1. Around 1900 the first dams were built on the Muskegon river, and this immediately cause a problem in the ecosystem by being a blockade for the movement of the water species, as well as causing higher mortality by killing them in the turbines.
2. By 1950 more dams were built, and the there were even more blockades on the way of the water species, so their movement was restricted even more, the mortality rates skyrocketed because of the disposing of the oxygen, temperature change, river flows changing etc.
3. Even though the scientists miss information from the period before the dams were built, since the information have started to be gathered it has been very obvious that the main factor for ruining the ecosystems on the Muskegon river are the dams by causing all sorts of changes in the water.
Answer:
"water, air, sunlight, soil, plants, microorganisms, insects and animals. Ecosystems may be terrestrial – that is, on land – or aquatic. Sizes of ecosystems vary; they could entail a small puddle or an enormous swath of desert. Likewise, natural ecosystems can look quite different from one another."
Explanation:
Answer:
Yes plants can do the respiration process by stomata
Answer:
The correct answer is E. A fault is best described as fractured rock that has been displaced.
Explanation:
Transforming faults are lithospheric plate limits where there is neither subduction nor creation of lithosphere. They are located on the edge of tectonic plates and cut the ridges perpendicularly. The borders near this type of fault are geologically active (earthquakes, volcanoes, etc.).
The most famous transforming fault is that of San Andreas. It is in fact a set of transforming faults which ensures the sliding of the Pacific plate against the North American plate.
Ummmm????? what does this question mean????
