1. A) carnivore; third
The trophic levels are divided by the manner in which the energy is produced and consumed among the living organisms. The first trophic level is occupied by the autotrophs, which are the organisms that are able to produce their own food. The second trophic level is occupied by the organisms that feed upon the autotrophs, thus they are the herbivores, as well as the omnivores in partial sense. In this case we will have the ants at the second level. The third trophic level is reserved for the organisms that feed upon the organisms of the second trophic level, thus they are predators. In this case, we will have the wasp in the third trophic level.
2. B) consumption; 20
If there are herbivores and plants, the plants account for 1,000 kg in biomass, and the herbivores eat 200 kg of them, then the consumption is 20% of the total biomass. This kind of a scenario is able to support the whole population of herbivores without any problem, as there is much more food than they need. It will only become a problem if the population of herbivores starts to grow exponentially, and they start to consume all of the food and even require more, the population will collapse.
3. C) N20
The processes and nitrification and denitrification are very common, both in nature, and because of the human activity. The human activity has actually increased this process significantly. The main product of the nitrification-denitrification is the N2O. It is a vital product for the nitrogen cycle, and it is one that is increasing the atmospheric temperature, thus too much of it is not of best interest for anyone.
Answer:
Russia has built the Trans-Siberian Railroad to overcome the Friction of Space.
Explanation:
Russia is the largest country in the world, and on top of it, its territory is stretched by longitude which creates a situation where from the easternmost to westernmost point the distance is incredibly big. As both the eastern and western coasts are strategically very important for Russia, it is crucial that they are connected with infrastructure that will enable relatively fast and cheap transportation and traveling.
The solution came in the form of the Trans-Siberian Railroad. This is the longest railroad in the world, starting from Saint Petersburg, diverging into two lines, one going to Tyumen but before that at Yekaterinburg turning to merge with the other line at Chelyabinsk, continuing to Chita where it diverges again with one line going through Khabarovsk to Vladivostok while the other moving slightly through Mongolia, Harbin in China, and ending in Vladivostok.
