Front

What is the bottleneck effect in population genetics?

Back

The bottleneck effect is a sharp reduction in the size of a population due to environmental events or human activities, leading to a loss of genetic diversity.

Front

How does a natural disturbance affect genetic diversity in a species?

Back

A natural disturbance can lead to a bottleneck effect, which decreases the genetic diversity of the affected species.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of species, genetic diversity, and ecosystem diversity.

Front

What is biodiversity richness?

Back

Biodiversity richness is the number of different species present in a given area.

Front

What is biodiversity evenness?

Back

Biodiversity evenness measures how evenly the individuals in a community are distributed among the different species.

Front

Which type of ecosystem service is provided by obtaining lumber from a forest?

Back

Obtaining lumber from a forest is considered a provisioning ecosystem service.

Front

What factors can influence biodiversity in an ecosystem?

Back

Factors influencing biodiversity include habitat destruction, climate change, invasive species, and natural disturbances.

Front

What is the relationship between habitat size and biodiversity?

Back

Generally, larger habitats support more species and higher biodiversity due to greater availability of resources and niches.

Front

How do invasive species affect native biodiversity?

Back

Invasive species can outcompete native species for resources, leading to a decline in native biodiversity.

Front

What is the significance of genetic diversity in a population?

Back

Genetic diversity is crucial for the adaptability and survival of a population, allowing it to respond to environmental changes.
