Answer:
The correct answer is "altering the equilibrium of ecosystems".
Explanation:
Ecosystem have a very complex and sometimes intricate equilibrium. Each species in an ecosystem have a role in the food chain, therefore, if humans affect the behavior of one species, undoubtedly, another species will be affected. In this case, insect populations are increasing as a result of birds modifiying they migratory behavior due to the presence of discarded food in the landfills. Most likely the increased insect populations will affect the plants population as well, creating a series of events that alter the equilibrium of the ecosystems.
Some plants, like cacti, contain water.
