Ecosystem and Biodiversity

What is an ecosystem?

• A community of living organisms in conjunction with the nonliving components of their environment.

• A type of musical instrument

• A mathematical equation

• A type of weather phenomenon

Name the components of an ecosystem.

• Biotic factors and abiotic factors

• Sunlight and water

• Plants and animals

• Living organisms and non-living organisms

Why is biodiversity important for ecosystems?

• Biodiversity only benefits individual species, not the ecosystem as a whole

• Biodiversity has no impact on ecosystems

• Biodiversity ensures resilience, stability, and productivity by maintaining the balance of the ecosystem.

• Ecosystems function better with limited species diversity

Explain the concept of genetic diversity.

• Genetic diversity only applies to plants, not animals

• Genetic diversity refers to the number of chromosomes in an organism

• Genetic diversity is the same as genetic modification

• Genetic diversity is the variety of different versions of genes within a species.

How does biodiversity contribute to ecosystem stability?

• Biodiversity leads to ecosystem instability due to lack of specialization

• Biodiversity provides redundancy and resilience to ecosystems, making them more stable and able to withstand environmental changes.

• Biodiversity has no impact on ecosystem stability

• Biodiversity decreases ecosystem stability by introducing competition

Define ecosystem services.

• The study of ecosystems

• Benefits that animals obtain from ecosystems

• Benefits that humans obtain from ecosystems.

• Services provided by humans to ecosystems

What are keystone species and their role in an ecosystem?

• Keystone species are species that have a disproportionately large effect on their environment relative to their abundance. They play a crucial role in maintaining the structure and function of an ecosystem.

• Keystone species are species that have no impact on their environment.

• Keystone species are species that are always the most abundant in an ecosystem.

• Keystone species are species that only affect their own population size.

Discuss the impact of human activities on biodiversity.

• Human activities have a positive impact on biodiversity by increasing species diversity.

• Human activities do not affect biodiversity in any way.

• Human activities only impact biodiversity in a minor and insignificant manner.

• Human activities have a negative impact on biodiversity by disrupting ecosystems and causing the extinction of many species.

Explain the difference between species richness and species evenness.

• Species richness is the measure of how evenly distributed species are in an ecosystem, while species evenness is the total number of species.

• Species richness is the variety of species, while species evenness is the relative abundance of each species.

• Species richness is the same as species evenness.

• Species richness is the total number of individuals in a population, while species evenness is the total number of species.

How can we promote biodiversity conservation?

• Encourage overfishing, pollute water sources, disregard conservation laws

• Ignore conservation efforts, promote unsustainable land-use practices, discourage public education

• Protect natural habitats, implement sustainable land-use practices, control invasive species, educate the public, and support conservation efforts.

• Cut down all trees, destroy natural habitats, introduce more invasive species
