Will algae die without artificial light?
Asked in Protists
Why does blepharisma disintegrate and die if exposed to intense artificial light?
Asked in Animal Life
Why is light necessary for the survival of the green algae and the animals in the ecosphere?
How might algae growth near the surface of a pond affect living organisms living in the pond?
Asked in Lakes and Rivers
Excess fertilizers from fields that wash into rivers and streams can cause algae to overgrow. What is the main problem of this?
Asked in Farm Crops
What will happen when too much fertilizer is added to soil planted with crops?
Eutrophication occurs: Fertilisers (very soluble) are easily leached out of the soil, so when it's washed in the water, the algae absorb the fertilisers and it grows rapidly. It forms a blanket on the surface of the water, blocking light from the underneath algae. The underneath algea die without light, then the bacteria decomposes the dead algae, using up oxygen in water for respiration. Finally, the animals in water die through lack of oxygen... RE.WAS~
Is some algae necessary in a healthy pond?
Why do plants grown in artificial light rot?
Asked in Water Fountains and Ponds
How does a thick layer of algae growing on the surface of a pond affect the lives of other organisms living in the pond?
The answer is that the algae will block the sunlight and can cause some living animals in the pond die. Also, bacteria will grow, break down everything in the pond, but not the algae, and will get in the oxygen in the water. Fishes and other organisms in the water die without fresh oxygen. About the only life that survives is the algae on the surface.

What do most plants prefer fake light or sunlight?
Does algae decay and consume oxygen when they die?
Asked in Science
Do crystals grow taller in the dark or the light?
Depends upon what type of mineral is crystallizing. For some types of minerals (aragonite in particular), their growth is mediated by photosynthetic algae. Obviously, they would grow faster when exposed to light. Otherwise, the algae die and the crystals are left to grow inorganically, which may mean not at all.
Asked in Science
What causes algae to die?
Lack of sunlight or nutrients. Algae is essentially a type of plant. Think about typical household plants, if they don't have water, soil, or sunlight, they will die. But algae, unlike household plants, typically live in a body of water, so a lack of water normally is not a cause of death for them. Normally, algae die because there is not enough sunlight or nutrients, possibly because of an algae bloom (too much algae that use up sunlight and nutrients).
