High content of phosphate ion in river Yamuna may lead to:a)decreased...
The phosphate ions promote the growth of algae in water
More the algae present, more the surface area of the waterbody covered and oxygen cannot penetrate into the depth of the water, it is utilized by the algae
As a result, there will be an increased growth of algae and decrease in dissolved oxygen
This is known an eutrophication.

High content of phosphate ion in river Yamuna may lead to:a)decreased...
High content of phosphate ion in river Yamuna may lead to:

Phosphates are essential nutrients for plants and algae. However, when there is an excessive amount of phosphate present in water bodies such as the river Yamuna, it can have significant negative impacts on the ecosystem.

1. Decreased level of dissolved oxygen:
- The high phosphate content in the water promotes the growth of algae, leading to algal blooms.
- Algal blooms can cover the surface of the water, blocking sunlight from reaching the submerged aquatic plants.
- Without sunlight, the plants cannot photosynthesize and produce oxygen, resulting in a decreased level of dissolved oxygen in the water.
- Additionally, as the algae die and decompose, the process consumes oxygen, further depleting the dissolved oxygen levels in the water.

2. Increased growth of algae:
- Phosphates act as a nutrient for algae, promoting their growth.
- Excessive phosphates in the water can cause an overgrowth of algae, resulting in algal blooms.
- These blooms can lead to the formation of green mats on the water surface, which may disrupt the natural balance of the ecosystem.
- The increased growth of algae can also lead to the depletion of other nutrients and resources in the water, negatively affecting other aquatic organisms.

Overall impact:
The combination of decreased dissolved oxygen levels and increased growth of algae can have severe consequences for the river Yamuna ecosystem:
- Fish and other aquatic organisms may struggle to survive in water with low oxygen levels, leading to a decline in their populations.
- The excessive growth of algae can block sunlight, preventing the growth of submerged aquatic plants and disrupting the food chain.
- Algal blooms can also release toxins into the water, affecting the health of organisms and reducing biodiversity.

Therefore, the high content of phosphate ions in the river Yamuna can have a detrimental impact on the dissolved oxygen levels and promote the growth of algae, ultimately disrupting the entire ecosystem.

Read the given passage and answer the questions:Metallic Character: The ability of an atom to donate electrons and form positive ions (cation) is known as electro-positivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electropositivity decreases due to decrease in atomic size. Non-Metallic Character: The ability of an atom to accept electrons to form a negative ion (anion) is called non-metallic character or electronegativity. The elements having high electro-negativity have a higher tendency to gain electrons and form anion. Down the group, electronegativity decreases due to increase in atomic size and across the period, from left to right electro -negativity increases due to decrease in atomic size.Identify the reason for the gradual change in electronegativity in halogens down the group.
