Explanation:
you have to keep heat and pressure rising on the rock, until the minerals melt. The earlier stages of this process (if it ends at that point) are called 'migmatite' (mixed rock) where the rock consists partially of unmelted metamorphic rock
The air in Greg's house is like the cytoplasm of a cell because it is the gel-like material that surrounds the other parts of the cell.
Hope this helps! :)
Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.
