Answer:
The correct answer is <em>c. animal wastes and fertilizers. </em>
Explanation:
Two major sources of nitrate pollution are farming and breeding activities. There are also certain industrial activities involved in nitrate pollution, but in general, these industries are related to agriculture.
The indiscriminate use of fertilizers for several years in intensive productions produce high nitrate concentration in soil and consequently elevate the risk of nitrate lixiviation.
Breeding animals produce nitrate pollution by their wastes, which accumulate and are not treated. These wastes include flesh, hair, feathers, skin, fat, liquids, excrements, among others. These wastes are an important source of nitrate.
In many cases, animal wastes are used by farmers as organic matter to improve their production. But excessive and incorrect use of it might produce severe damage in water sources.
Base on one of the Law of Thermodynamics, the amount of available energy decreases whenever energy is changed in form (which includes a transfer from one trophic level to another). So, as we go from the first trophic level to the top trophic level, the amount of available energy becomes less and less.
Fossil Fuels and Continental drift support the idea that once continents were together.
Explanation:
- Fossil fuels like plants, animals and rocks are of the identical features were found in the two different continents. For example, identical rocks found in the two sides of the Atlantic ocean, even the mountains in two different continents formed of the identical rocks.
- The next one is fossils of the seed fern Glossopteris is found across all the southern continents. Hence, there is continental drift happened which caused the separation of continents.
