It is true because if say if the predator the lizard dies out than the insects will reproduce to much and overflow the ecosystem they are in.
Yes
yes. they serve the function of "predators" in most ecosystems in which they exist.
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.
No, giraffes do not harm the Earth. No species in its proper ecosystem is harmful to the Earth as a whole. Rather, every species in its natural ecosystem helps to support the ecosystem. The only exception to that rule is humans.
eutrophication. This can lead to excessive growth of algae and other aquatic plants, which can deplete oxygen levels in the water. This depletion of oxygen can harm fish and other organisms, leading to a decline in biodiversity and, in some cases, the complete collapse of the ecosystem.
Yes
yes but some organisms can harm a ecosystem

Earthquakes generally have minimal effects on a freshwater ecosystem. Because fault lines do not tend to go through a freshwater ecosystem, the quakes cannot to harm directly to the organisms. Some damage that could be a result of a quake would be trees falling down, some organisms falling down and loosing their balance, ect. As you can see, it is not exactly a bad problems all the freshwater organisms have to worry about. And naturally, it would depend on where the ecosystem is. But overall, the earthquake really doesn't play a factor into the ecosystem as a whole.
harm
because they want to

Both, they harm them by taking them out of their natural habitat, but protect them from predators.
bacteria, predators, diseases, natural occurrences, and pollutants all may harm a crab.
yes because it harm us as well as ecosystem.
they have no natural predators
