What is El Niño?

Biology
1 answer:
Anastasy [175]3 years ago
5 0

El Niño: an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.

La Niña: a cooling of the water in the equatorial Pacific, which occurs at irregular intervals, and is associated with widespread changes in weather patterns complementary to those of El Niño, but less extensive and damaging in their effects.

how they differ: La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate. ... Typically, El Niño occurs more frequently than La Niña.

zhenek [66]

Answer:

Since the nature of pollutants is not mentioned in the question, several speculations can be made here.

  1. Pollutants can affect the photosynthesis: Some pollutants are toxic to plant metabolic reactions such as photosynthesis. This is because of their oxidative nature that can damage the photosystems. This ultimately impairs the plant functioning, e.g. ozone in the air.
  2. Pollutants can affect the plant-associated microbial communities: Some pollutants such as antibiotics can target plant-associated bacterial communities that are required for plant health. Just like the human gut, plants also have beneficial bacteria that live inside the plant tissues. These bacteria are called endophytes. The harmful nature of the compounds can affect those bacteria which decreases plant fitness.
  3. Pollutants can compete with nutrients that act as limiting factors: Some pollutants are hydrophobic in nature and make the beneficial nutrients less available to the plants. Likewise, some pollutants reduce the bioavailability of plant necessary nutrients directly. This results in reduced growth and development in plants.
  4. Pollutants can cause physical damages to plant tissues: Some pollutants are highly reactive in nature and can cause physical damages to the plants. This will result in the attack of pathogens at the wound site which can later take control of host metabolic machinery at later stages. Resultantly, plant fitness is decreased and in some cases, it dies off completely.

It is important to consider that some pollutants are taken up easily by plants whereas other pollutants are difficult. This is because of their water solubility criteria. If a pollutant can be taken up by plant directly, it can cause more damages to the plant as compared to the pollutant which interacts from outside.

The growth of mosses and lichens on a bare volcanic region helps prepare the area for the next stages of succession. How do moss
melamori03 [73]

Answer:

The correct answer is - B. they build up soil deposits on the rocky ground.

Explanation:

Lichens and mosses are known as the pioneer species as they prepare the particular region for the next stages of succession on the bare volcanic region. Lichens and mosses grow on the bare rocks and secrete acids to break the rocks and start soil production.

The soil deposits produced by breaking the volcanic rocks by secreting acids from mosses and lichens. Even after dying these species leads to thickening of the soil and increase organic matter for the next stages to grow.
