Fertilizers have nutrients that plants grow. sometimes, when it rains, fertilizers are washed away from farmland into ponds and lakes. this promotes the growth of algae, a type of plant, present in the water. it is observed that algae grow very fast and cover the surface of the pond completely. they use up all the dissolved oxygen in the pond. how does this affect the other organisms in the pond

They do not get enough oxygen, and die.

Explanation:

When fertilizer flows into rivers and lakes, they trigger the process of eutrophication, which is the increased concentration of nutrients in the water environment. This high concentration of nutrients encourages the overproduction of algae that often completely covers the surface of the aquatic environment.

The large amount of nutrients, also increased by the death of these algae, helps in reproduction and exaggerated increase of aerobic bacteria. By using oxygen in their breathing, these bacteria end up consuming a large amount of this gas, which causes the death of several other species, such as fish and other aquatic beings. It is noteworthy that, with the lack of oxygen, aerobic bacteria also end up dying.

In addition, excessive algae build-up forms a layer that prevents sunlight from passing through, which consequently affects the photosynthesis process performed by algae and aquatic plants. This causes the death of photosynthetic organisms that are not located in the most superficial layers.

answer; the above answer to the above statement is (true)

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
