Test 2

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following is NOT a method of ex situ conservation?

Botanical gardens
Cryopreservation
National parks
Zoological parks
3

National parks are an example of in situ conservation, whereas botanical gardens, cryopreservation, and zoological parks are ex situ conservation methods.

Which of the following is NOT a component of genetic diversity?

Variation within a population
Differences between populations of the same species
Diversity of species in an ecosystem
Different alleles of genes
3

Genetic diversity refers to variations within a species, whereas species diversity deals with the number of species in an ecosystem.

Which human activity has contributed most to species extinction in the last 500 years?

Habitat destruction
Natural disasters
Plate tectonics
Solar radiation changes
1

Habitat destruction, mainly due to deforestation and urbanization, is the leading cause of species extinction in the last 500 years.

Which of the following is an incorrect statement about biodiversity conservation?

Conservation efforts help prevent species extinction.
Ex situ conservation includes seed banks and zoos.
Conservation is unnecessary for ecosystem stability.
In situ conservation protects species in their natural habitats.
3

Conservation is crucial for maintaining biodiversity and ecosystem stability.

Which of the following is an example of an extinct species?

Bengal Tiger
Dodo
Snow Leopard
Olive Ridley Turtle
2

The dodo, native to Mauritius, became extinct due to excessive hunting and habitat destruction.

Which of the following is incorrect about genetic diversity?

Genetic diversity helps species adapt to environmental changes.
Higher genetic diversity reduces the risk of extinction.
Genetic diversity has no role in evolution.
A population with low genetic diversity is more vulnerable to diseases.
3

Genetic diversity is essential for evolution as it allows natural selection to act on variations within populations.

Which region of the world has the highest estimated number of undiscovered species?

Polar regions
Temperate forests
Tropical rainforests
Deep ocean trenches
3

Tropical rainforests are believed to have the highest number of undiscovered species due to their high species richness and unexplored areas.

Which of the following conservation strategies is an example of in situ conservation?

Botanical gardens
National parks
Zoological parks
Seed banks
2

National parks protect species in their natural habitats, making them an example of in situ conservation.

Which of the following statements about biodiversity is correct?

Biodiversity includes genetic, species, and ecosystem diversity.
Biodiversity is higher in temperate regions than in tropical regions.
Species richness is uniform across all ecosystems.
Only plants contribute to biodiversity.
1

Biodiversity consists of genetic, species, and ecosystem diversity. It is highest in tropical regions and varies among ecosystems.

Which of the following human activities has led to the introduction of invasive alien species?

Deforestation
International trade and transport
Climate change
Soil erosion
2

International trade and transport have contributed to the spread of invasive species, disrupting native ecosystems.
