Answer:
-People's activities can improve the health of an ecosystem.
-Plants produce food for ecosystems.
-Predators keep ecosystems healthy.
Explanation:
-People can have significant impacts on ecosystems, and while human influence is typically thought of as destructive, we can also help keep an ecosystem healthy by not disrupting natural patterns.
-Plants produce food for many consumers in an ecosystem and are a source of food for large numbers of organisms that exclusively consume plantes.
-Predators are healthy for an ecosystem because they prevent the overpopulation of any one species.
Answer:
1- Option (D)
2- Option (C)
Explanation:
The rocks of oceanic crust are created by spending a huge amount of time in a water-rich environment. During the subduction process, the plates at greater depth are comprised of rocks that contain water in them. As this water reaches the mantle, the conditions of pressure and temperature forces these hydrated rocks to remove the water from them. This water then mixes up with the mantle and thereby reduces the melting point of the mantle rocks. This results in the formation of magma. These magma being lighter eventually rises upward that eventually leads to the formation of the volcanoes. This process of melting is known as the hydration-induced melting.
Thus, the hydration-induced melting process is responsible for the formation of volcanoes on the overriding plates.
Hence, the correct answers are mentioned above.
Domes in early central plan churches were used to give the attendants the urge to look up, which symbolized looking up to God.
