This affects the types of plant species in the community. How would you describe the role of these bears? Engineer Species Biomagnifying Species Mutualist Species Keystone Species Dominant Species

Explanation / Answer

16) answer is green world hypothesis.

Green world hypothesis posits that the balance of predatory carnivores and herbivores prevents destruction of plant life. It is the conjecture that terrestrial herbivores consume relarively little plant biomass because they are held in check by a variety of factors including predators, parasites and diseases.

Predators help keep the world green

17) answer is predation

Mullerian mimicry refers to the phenomenon in which sympatric harmful species share a similar warning signal for mutual benefit against predation.This kind of mimicry has been documented for several tropical groups that is Heliconius butterflies and poisonous Dendrobatidae frogs.

18) answer is melting glacier.

Secondary succession is a series of community changes which take place on a previosly colonised but disturbed or damaged habitat eg. Areas cleaned of vegetation by tree felling ,fire, harvesting , hurricane. Hence soil has to be present for secondary succession to take place.

Melting glaciers revealing rockbis an example of primary succession where there is no dirt or soil where plants or animals can live

19) answer is dominant species

Dominant species is the one that predominates in an ecological community particularly when they are most numerous or form bulk of the biomass...since species no 3 increased the overall number of other species it is dominant species.

20) bears transferring nutrients from rivers to soil is an example of keystone species

Keystone species are species whose presence and role within an ecosystem has a disproportionate effect on other organisms within the system. Keystone species can sometimes act as nutrient vectors as in this case.
