Geographic isolation for a long period of time can lead to the creation of a new _______.
Fossil
Environment
Attitude
Species
What best describes evolution?
The change over time in an individual.
The change over time in the environment.
The change over time of allele frequency in a population.
The change over time in number of offspring in a population.
Buffer zones in a protected area helps minimize disturbances like:
Illegal hunting
Predation
Disease spread from domestic animals like pets
Human interactions
Use this index to find the value of biodiversity of a particular ecosystem.
Lincoln Index
Simpsons Index
Population Index
Excel Index
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Convention on Biological Diversity are examples of
organizations that promote poaching.
international organisation on climate change.
international treaties to protect biodiversity.
laws to increase the number of species
What are the benefits of conserving habitat diversity?
Conserving habitat diversity protects all organisms in the habitat.
Conserves only endangered species.
Conservers only humans living in the habitat.
All the options are true statements.
True or False: The higher the species diversity of
a ecosystem, the lower the complexity.
True
False
Why is the quantification of biodiversity important for conservation efforts?
To ensure that the land is used for the exploitation of a resource.
To assist corporations in identifying a new place to harvest a resource.
So qualitative data can be taken
So areas of high biodiversity can be identified and explored
Natural selection is an evolutionary driving force, referred to as “survival of the fittest”. Which of the following options is true about natural selection?
Organisms that have genetic traits that allowed them to survive and reproduce are considered the strongest.
Nature is literally selecting which organisms are going to survive.
The least "fit" organisms are able to survive
None of the options are true about natural selection.
There are 4 steps in the natural selection mechanism. Which statement below is incorrect?
Within a population of one species, there is genetic diversity, which is called variation.
Due to natural variation, some individuals will be fitter than others.
Fitter individuals have a disadvantage and will reproduce less successfully than individuals who are less fit.
The offspring of fitter individuals may inherit the genes that give that advantage.
Speciation is the formation of new species when populations of a species become isolated and evolve differently from other populations. What environmental change or changes happen that can lead to speciation?
Island Formations
Climate Change
Sea Level Change
All the options are correct.
What is the conflict between exploitation, sustainable development, and conservation in tropical biomes?
Conflict of LEDC of protecting their tropical biomes versus exploiting their resources to become MEDC.
Conflict of LEDC of protecting their environment to not become a MEDC.
There isn't a conflict in LEDC's of conserving their tropical rainforest biomes.
All the options are correct
