Many species are introduced into new areas every day through ballast water and international shipping; however, not all of these species become established or invasive. Which of the characteristics would be the most likely in a species that would establish itself and become invasive?

For a introduced species to be invasive species, there needs to be certain characteristics of the species.

Invasive species are the species that belong to some other place and are introduced to a new place by means of any human interference. But many species are often transferred from one place to another. But not all of them remain there as an invasive species. This is because for being an invasive species, they need to have certain characteristics:

A. They need to have high rate of reproduction.

B. They need to have short dormancy periods.

C. They need to have high generic variability.

D. They need to be polyphagous and gregarious.

E. They need to have high dispersal rate and great adaptability.

F. They need to have phenotypic plasticity.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
