One way humans can promote the survival of
organisms in an ecosystem is to
(1) decrease diversity in plant habitats
(2) introduce new consumers to control autotrophs
(3) release extra CO2 into the atmosphere to
help autotrophs
(4) learn about the interactions of populations

Respuesta :

I think it's (4),learn about the interactions of population. that way they can keep up with changes and find new ways to keep the balance in the ecosystem.
