Oil spills especially harm wildlife around and in water, such as geese, ducks, fish, frogs, and swans. penguins, otters, and other such animals are harmed as well. The oil is very dangerous to the habitat as a whole, because if one part of a system is messed up, the whole system is effected. Oil spills are difficult to manage because oil is hard to clean up, and it spreads. Oil gets on everything and anything, and is toxic to living organisms. It can take off the natural oil on waterfowl's wings, making it hard to swim and escape the oil.
In communities where zebra mussels have invaded we observed that the population of invertebrates, zooplankton, and phytoplankton they will decrease when in open water. The population of bottom-dwelling invertebrates which are in the littoral zone will increase.
Hypothesis shows the zebra mussels will affect the fish negatively that feed on plankton in the open water but affect positively the fish which feed on invertebrates which are in the littoral zones.
The predictions by following the invasion of zebra muscles show that the number and growth rate of fish species in open water will decrease in population whereas the number and growth rate of fish species in the littoral zone will increase in population.
