What does high species diversity indicate?
A healthy ecosystem with a wide variety of species coexisting.
A lack of competition among species.
An ecosystem that is prone to diseases.
A decrease in the number of species present.
Which habitat exhibits the greatest biodiversity?
A habitat with 15 different species with about 300 individuals each.
A habitat with 10 different species with about 500 individuals each.
A habitat with 20 different species with about 100 individuals each.
A habitat with 5 different species with about 1000 individuals each.
What is a bottleneck in biodiversity?
A process that increases genetic diversity in a population.
A situation where a population's size is significantly reduced, leading to a loss of genetic diversity.
An event that enhances the survival of all species in an ecosystem.
A method of conserving species by increasing their population size.
Why is genetic diversity important?
It allows species to adapt and survive environmental changes.
It increases the population size of a species.
It reduces competition among species.
It enhances the aesthetic value of ecosystems.
How does pollution affect biodiversity?
Pollution can enhance habitats and promote species diversity.
Pollution can degrade habitats, harm species, and reduce biodiversity by creating unsuitable living conditions.
Pollution has no significant impact on biodiversity.
Pollution only affects terrestrial species, not aquatic ones.
What is conservation biology?
A scientific study focused on understanding and preserving biodiversity and ecosystems.
A method of farming that promotes biodiversity.
A type of biology that only studies extinct species.
A branch of biology that deals with the genetic modification of organisms.
What is biodiversity?
The variety of life in a particular habitat or ecosystem, including the number of different species.
The total number of organisms in a specific area.
The study of how species interact with each other.
The process of evolution in different species.
How does biodiversity contribute to ecosystem resilience?
Biodiversity enhances ecosystem resilience by providing a wider range of responses to environmental changes.
Biodiversity decreases ecosystem resilience by limiting species interactions.
Biodiversity has no impact on ecosystem resilience.
Biodiversity only benefits certain species in an ecosystem.
What is an invasive species?
A species that is native to a specific habitat.
A non-native species that spreads widely in a new habitat, often causing harm to native species and ecosystems.
A species that is endangered and protected by law.
A species that has been introduced for agricultural purposes.
What are the advantages of biodiversity to humans?
Biodiversity provides medical uses, recreational opportunities, and industrial resources.
Biodiversity leads to increased pollution and environmental degradation.
Biodiversity reduces the availability of natural resources.
Biodiversity has no significant impact on human life.
What is habitat fragmentation?
A process where large habitats are preserved intact
The division of large habitats into smaller, isolated patches, negatively impacting biodiversity
A method of increasing biodiversity by creating more habitats
The natural evolution of habitats over time without human interference
What is the difference between species richness and species evenness?
Species richness refers to the number of different species in a community, while species evenness measures how evenly individuals are distributed among those species.
Species richness measures how evenly individuals are distributed among species, while species evenness refers to the number of different species in a community.
Species richness is the total number of individuals in a community, while species evenness is the number of species present.
Species richness and species evenness are the same concept, both referring to the diversity of species in a community.
What is an example of low species diversity?
A marsh ecosystem covered by a single species of cattail bulrushes.
A tropical rainforest with a variety of trees and plants.
A coral reef with multiple species of fish and corals.
A grassland with various flowering plants and insects.
What is ecotourism?
Ecotourism is a form of tourism that supports the conservation and sustainable development of ecologically unique areas.
Ecotourism is a type of tourism that focuses on luxury travel experiences.
Ecotourism involves traveling to urban areas to experience local culture.
Ecotourism is a form of tourism that promotes mass tourism in popular destinations.
What is the role of keystone species in an ecosystem?
They are the most abundant species in an ecosystem.
They play a critical role in maintaining the structure of an ecosystem, influencing the types and numbers of other species.
They are always the largest species in an ecosystem.
They have no significant impact on the ecosystem.
