Take a bit of each other and burn it individually. If they make the same reaction, they are the same.
Next, take a bit of each other and put it into the water and stir it until it dissolves, then filter those dilutions. If there's something left, the substances are not clean.
If an ecosystem lost its producers, there would be no way for energy to move up the web and the ecosystem would most likely fail. Without these energy-capturing organisms, herbivores would get no energy or food. Without them, carnivores would get nothing as well. Because decomposers get energy from all three, they would also die out.
If only decomposers were removed, there would be a lack of nutrients in the soil for plants. This would result in the above (loss of energy, food, and other commodities).

Controls what substances can move in and out of the cell. it also protects the cell from its surroundings.
Answer:
Explanation:
Green crabs have chemoreceptors located on an <em>antenna</em>.
These are long segmented appendages near the crab´s eyes that have both chemoreceptors and allow them to feel the surroundings.
Crabs also have antennules, like short appendages close to the antennas that allow them to <em>sense</em> their environment. A crab can "taste" using hairs on their mouthparts, pincers and even its feet.
So they can detect the salinity of the water by "taste" using the antennules. If these antennules are bathed with nonsalty water, the information the crab´s brain receives is to increase the salinity of its body by the system explained above, increasing its rate of urine production.
