Answer:e
Explanation:
1. Acids react with metals to release hydrogen gas
Take some granules of zinc in one glass test tube and magnesium in another glass test tube and magnesium in another glass test tube. Pour dilute hydrochloric acid in one and sulphuric acid in the second. Reaction takes place and a gas is released in each. Test the gas for hydrogen by bringing a bur…
2. Acid reacts with a base (metallic oxide) to form salt and water
HCl + ZnO → ZnCl2 + H2O Acid reacts with an alkali (hydroxide) to form salt and water. HCl + NaOH → NaCl + H2O In these Reactions acid neutralizes the base to form neutral substances like salt and water.
3. Acids reacting with Metals
The reactions of dilute acids with a variety of different metals can be investigated, small fresh samples of metals are placed in 2ml samples of dilute hydrochloric or sulfuric acid. The rate of reaction depends on the 1. Concentration of the acid – if the acid is too dilute the reaction is very slow. 2. Type of metal
C) If we spray insecticide, only those who are resistant to the insecticide will survive.
That is what the bottleneck effect entails - a sharp reduction in the population and the survival of only a few.
Answer:
Primary producers (autotroph organism), primary consumers (herbivores), secondary consumers (carnivores), decomposers
Explanation:
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
When one of the links disappears, it affects the superior links as they will not have their food source. The immediately anterior link will be beneficiated, as it will not be eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link.
