Forests capture and store water and can play an important role in providing drinking water for millions of people in cities,villages and towns.Forest contribute to the reduction of water-related problems like floods by absorbing water through their roots and storing it in the ground.
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:
Water
Explanation:
Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.
In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.
Nations of the world can work together to use energy more efficiently.
One important influence is climate ie many Canadians, especially from the cold Prairies like to move to Vancouver, BC because the climate is so much milder in the winter due to the proximity of the Pacific Ocean. Another important influence is topography, so that if a country is mostly mountainous, the cost of road building will be more expensive than on, say the prairies or on the coastal desert of Peru and northern Chile. Another important influence of geography is the presence of fertile soil such as in El Salvador from the ash of the volcanoes to grow coffee in, or the fertile floodplain of the Nile River in Egypt.
