18 Questions
What is the definition of an ecological niche?
The role played by a species in a biological community
Which of the following is NOT a type of species interaction described?
Predation
What is resource partitioning?
The process when a species develops a new niche by exploiting resources differently
Which of the following is an example of interspecific competition?
A zebra and a giraffe competing for the same patch of grass
Which type of species interaction is described as 'one species benefits and the other is neither harmed nor helped'?
Commensalism
What are keystone species?
Species that play essential community roles
What is the key difference between generalist and specialist species according to the passage?
Generalists are good at exploiting different environments, while specialists are good at living within a narrower set of environmental circumstances.
According to Liebig's Law of the Minimum, what determines the distribution of a species?
The single environmental factor in shortest supply relative to demand.
How did Shelford build upon Liebig's work?
Shelford added that the single environmental factor closest to tolerance limits determines where a particular organism can live.
What is the main reason why today we know that for many species, the interaction of several factors, rather than a single limiting factor, determines biogeographical distribution?
Advances in scientific research have shown the limitations of Liebig's and Shelford's theories.
Which of the following best describes the concept of Liebig's Law of the Minimum?
The single environmental factor in shortest supply relative to demand is the critical determinant in species distribution.
How does the concept of tolerance limits relate to species distribution according to the passage?
Tolerance limits, along with the single limiting factor, collectively determine the biogeographical distribution of a species.
What is the relationship between environmental factors and a species' ability to survive?
Environmental factors have both minimum and maximum levels that a species can tolerate.
What is the role of indicator species in understanding environmental conditions?
Indicator species are organisms that can provide information about environmental conditions in an area.
What are the two main types of adaptation described in the text?
Natural selection and acclimation.
What is the relationship between natural selection and evolution according to the text?
Natural selection is a mechanism that drives evolution.
What is the purpose of the taxonomic naming system described in the text?
The taxonomic naming system is used to classify different species.
What is the relationship between resource partitioning and the evolution of ecological niches?
The evolution of ecological niches is a result of resource partitioning.
