It could make food but not break it down
If one trophic levels population increases or decreases too much, it can decrease the amount of producers, this decreasing the amount of energy available in food web which can cause population crash.
The situation that is most similar in which a plant is moved to a higher concentration of salt in water is that of a freshwater plant being put into sea water.
Due to too much salt concentration, freshwater plants cannot survive on the ocean. If you ever see a plant wilting and am sure that this is because of soil imbalance, this can be solved by adding more water to even out the concentration.
<span>This is true. Pioneer species are introduced to infertile soil so that the soil may become suitable for growing other plant species. These species do not rely heavily on soil; instead, they live on rocks and minerals. Moreover, they break down these rocks into soil so and eventually create a thicker layer of soil, allowing other plant species to inhabit the same region.</span>
Answer:
The most abundant gas in the atmosphere is nitrogen, with oxygen second, and argon as third.
Explanation:
The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. The gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Usually, the 4 most abundant gases are:
Nitrogen (N2) - 78.084%
Oxygen (O2) - 20.9476%
Argon (Ar) - 0.934%
Carbon dioxide (CO2) 0.0314%
