Accepted Answer

Primary succession

Answer

Resource harvesting

Answer

Invasive (non-native) species move in

Answer

Competition

Question 14

How can humans work to ensure our ecosystems remain healthy?

Accepted Answer

Promote increased biodiversity through conservation of rainforests, limiting and preventing invasive species, and responsibly disposing of wastes.

Answer

Limit the number and variety of organisms living in ecosystems (reduce biodiversity).

Answer

Introduce invasive species and pollute ecosystems.

Answer

Convert ecosystems into agricultural areas for farming.

Question 15

What is a pioneer species?

Accepted Answer

The first organism to repopulate an area undergoing ecological succession.

Answer

The last organism to repopulate an area undergoing ecological succession.

Answer

The first animal species to return to an ecosystem.

Answer

The apex predators at the top of an ecosystem's energy pyramid.

Question 16

What are examples of pioneer species during primary succession?

Accepted Answer

Mosses and Lichens

Answer

Bushes and Shrubs

Answer

Oak trees

Answer

A rose bush

Question 17

In a pond, which of the following changes would most likely result in terrestrial succession (turning the aquatic ecosystem into a land ecosystem)?

Accepted Answer

An increased rate of deposition of sediments into the pond.

Answer

An increase in water plants growing in the pond.

Answer

A decrease in the number of decomposers in the pond.

Answer

A decrease in the amount of dissolved oxygen in the water, which would result in the death of large fish in the pond.

Question 18

Which of the following natural events can lead to primary succession?

Accepted Answer

Glacier movement and volcanic eruptions

Answer

Floods and hurricanes

Answer

Wildfires and controlled burns

Answer

Tsunamis and tornadoes

Accepted Answer

The occurrence of a forest fire

Answer

The development of a parking lot

Answer

A glacier retreating

Answer

Humans preserving the natural habitats of native wildlife

Question 20

A hurricane hits a coastal ecosystem and destroys the habitat. Years later, there is an appearance of small plants with rapidly spreading roots on newly formed coastal sand dunes. The vegetation describes --

Accepted Answer

secondary succession.

Answer

a microhabitat.

Answer

primary succession.

Answer

biodiversity.

Question 21

You observe a garden in a schoolyard. Corn, tomatoes, pumpkins, and other crops thrive in the garden. What is most likely true of the soil in this microhabitat?

Accepted Answer

It is deep, dark, and nutrient rich.

Answer

It is thin, acidic, and nutrient poor.

Question 22

How is secondary succession different from primary succession?

Accepted Answer

Secondary succession occurs after a disturbance in an area in which the soil has remained intact.

Answer

Secondary succession occurs after a disturbance in an area that was previously uninhabited.
