The relationship between biodiversity and the number of populations is direct. Biodiversity is the variety of species in an area.
Why does biodiversity matter what is the relationship between biodiversity and number of population?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What is the relationship between species and populations?
Species are made up of populations which is dependant on the geographical area. Some species are spread across a limited area, for instance – island, mountain top etc. The single population in such regions constitute for the entire species.
The implicit assumption in many of these studies is that as population density increases so does the threat to biodiversity. … A meta-analysis of these results found a significant positive population correlation indicating that, on average, species-rich regions and human settlements co-occur.
What is the relationship between population diversity and stability?
As diversity increases, population stability is predicted to decline while the stability of aggregate community proper- ties should increase (May 1974; Tilman 1996; Lehman & Tilman 2000). While empirical work indicates that community stability tends to increase with diversity (Loreau et al.
Is biodiversity and number of species the same?
Biodiversity is a complex term that includes not only the variety of different animals (species diversity) but also the difference between animals of the same species (genetic diversity) and between ecosystems (ecosystem diversity). … Worldwide, about 1.75 million different species have been identified.
How does the growing population affect biodiversity?
Population growth and increasing resource consumption affect biodiversity in two ways: They create pressure to convert wildlife habitat into agricultural and urban land; and. They produce wastes that pollute habitat and poison wildlife.
What is the difference between a species and a population between a population and a community?
Organisms that belong to the same species, form groups, and interact together in the same environment make the level of the population whereas a community has groups of different species living together in an environment. Species are the group of individuals that are genetically related to each other.
How many species make up a population?
A population is a group of one species that live within a particular area so the population of Field Mice in Iowa is different from the population of Field Mice in Africa.
What is an example of a competition relationship?
Interspecific competition occurs when members of more than one species compete for the same resource. Woodpeckers and squirrels often compete for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna compete for the same antelope and gazelle prey.
What is the difference between population size and population density?
population size: the number of individuals in the population. population density: how many individuals are in a particular area.
What is the relationship of organism size to population density?
Summary. Population size is the number of individuals in a population. Population density is the average number of individuals per unit of area or volume. The pattern of spacing of individuals in a population may be affected by the characteristics of a species or its environment.
What is the relationship between human population growth and threats to biodiversity?
The core threat to biodiversity on the planet, and therefore a threat to human welfare, is the combination of human population growth and resource exploitation. The human population requires resources to survive and grow, and those resources are being removed unsustainably from the environment.
