The struggle for survival between organisms or populations that use similar resources and occupy similar niches. Interspecific competition refers to competition between populations that may drive a population out of a community or push it to evolve a different niche to reduce competition. Intraspecific competition refers to competition between individuals of the same species.
Two types exist - interspecific and intraspecific. Interspecific completion exists when two or more species use one or more limited resources such as food, attachment sites protective cover, or dissolved ions. Intraspecific competition exist when individuals of a single species compete for limited resource needed for survival and reproduction. This form of competition includes the same resources involved in interspecific competition as well as mates and territories. It is generally more intense than interspecific competition because resource needs are essentially identical among conspecific. See NICHE.
Two or more organisms attempting to occupy or use the same niche or resource in an environment at the same time.
Interaction between organisms to struggle for limited, shared resources (space, food, water, fuel, etc.).
An interaction between or among two or more individuals or species in which exploitation of resources by one affects any others negatively.
a powerful form of interaction that occurs when the same or different species living together in a community utilize the same resources to fill their needs; example: plants competing for the uptake of nitrogen or water.
use or defense of a resource by one individual that reduces the availability of the resource to other individuals.
The process in which 2 or more organisms both require a resource which is in short supply. The process results in a decrease in fitness for both organisms.
The struggle among trees for sunlight, nutrients, water, and growing space. Competition goes on among both the roots and crowns of trees.
The interaction between two organisms for the same resource which is in short supply (for example, food)
Attempts by two or more individuals or organizations to acquire the same goods, services, or productive and financial resources. Consumers compete with other consumers for goods and services. Producers compete with other producers for sales to consumers. View Capstone Lesson(s) that address this concept
a mutually negative interaction between two or more species (interspecific) or individuals (intraspecific) that does not involve mutual predation
When two or more organisms have the potential for using the same habitat or resources.
The simultaneous demand by two or more organisms or species for an essential common resource that is actually or potentially in limited supply (exploitation competition), or the detrimental interaction between two or more organisms or species seeking a common resource that is not limited (interference competition).
Interactions within or among populations resulting from demand for a resource exceeding supply.
The simultaneous demand by two or more organisms for limited environmental resources, such as nutrients, living space, or light.
Plants and animals compete for scarce resources in order to survive. more.
an interaction that occurs between individuals when both attempt to use the same resource.
A relationship between two organisms where both demand the same resources, such as food, water, living space, or light. See the Relationships page for more explanation.
A relationship in which individuals of the same species or of different species living in the same habitat compete for resources. An example is the Galapagos tortoise competing with goats for vegetation.
Organisms have a wide variety of strategies that help them gather resources. They may compete with each other for resources such as water, food, shelter, space and mates. Through competition, species are strengthened in their ability to cope with the difficulties. Not only is one who gets the resource strengthened, but also the one that does not. The 'loser' is forced to search elsewhere and thus is strengthened too—possibly more so than the 'winner'! Not only do organisms compete, but they also work together. On the windswept, icy ridgelines and peaks in the North Cascades, alpine plants clump together to form what researchers call cushion plants. They blanket each other from the wind and cold.
or Compete)—any interaction that is mutually detrimental or harmful to both participants, occurring between species that share limited resources such as food or space. The struggle for limited resources.
In a forest, plants, animals and trees compete for water, sunlight and nutrients.
Species who want the same light or nutrition from the soil are said to be in competition. Exotic Invaders compete with native plants for light, water and nutrients.
a type of behavior that goes on between two or more living things that require the same resource (food, water, mate, space)
The struggle between individuals or groups of living things for common necessities, such as food or living space.
Terms Commonly used in Management Plans] [ Forest Stewardship] The struggle among trees for sunlight, nutrients, water and growing space. Every part of the tree, from the roots to the crown, competes for space and food.
whakataetae The fight for resources.
A process of struggling between or among organisms of the same species (intraspecific) or different species (interspecific) for light, water, essential elements, or space within a trophic level, resulting in a shortage of essential needs for some individuals or groups.
Interaction between members of the same population or of two or more populations using the same resource, often present in limited supply.
( Ecol.). The struggle for the available food, light and moisture, which takes place among species and individuals in an assemblage of plants.
Interaction in which both species are inhibited. Examples: deer and elk or sheep in the same area; swifts and swallows over the same pond, feeding together. (Compare to amensalism, commensalism, mutualism, neutralism, parasitism, symbiosis.)
A more or less active demand on the part of two organisms for some commodity (space, food, etc.) that is inadequate to provide for all organisms present. ( 15)
This is the struggle between organisms to gain a sufficient supply of a scarce resource e.g. Grasses and dandelions compete for water.
occurs between organisms using a finite resource, whether they are of the same or different species.
The demand for a common resource, including space or other conditions, by two or more organisms, in an environment where resources or desired conditions are actually or potentially limited.
A variety of plants or animals vying for certain resources, such as food, moisture, nutrients, or sunlight.
Two or more individual organisms of a single species (intraspecific competition) or two or more individuals of different species (interspecific competition) attempting to use the same scarce resources in the same ecosystem.
the active demand of two or more organisms for the same limited resource (i.e. space, nutrients, water, food, female).
one of several types of symbiotic relationships between the individuals of two (or more) different species. In a competitive relationship neither species benefits (see symbiosis).
occurs when a number of organisms of the same or of different species compete for common resources that are in short supply, such as food, space, or mates.
An interaction between two (or more) organisms (or species), in which, for each, the birth and/or growth rates are depressed and/or the death rate increased by the other organisms (or species).
An interaction in which two organisms remove from the environment a limited resource that both require, and both organisms are harmed in the process. Competition can occur between members of the same species and between members of different species.
The struggle between trees to obtain sunlight, nutrients, water and growing space. Every part of the tree, from the roots to the crown, competes for space and food.
One of the biological interactions that can limit population growth; occurs when two species vie with each other for the same resource.
Interaction where two or more organisms in the same space require the same resource (e.g., food, water, nesting space, and ground space) which is in limiting supply to the individuals seeking it. Competition can occur at the interspecific or intraspecific biotic levels. Competition may also be the result of two different processes: exploitation or interference.
The interaction between organisms trying to obtain resources such as food, water, shelter, mates, nesting sites in an area
an interaction between members of the same population or two populations resulting from a greater demand than supply for a mutually-required resource.
Competition within and between species is an important topic in biology, especially in the field of ecology. Competition among members of the same species is known as intraspecific competition. Competition is also present between species is known as interspecific competition.
