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:
Environmental risk can be managed by a number of strategies. The first employed is to prevent pollution at its source because this strategy eliminates the need to dispose of waste, restore habitats, or remediate contamination. In situations where pollution prevention is not possible or practical, then other strategies become important. Minimizing the amount of waste generated and properly disposing of the waste that is generated is one strategy, as is avoiding habitat damage.

Answer:
global distribution of megacities refers to the dispersion of a population of 10 million people or more in all parts of the world.
Explanation:
Global distribution of megacities is usually determined by the number of people within a population which should not go below 10 million. these people making up the populations can be located in different locations, either in the cities or in the countryside. In January 2015, for example, China’s Pearl River Delta conurbation overtook Tokyo as the world’s largest city (Van Mead, 2016). However, this depends on how the ‘city’ is measured – the Pearl River Delta includes the cities of Shenzhen, Guangzhou, Foshan and Dongguan (but not Hong Kong, which is considered a separate territory under its ‘Special Administrative Zone’ status within China). If these cities were measured separately, Tokyo would likely remain the world’s largest city.
The Grand Canyon is like a history book because you can see all the layers of rock and dirt throughout the ages, and scientists can read those to tell what happened.
Hope this helped :)
