during the downpour in a village,the rainwater carried away excess of nitrogenous and other compounds present in the soil to a pond.how will they affect the growth of algae and phyloplankton in the pond?
the excess of nitrogenous and other compounds present in the soil effect the growth of algae and phytoplankton in a pond.due to excess of nitrogenous and other compounds the organisms consume them and become healthy.when the number of algae and phytoplakton increase in the pond. then they compete with each other for the nutrients.this effect the growth of these organisms.they both compete and no one get proper nutrient or diet for their growth.
The excess of nitrogenous and other compounds carried by rainwater from the soil to the pond can impact the growth of algae and phytoplankton in several ways. Typically, nitrogen and phosphorous are the primary nutrients that promote the growth of these organisms. However, an excessive amount of these nutrients can cause an overgrowth of algae and phytoplankton, leading to an event known as eutrophication. Here's how it happens:
1. Nitrogenous compounds, such as nitrate and ammonia, are essential nutrients for the growth of algae and phytoplankton. When these compounds enter the pond, they act as fertilizers, promoting the growth of these organisms.
2. As the algae and phytoplankton populations increase, they consume more oxygen during photosynthesis. This can lead to a decrease in oxygen levels in the pond, causing a condition called hypoxia or even anoxia (no oxygen), which is harmful to aquatic life.
3. The rapid growth and accumulation of algae and phytoplankton can create dense algal blooms. These blooms can block sunlight from penetrating the water column, reducing light availability to deeper water levels. This reduction in light quality limits the growth of submerged aquatic plants, affecting the overall biodiversity of the pond.
4. When the algae and phytoplankton population eventually die off or decay, bacteria and other microorganisms decompose them. During this decomposition process, oxygen in the pond is further depleted, worsening the hypoxic conditions.
5. The decreased oxygen levels, combined with the accumulation of decomposing organic matter, create unfavorable conditions for many other aquatic organisms, such as fish and invertebrates, leading to a decline in their populations.
Therefore, the excess nitrogenous and other compounds carried by rainwater from the soil to the pond can disrupt the ecological balance of the pond, favoring the growth of algae and phytoplankton to an excessive extent. This, in turn, can lead to decreased oxygen levels, reduced biodiversity, and negative impacts on other aquatic organisms.
