Answer:
Alaska Volcano
Observatory has issued warnings stating that either or both could erupt in the weeks or months ahead, sending ash plumes into the atmosphere and possibly disrupting air traffic between Asia and North America.
Europe and America used slaves for labor so the slaves in America or Europe are subtracted from the South African population.
Answer: 3/4
Explanation: 0.75 as a fraction is 3/4.
Hope I helped :)
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:
No, I don’t agree that there are enough resources on earth to support increase in per capita consumption rates if human population growth rates stay the same.
Explanation:
- The population is growing at a much higher rate than we expect it to be. According to statistics, in recent years we've been adding about a billion people every 12 or 13 years or so.
- There are no any resource which lasts eternity, so we must use it very wisely.
- And we all know the consequences of the increasing population. The resources are limited and population is excessive so with this rate of growth of population and limited resources, we are the guest for few decades only.
