Which combination of items below is incorrect? decomposers – bacteria and fungi pioneer community – lichens and mosses commensalism – symbiosis in which both organisms benefit ecological niche – role played by a species in its natural habitat

Symbiosis in which each organisms benefit ecological niche.

Explanation:

Symbiotic relationship is an interaction between organisms living together in which either they both benefits, or one benefit or parasitic in which the predator cause harm on the prey. Symbiotic relationship can either be mutualistic I.e each benefits from each other, predation or parasitic I e one benefits and cause harm in another.

i think it is true in my reasonment ..

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
