Is Algae Plant Or Animal Give Reasons?

Do plants produce algae?

Plants, algae and cyanobacteria all conduct oxygenic photosynthesis 1,14.

That means they require carbon dioxide, water, and sunlight (solar energy is collected by chlorophyll A).

Photosynthesis uses water, carbon dioxide and sunlight to produce energy and oxygen..

What causes algae to grow?

Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. As more algae and plants grow, others die.

What type of animals eat algae?

Some of the known types of fish to eat algae are Blennies and Tangs, but along with fish there are snails, crabs, and sea urchins who also eat algae. These species are known to eat red slime algae, green film algae, hair algae, diatoms, cyanobacteria, brown film algae, detritus, and microalgae.

Is algae a plant or bacteria?

Algae are sometimes considered plants and sometimes considered “protists” (a grab-bag category of generally distantly related organisms that are grouped on the basis of not being animals, plants, fungi, bacteria, or archaeans).

Which type of plant is algae?

In general algae can be referred to as plant-like organisms that are usually photosynthetic and aguatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in moist situations on land.

How do animals interact with algae?

As “plants” the algae produce their own food and as “animals” they can eat other plants or even their own grazers. … For example, under nutrient (nitrogen and phosphorus) deficient conditions, mixotrophs can outcompete other algae species by eating them or utilizing the little available nutrients dissolved in the water.

Is algae a form of life?

Possible fossil examples have been found in rocks that are around 3500 million years old, in Western Australia. Although commonly referred to as blue-green algae, cyanobacteria are not actually algae. Cyanobacteria, and bacteria in general, are prokaryotic life forms.

Why is algae not a plant?

The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do not have roots, stems, or leaves. Some algae also differ from plants in being motile.

Is bacteria a plant or animal?

In answering the question, are bacteria animals or plants, we can deduce that bacteria are unique organisms and deserve their own separate classification system. Bacteria are neither animals nor plants.

Who eats algae in an ocean?

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.

Is algae a prokaryote?

By virtue of these characteristics, the general term “algae” includes prokaryotic organisms — cyanobacteria, also known as blue-green algae — as well as eukaryotic organisms (all other algal species). … (Prokaryotes include bacteria and archaea.

Is algae useless to humans?

The growth of algae is not useless pond scum, it is nothing short of an incredibly valuable resource to our planet and humanity. Why you ask? Algae can be effectively and efficiently converted into sustainable clean energy.
