What is algae and its function?

INTRODUCTION. Algae play many important and beneficial roles in freshwater environments. They produce oxygen and consume carbon dioxide, act as the base for the aquatic food chain, remove nutrients and pollutants from water, and stabilize sediments.

What is an algae answer?

Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes.

What are algae easy definition?

What is the function of green algae?

Green algae are food for sea animals and humans. Green algae are used in cancer treatment. They could help reduce carbon dioxide in the atmosphere.

What is algae Class 7 short?

The green, slimy patches that grows in moist areas or stagnant water is called algae. The presence of chlorophyll in algae makes them capable to prepare their own food by process called photosynthesis.

What is algae Class 8?

What is chlorophyta used for?

The chlorophytes, because of their photosynthetic activity, made them one of the most important producers in the ecosystem. They are a major source of starch and oxygen as a byproduct of photosynthesis. They serve as food for many heterotrophs. Many of them form symbiotic relationship with other groups of organisms.

What is algae Ncert?

Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic (both fresh water and marine) organisms. They occur in a variety of other habitats: moist stones, soils and wood. Some of them also occur in association with fungi (lichen) and animals (e.g., on sloth bear).

Is algae helpful or harmful to humans?

Most algae are harmless and an important part of the natural ecosystem. Some types of algae produce toxins that can be harmful to people and animals. Where these harmful algae grow rapidly and accumulate in a water environment, it is known as a harmful algal bloom.

Is eating algae bad for You?

Answer: Algae is only harmful to plants when it starts getting bad, a little algae is not harmful. Algae grows where light & water are in the same place.

What does algae provide animals with?

In addition to making oxygen , algae are important for other reasons. Water animals such as whales, seals, fish, octopuses, and starfish depend on algae for food. People also eat some types of algae. In many parts of the world farmers use seaweeds as fertilizer (a material to help crops grow).
