1.
Niche overlap indicates
Niche overlap indicates competition between two species for similar resources Niche overlap occurs when two organismic units use the same resources or other environmental variables. In Hutchinson's terminology, each n-dimensional hypervolume includes part of the other or some points in the two sets that constitute their realized niches are identical.
2.
What is a keystone species?
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
3.
Two plants can be conclusively said to belong to the same species if they,
A group of organisms having many characteristics in common and ranking below a genus. Organisms that reproduce sexually and belong to the same species interbreed and produce fertile offspring.
4.
A high density of elephant population in an area can result in
Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals. By contrast, interspecific competition occurs when members of different species compete for a shared resource.
5.
A community is defined as
In ecology, a community is an assemblage or association of populations of two or more different species occupying the same geographical area and in a particular time, also known as a biocoenosis The term community has a variety of uses.
6.
Distribution of different plants geographically is called
Occurring in separate, nonoverlapping geographic areas. Allopatric populations of related organisms are unable to interbreed because of geographic separation. The development of new species as a result of the geographic separation of populations is called allopatric speciation.
7.
Which of the following statements is true regarding individuals of same species?
A group of organisms having many characteristics in common and ranking below a genus. Organisms that reproduce sexually and belong to the same species interbreed and produce fertile offspring.
