Question

What causes algae?

Answer 1

Algae can be found in a variety of environments, including oceans, rivers, and lakes, as well as ponds, brackish water, and even snow. Algae are typically green, but they can also be found in a variety of other colors. Algae living in snow, for example, contain carotenoid pigments in addition to chlorophyll, giving the surrounding snow.

Complete answer:
“Algae is a broad and incredibly diverse group of eukaryotic, photosynthetic life forms. Because these organisms do not share a common ancestor, they are not related to one another (polyphyletic).” Algae with multiple cells include giant kelp and brown algae. Diatoms, Euglenophyta, and Dinoflagellates are examples of unicellular organisms.

Because most algae require a moist or watery environment, they are common near or inside bodies of water. They are anatomically similar to another major group of photosynthetic organisms – land plants. However, the similarities end there because algae lack many structural components found in plants, such as true stems, shoots, and leaves. They do not, also, possess vascular tissues to circulating essential nutrients and water throughout their body.

When the concentration of dissolved oxygen in the water is low (anoxic), sediments release phosphate into the water column. This phenomenon promotes algae growth. Early blue–green algal blooms typically appear in the spring, when water temperatures are higher and there is more light.

Algal blooms are most likely the result of a combination of environmental factors such as available nutrients, temperature, sunlight, ecosystem disturbance (stable/mixing conditions, turbidity), hydrology (river flow and water storage levels), and water chemistry (pH, conductivity, salinity, carbon availability).

Note: Algae grows as a result of an imbalance in the ecosystem of your pond. When there are too many nutrients in your water garden due to decomposing plant material, fish waste, or other debris buildups, algae will flourish because the nutrients act as a fertilizer.
