Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.
Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.
On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.
Answer:
<em>Like every other organism the population size of the humans have increased over time.</em>
Explanation:
With the improvements in science and technology, life becomes better and better for human beings. In the past, when there were no discoveries for curing diseases, the human population declined because of the spread of various diseases and famine conditions.
But as the developments in the scientific world are made, it has been easier to cure diseases and other problems. As a result, the population size of the human goes on increasing.
This rock can be classified as:
an igneous rock.
Igneous rocks are made up of
randomly arranged interlocking crystals and the important minerals that can be
found in igneous rocks are feldspars, quartz, olivines, pyroxenes, amphiboles,
and mafic minerals. All of these minerals are important in the formation of
almost all igneous rocks, and they are basic to their classification.
<span>Substances can move into and out of cells through the cell membrane. The three main types of movement are diffusion, osmosis and active transport.</span>
The chemical reactions in the cell would not happen as fast and would require more energy to catalyze the reaction between the two reactants.

Chemistry/ Example: Take breathing for example, when you breath you breath out carbon dioxide. The CO2 can't just leave like that and only 10% binds to hemoglobin. The rest turns into carbonic acid in your blood and its plasma. However, the acid is unstable, so it turns into bicarbonate and a dissociated proton (H). You have carbonic anhydrase that converts the two so you can breath out CO2; the carbonic acid separates into H2O and CO2. This process would take a LONG time without the enzyme-- CO2 build up, even minimal amounts it lethal.
