There will be more first order which will eat more producers and third order consumers will have nothing to eat. Worms and Sea Slaters The animal chosen is brown snake. If the brown snake increased this will decrease the population of animals like, rats, mice, birds, lizards, and frogs. If the brown snake decreased this will affect its predators like the feral cat. An introduced species is animals brought into the country or into an ecosystem from another country or ecosystem. Biological control is a method of controlling pest’s (example, insects, mites, weeds and plant diseases) that relies of predation or other natural mechanisms.
