Pumping water out of the ground faster than it is replenished over the long-term causes similar problems. The volume of groundwater in storage is decreasing in many areas of the United States in response to pumping. Groundwater depletion is primarily caused by sustained groundwater pumping.

Brut [27]

Answer:

Although the question is incomplete, missing options are

  • In 1997, they reduced their water consumption.
  • In 1996, they planted more trees to curb water pollution.
  • In 1994, they used only bottled water for drinking purpose.
  • In 1995, they complained about foul odor and taste in water.

Correct option: <em><u>In 1996, they planted more trees to curb water pollution. </u></em>

Explanation:

Among given options, a clear trend of nitrate level can be seen. <u>Initially, the nitrate level increased in water in first two years (1994 and 1995) and then it decreased significantly</u>.

From the conditions given in the question, the most probable answer is B the plantation effect (<u>phytoremediation</u>). During phytoremediation, <u>plants take up nutrients including nitrate</u> from the water via roots. This nitrogen is then used for the growth and development of plant body mass (e.g. amino acids). As more plants were growing in later years, higher reduction of nitrate was seen. Resultantly, in 1997, the concentration of nitrate was dropped to 7.3 mg/L.

The other options are not correct due to following reasons.

A. There is no information on water consumption in the question

C. There is no information on people's behavior on drinking water lifestyle.

D. Nitrate in the water cannot be smelled or tasted.

Which of the following illustrates intraspecific competition? A sea gull swooping down to snatch a fish from the water's surface
choli [55]

Answer: Male red-winkled black birds defending limited nesting sites from other males.

Explanation: Intraspecific competition is defined as a competition between two individuals from the same species. There are two types of intraspecific competition which are interference intraspecific competition and exploitation intraspecific competition. For the purpose of the answer provided above, interference intraspecific competition is discussed.

In interference intraspecific competition, the species establish hierarchies through aggressive behavior in which one or more individuals within the population holds a dominant status over the others. These individuals limit or prevent access of more subordinate individuals to a resources through direct interactions.

Here, only those individuals who are dominant or holds territories will increase their production success. Example of this is in when two winkled black birds establishes a territory of nesting sites, thus limits the access of this nesting sites thereby defending the nesting sites from other males.
