows ecosystems to withstand disturbances (major changes).

Answer

Because it can help humans where to determine good places to develop farm land.

Answer

Because places that have a healthy biodiversity are unaffected by major disturbances.

Answer

Because having a high biodiversity allows for fewer opportunities of competition for similar resources.

Question 13

What happened to the biodiversity in Yellowstone national forest with the addition of wolves to that temperate forest ecosystem?

Accepted Answer

Increased

Answer

Decreased

Answer

Stayed the same

Question 14

A reduction in the variety of pollinating insects would negatively affect the plant populations that depend on them. Which of the following describes the most serious impact this would have on humans?

Accepted Answer

Crops that humans use for food would be reduced

Answer

Plants that don't need insects to pollinate would die

Answer

People would have to build new homes

Answer

There would be a decrease in the availability of soil

Question 15

A dark-eyed junco is a type of sparrow with white tail feathers. The white tails give males a high chance to be chosen as a mate. This species lives in forests in North America. Increasing air pollution has affected the white color on the tails and the sparrow species' mating process.

Which is the best solution to protect the junco's mating process?

Accepted Answer

Limiting the amount of development near the forest, therefore reducing the amount of air pollution?

Answer

Moving the juncos to a different forest so they can adapt to different trees

Answer

Growing various types of food for the juncos in the forest, thereby increasing the amount of rood for their predators

Answer

Removing old trees from the forest, therefore reducing the amount of habitat available for the juncos

Question 16

A student listed four possible ways that natural resources could be conserved:

1. Water lawns less often.

2. Plant trees and shrubs to decrease soil erosion.

3. Develop more coal mines to increase coal production.

4. Use less fertilizers to decrease pollution in rivers from agricultural runoff.

Which methods would be the most effective at conserving natural resources?

Accepted Answer

1, 2, & 4

Answer

1 & 2

Answer

2 & 4

Answer

2, 3, & $

Question 17

Sea turtles bury their eggs in the sand on beaches. The coastal town observes a population decrease in the nesting sea turtles. The town bans people from the beach during turtle nesting time.

Which problem is being addressed by banning access to the beach during this time?

Accepted Answer

The sea turtles have greater success reproducing, which increases their population.

Answer

The sea turtles are exposed to more pollution from people, which increases their population.

Answer

The sea turtles have less competition for food resources, which increases their population.

Answer

The sea turtles can have less ecosystem space, which increases their population.
