Total questions: 15
Worksheet time: 45mins
What are foundation species?
Organisms that are at the top of the food chain.
Organisms that make physical changes and help create habitats.
Organisms that are only found in aquatic environments.
Organisms that have no impact on their ecosystem.
What is the difference between species richness and species evenness?
Species richness is the number of individuals in a community, while species evenness is the number of different species.
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 is the total biomass of a community, while species evenness is the diversity of habitats.
Species richness measures the genetic variation within a species, while species evenness measures the reproductive success of species.
What are the main threats to biodiversity?
Habitat destruction, climate change, pollution, overfishing, and invasive species.
Urban development and population growth.
Natural disasters and seasonal changes.
Agricultural practices and deforestation.
What is an ecological niche?
An ecological niche is the role and position a species has in its environment, including all interactions with biotic and abiotic factors.
An ecological niche refers to the physical space a species occupies in a habitat.
An ecological niche is the total number of individuals in a population.
An ecological niche describes the genetic makeup of a species.
What is the role of genetic diversity in species survival?
Genetic diversity decreases a population's ability to adapt to changing environments.
Genetic diversity has no impact on species survival.
Genetic diversity increases a population's ability to adapt to changing environments and resist diseases.
Genetic diversity only affects physical traits of a species.
What is the significance 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.
They are the largest species in an ecosystem.
They have no significant impact on the ecosystem.
What is meant by an organism's optimum range?
An optimum range is an organism's comfort zone where it can thrive.
An optimum range is the maximum temperature an organism can withstand.
An optimum range refers to the geographical area where an organism is found.
An optimum range is the minimum amount of resources an organism needs to survive.
What are the three levels of biodiversity?
Genetic diversity, species diversity, and ecosystem diversity.
Population diversity, community diversity, and habitat diversity.
Morphological diversity, functional diversity, and genetic diversity.
Species richness, species evenness, and ecosystem stability.
What does genetic diversity refer to?
Differences in DNA among individuals of a population or species.
The total number of species in a given area.
The ability of an organism to adapt to its environment.
The physical characteristics of an organism.
How does habitat loss affect biodiversity?
Habitat loss leads to a decrease in biodiversity as species lose their homes and resources.
Habitat loss has no effect on biodiversity.
Habitat loss increases biodiversity by creating new habitats.
Habitat loss only affects plant species, not animals.
What is the impact of invasive species on native biodiversity?
Invasive species can enhance native biodiversity by introducing new genetic material.
Invasive species can outcompete native species for resources, leading to a decline in native biodiversity.
Invasive species have no significant impact on native biodiversity.
Invasive species can help native species thrive by providing new habitats.
What happens to individuals living in the zone of intolerance?
They thrive and prosper.
They will die.
They become leaders in their community.
They adapt and find new resources.
What is the current status of climate change in relation to Earth's history?
Climate change is a new phenomenon that has never occurred before.
Climate change has occurred multiple times throughout Earth's history.
Climate change is solely caused by human activities.
Climate change is only a concern for the future, not the present.
What is biodiversity?
Biodiversity refers to the variety of life in a particular habitat or ecosystem.
Biodiversity is the number of species in a given area only.
Biodiversity is the total biomass of all organisms in an ecosystem.
Biodiversity refers to the genetic variation within a single species.
What is the concept of ecological succession?
A process by which ecosystems remain static over time.
The process by which ecosystems change and develop over time, often following a disturbance.
A method of measuring biodiversity in an ecosystem.
A technique used to restore damaged ecosystems.
