“Which of the following is an outcome of interspecific competition? Both species coexist at population densities greater than would be present if they existed in the same environment without the order? Only one species survives; the other goes extinct. Both species grow at greater rates than would occur if they were present in the same environment without the other. All of the above.”
Answer: Only one species survives, the other goes extinct.
Interspecific competition is a form of competition in which different animal species compete for the same food/territory in the ecosystem.
The result of this competition will be that one of the species will die out and the other species survives because they require the same food/territory to survive but both can’t win.
Interspecific competition can have a significant impact on both individuals and communities, with consequences that extend beyond one species. As adaptations are made to avoid competition, these changes may lead to the evolution of species. This development might result in the displacement of a species from its environment, as well as niche separation and local extinction.
-competition for limited resources
-competition for space
with or without physical contact
Allelopathy in plants
2. species 2 inhibits species 1, and species 1 becomes extinct
3. Individuals of both species inhibit the other species more than their own specie when they are most abundant, most abundant one wins
4. Individuals inhibit their own species more than the other, they coexist
feed at different times
forage in different areas
exploit portion of resources unavailable to others
