DP-IB -ESS-Topic- 3.2- Origin to Biodiversity

What is the origin of species?

• The origin of species is the study of individual organisms within a species.

• The origin of species is the result of genetic mutations in existing species.

• The origin of species is the process of how species become extinct.

• The origin of species is the process of how new species arise and develop over time.

Explain the concept of natural selection.

• Natural selection is the process by which organisms that are best adapted to their environment survive and reproduce, while those less adapted are eliminated.

• Natural selection is the process of humans controlling which species survive

• Natural selection is the process of animals choosing their own traits

• Natural selection is the process of random mutations creating new species

Give an example of adaptation and evolution in a species.

• The adaptation of giraffes to long necks due to stretching to reach tall trees

• The adaptation of the peppered moth (Biston betularia) to industrial pollution in 19th century England, where the dark-colored moths became more prevalent due to their ability to blend in with the soot-covered trees, is an example of adaptation and evolution in a species.

• The adaptation of fish to breathe air and live on land

• The evolution of elephants developing wings to fly

What are biodiversity hotspots and why are they important?

• Areas with moderate levels of biodiversity and not affected by human activities.

• Regions with low levels of biodiversity and not important for conservation.

• Places with high levels of biodiversity but not significant for conservation efforts.

• Regions with high levels of biodiversity under threat from human activities and important for conservation.

How does human impact affect biodiversity?

• Human impact has no effect on biodiversity

• Human impact only leads to positive effects on biodiversity

• Biodiversity is not affected by human impact

• Human impact can lead to habitat destruction, pollution, overexploitation, and introduction of invasive species, all of which can negatively affect biodiversity.

Discuss the importance of conservation in maintaining biodiversity.

• Conservation helps protect and preserve the variety of species and ecosystems on Earth.

• Biodiversity is not important for ecosystems

• Human activities do not affect biodiversity

• Conservation has no impact on biodiversity

Explain the relationship between Plate Tectonics, Evolution, and Biogeography.

• Plate tectonics influence the distribution of species and the formation of new habitats, which in turn affects evolution and biogeography.

• Biogeography is not affected by the movement of tectonic plates

• Evolution is solely influenced by climate change and has no connection to plate tectonics

• Plate tectonics have no impact on the distribution of species or the formation of new habitats

What are mass extinctions and how do they impact biodiversity?

• Mass extinctions have no impact on biodiversity as it only affects a small number of species.

• Mass extinctions increase biodiversity by causing the rapid evolution of new species.

• Mass extinctions reduce biodiversity by causing the loss of a large number of species in a short period of time.

• Mass extinctions only impact biodiversity in a positive way by removing weaker species.

What is the 6th extinction and what are its causes?

• The 6th extinction is caused by the depletion of the ozone layer.

• The 6th extinction is a result of overpopulation of certain species.

• The 6th extinction is the ongoing mass extinction of species caused by human activities.

• The 6th extinction is a natural phenomenon caused by climate change.

How can we contribute to the conservation of biodiversity in our daily lives?

• Use more single-use plastics, support deforestation, plant invasive species, and spread misinformation about biodiversity

• Reduce use of single-use plastics, support local and sustainable agriculture, plant native plants, and educate about the importance of biodiversity

• Ignore single-use plastics, support unsustainable agriculture, plant artificial plants, and deny the importance of biodiversity

• Increase use of single-use plastics, support industrial agriculture, plant non-native plants, and ignore the importance of biodiversity
