Every year the Society for Science and the Public hosts a national science competition for students in 6th, 7th, and 8th grade. The competition, called the Broadcom Math, Applied Science ...
Competition is an interaction between organisms or species in which both require one or more resources that are in limited supply (such as food, water, or territory). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. [2]
Some examples of non-trophic interactions are habitat modification, mutualism and competition for space. It has been suggested recently that non-trophic interactions can indirectly affect food web topology and trophic dynamics by affecting the species in the network and the strength of trophic links.
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
An example of direct competition. 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, but the more fit individual survives and is able to reproduce. [ 1 ]
For example, a slight modification of the assumption of how growth and body size are related leads to a different conclusion, namely that, for a given ecosystem, a certain range of species may coexist while others become outcompeted. [10] [11] One of the primary ways niche-sharing species can coexist is the competition-colonization trade-off ...
Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis. Competition between members of the same species is called intraspecific competition.
[2] [3] [4] Second, interspecific competition results in one species driving a competitor to extinction and becoming dominant in the ecosystem. [2] [3] [4] Third, moderate ecological scale disturbances prevent interspecific competition. [2] [3] [4] The hypothesis is ambiguous with its definitions of the terms "intermediate" and "disturbance".
