How does biodiversity affect the sustainability of an ecosystem?

Biodiversity helps the ecosystem remain sustainable.

A species that is responsible for primary succession in an ecosystem is most likely able to...

Carry out photosynthesis.

What is the relationship between ecological succession and equilibrium in an ecosystem?

Ecological succession helps maintain equilibrium in an ecosystem.

A hurricane hits a coastal prairie and destroys the habitat, what kind of succession is this an example of?

Secondary succession.

How does biodiversity affect the sustainability of local ecosystems?

The variety of interactions among the different species helps the ecosystems remain sustainable.

Coral reefs are ecosystems in which their is a high amount of biodiversity. The existence of so many different plant and animal species allows a coral reef to...

The growth of weeds is the first stage of ecological succession, which...

acts to restructure a habitat and allow only the most hardy plants to survive.

Biodiversity affects the sustainability of an ecosystem by...

hardwood forest stage

What is the primary limiting factor of living in the desert?

lack of moisture

Plants adapted to the rainforest have...

leaves with drip tips, climbing vines, smooth bark: buttress roots; dense canopy promotes intense plant competition.

What is the most serious threat to biodiversity?

loss of natural habitat

A student explains that most marine plants are found near the surface of the ocean because the ocean floor does not provide enough minerals for plants. What is the greatest weakness of this explanation?

many plants are found on the ocean floor in the shallows close to shore.

Plants adapted to the tundra are...

small, low growing; dark, hairy leaves to absorb heat; grow in clumps for greater protection from wind and cold; flowers often disk-shaped to collect the sun.

What is the result of ecological succession in a pond?

the habitat has become more stable because more trees have grown in the area.

What is changing as time passes during ecological succession of a pond?

the habitat is becoming more stable as the pond fills up with soil.

The role of ecological succession is to allow a habitat to move through different stages until...

the habitat is home to species that will be able to survive in the area for a long period to time.

Ecological succession occurs in stages, and permits a habitat to allow new species to grow in number as...

the habitat undergoes changes.

The more diverse an ecosystem is...

the more stable it is.

How would the sustainability of a forest ecosystem be affected if the biodiversity of the forest increased?

the sustainability of the ecosystem would increase because there would be more interactions between different species.

What helps a camel prevent dehydration?

they can extract water from their solid wastes, their kidneys are capable of concentrating urine to reduce water loss, and water is absorbed slowly from the camel's stomach and intestines.

When an ecosystem contains many different species, there are usually a high number of links in its food web. How does this affect the sustainability of the ecosystem?
