they have no natural predators
you can use blasts of warm water to kill them but may affect wildlife in the same area, and you can intoduce a predator to kill them but really either way can harm other animals. really the only sate way is to remove them by hand.
Kiwi do not harm any other species except for the insects, larvae and other small animals on which they feeds.
No, not all symbiotic relationships involve harm. In mutualistic relationships, both species benefit from each other, while in commensalistic relationships, one species benefits without causing harm to the other. Harmful interactions can occur in some cases, such as in parasitic relationships where one species benefits at the expense of the other.
Each animal has a purpose in the environment called a niche or a job. Other than human beings, nothing harms the environment because it has a niche/job/purpose within the ecosystem. However, any animal can seriously harm the environment if its population gets too large. This usually only occurs when its predators have been eliminated (which is commonly done by humans).
There are over 50 different types of species of flying fish. Some of these species are harmful to other animals, fish, and insects. Other species of flying fish are nice to other animals and cause no strife or harm.
An organism that is carried into a new location by people is referred to as an "invasive species." These species can disrupt local ecosystems, outcompete native species for resources, and cause significant ecological and economic harm. Invasive species often thrive in their new environments due to a lack of natural predators or competitors. Examples include the zebra mussel and the Burmese python.
YES! ZEBRA MUSCLES ARE COMPLETLY EVIL! When you step on them in the water they sink into your foot with their sharp side up. last time i stepped on a zebra mussle it had to be removed from my foot and i was in the hospital for stiches. Lesson learned, never EVER swim where there are zebra mussles. :D
Humans ! We are destroying this planet at a scary rate - in complete disregard to the other species we share our home with !
Invasive species cause harm to the environment, because their like unknown organisms that exist, and replace original species. I might be able to change the environment/ecosystem.
Zebras do not typically kill their young. In rare cases, a zebra may reject or harm its offspring due to stress, illness, or other factors that disrupt the mother-infant bond.
all sponges are beneficial in the kingdom of porifera because sponges do not move and do not harm any other organisms
