Biodiversity and Conservation

What is an ecosystem?

• A collection of plants in a garden.

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

• A group of animals living together in a zoo.

• A network of computers connected to the internet.

Define biodiversity.

• Different species of organisms.

• Number of individuals in a population.

• The study of ecosystems.

• Variety of life forms

What is genetic diversity?

• The number of individuals in a population or species.

• The physical characteristics of a population or species.

• Variety of genetic information within a population or species.

• The geographic distribution of a population or species.

Explain the concept of speciation.

• Speciation is the process by which species reproduce asexually.

• Speciation is the process by which species become extinct.

• Speciation is the process by which species evolve into different genera.

• Speciation is the process by which new species arise from existing species.

Why is ecosystem conservation important?

• Ecosystem conservation is a waste of resources and time.

• Ecosystem conservation only benefits a few species, not the entire ecosystem.

• Ecosystem conservation has no impact on biodiversity or the planet's health.

• Ecosystem conservation is important for maintaining biodiversity, providing essential resources, and supporting the planet's health.

Name three different types of ecosystems.

• forest ecosystems

• urban ecosystems

• terrestrial ecosystems, aquatic ecosystems, and desert ecosystems

• tundra ecosystems

What are the main threats to biodiversity?

• Habitat loss, pollution, climate change, overexploitation, and invasive species.

• Deforestation, urbanization, and genetic modification.

• Disease outbreaks, natural disasters, and deforestation.

• Overpopulation, habitat destruction, and climate change.

How does genetic diversity contribute to the survival of a species?

• Genetic diversity decreases adaptability and resistance to diseases.

• Genetic diversity has no impact on the survival of a species.

• Genetic diversity leads to inbreeding and reduced fitness.

• Genetic diversity increases adaptability and resistance to diseases.

What are the factors that can lead to speciation?

• geographic isolation, genetic drift, natural selection, and mutation

• natural selection, genetic drift, and gene flow.

• geographic isolation, genetic recombination, and gene flow.

• genetic recombination, gene flow, and genetic mutation.

What are some strategies for ecosystem conservation?

• Building more infrastructure, increasing pollution levels, promoting deforestation

• Encouraging unsustainable resource use, ignoring conservation policies, neglecting research and monitoring

• Protecting natural habitats, promoting sustainable resource use, implementing conservation policies and regulations, conducting research and monitoring, and raising awareness and education

• Decreasing awareness and education, destroying natural habitats, implementing harmful regulations
