Total questions: 20
Worksheet time: 22mins
We do not know how many species there are, but we know species are becoming extint
True
False
What are the organisms that have been less discovered?
Mammals, birds
fish, reptiles
insects, fungi, bacteria
Extinction of species is
a natural process in evolution
not a natural process in evolution
none of the above
What is the average lifespan of mammals?
10 000 000 years
1 000 000 years
100 000 years
How many mass extinctions have already happened?
5
6
4
Currently we are living in the sixth mass extinction
True
False
The current mass extinction
is caused by environmental factors (abiotic)
is caused by human activity (biotic)
is smaller than the others
What species do well in human-created climates ?
dolphins, fish, crab
dogs, cats, cockroaches, rats
algae, trees, bushes
When HOMO SAPIENS outcompeted NEANDERTHALS and led to their extinction
Second phase of the sixth mass extinction
First phase of the sixth mass extinction
Third phase of the sixth mass extinction
The second phase of the sixth mass extinction consisted on
arrival of humans to new places resulting in loss of megafauna (large animals)
the invention of agriculture which meant humans did not compete with other animals for food, but manipulated the environment for their own use
none of the above
Explain how humans stress the environment
The total number of individuals in an ecosystem is more important than the spreading of different species
True
False
What are the types of biodiversity ?
phenotype, genotype
genetic, species
genetic, species, habitat
Genetic diversity focuses on
the number of individuals plus the number of species in a given habitat
the genetic variety within a species, which determines variation in individuals
the number of different habitats per unit of area in a ecosystem or biome
Explain why biodiversity varies from habitat to habitat (biomes)
What does a diversity index tell us?
The number of different habitats per unit of area in a ecosystem or biome
Both the number of species (richness) and the abundance of each species (number of individuals)
The range of genetic material present in a species which can be lost by domestication and breeding
D=∑i=1nni(ni−1)N (N−1)
Simpson's Diversity Index
Shannon Wiener's Diversity Index
Gini's Diversity Index
In ecosystems, a hotspot is
an area with a very high temperature
the arrival of humans to a new place resulted in loss of megafauna (large animals)
an area where there are unsually high numbers of endemic species
Ecosystem 1 is more diverse than Ecosystem 2
Ecosystem 1 is less diverse than Ecosystem 2
Ecosystem 1 is equally diverse than Ecosystem 2
Diversity Index = 3,89
Diversity Index = 2,35
Diversity Index = 1,83
