What is classification of algae?
Algae are classified into three classes. They are Chlorophyceae, Phaeophyceae and Rhodophyceae.
What are algae and how are they classified?
The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. Recently they are classified in the kingdom of protiste, which comprise a variety of unicellular and some simple multinuclear and multicellular eukaryotic organisms that have cells with a membrane-bound nucleus.

What is algae Class 8?
Algae are simple plant- like organisms which are usually aquatic in nature. They contain a cell wall and chlorophyll and can make their own food by photosynthesis. Algae can be unicellular or multicellular. Some of the common examples are diatoms, chlamydomonas, and seaweed.
What are the 5 types of algae?
Different forms of algae:
- Green algae (Chlorophyta)
- Euglenophyta (Euglenoids)
- Golden-brown algae and Diatoms (Chrysophyta)
- Fire algae (Pyrrophyta)
- Red algae (Rhodophyta)
- Yellow-green algae (Xanthophyta)
- Brown algae (Paeophyta)
Is algae a decomposer?
Decomposers consume organic materials from dead plants and animals, break them down chemically into simpler molecules and return the molecules to the environment. Plants and other producers such as algae use these nutrients, which include carbon, nitrogen and minerals.
Is algae a Saprotroph?
(iv) Plants utilize the carbon dioxide dissolved in the water absorbed by the root for photosynthesis. (v) The sun is the ultimate source of energy for all living organisms. (vi) Algae are saprotrophs. (viii) Saprotrophs take their food in solution form from dead and decaying matter.
Is algae a Heterotroph?
In other words, most algae are autotrophs or more specifically, photoautotrophs (reflecting their use of light energy to generate nutrients). However, there exist certain algal species that need to obtain their nutrition solely from outside sources; that is, they are heterotrophic.
Is a bacteria Decomposer?
Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.
What are 4 types of decomposers?
Bacteria, fungi, millipedes, slugs, woodlice, and worms represent different kinds of decomposers. Scavengers find dead plants and animals and eat them.
What are 10 examples of decomposers?
Examples of Decomposers in Terrestrial Ecosystems
- Beetle: type of shredder that eats and digests detritus.
- Earthworm: type of shredder that eats and digests detritus.
- Millipede: type of shredder that eats and digests detritus.
- Mushroom: type of fungi that grows out of the ground or the dead material it’s feeding off.
What are 3 examples of decomposers?
Examples of decomposers include bacteria, fungi, some insects, and snails, which means they are not always microscopic. Fungi, such as the Winter Fungus, eat dead tree trunks. Decomposers can break down dead things, but they can also feast on decaying flesh while it’s still on a living organism.
What are 2 examples of decomposers?
A decomposer is an organism that breaks down organic materials from dead organisms to obtain energy. These organisms are basically living recycling plants. Fungi, worms, and bacteria are all examples. The dead stuff they eat is called detritus, which means “garbage”.
What are 5 decomposers?
Examples of decomposers include organisms like bacteria, mushrooms, mold, (and if you include detritivores) worms, and springtails.
What kinds of bacteria are decomposers?
Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria. Additions of these bacteria have not been proved to accelerate formation of compost or humus in soil. Rhizobium bacteria can be inoculated onto legume seeds to fix nitrogen in the soil.
Is bacteria a Decomposer or producer?
Green plants are producers who make food in their leaves. A decomposer is a living thing that gets energy by breaking down dead plants and animals, Fungi and bacteria are the most common decomposers.
Are fungi bacteria?
How fungi makes us sick. Fungi are more complicated organisms than viruses and bacteria—they are “eukaryotes,” which means they have cells. Of the three pathogens, fungi are most similar to animals in their structure.
Why is bacteria a decomposer?
Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting.
What is the function of decomposers?
Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth.
How do decomposers die?
When these organisms die, the carbon remains locked in their bodies. Decomposers are able to break down this material and release carbon back into the atmosphere and the cycle can begin again. Without decomposers, the carbon would remain locked in dead organisms and could only be released through combustion.
Is a snail a decomposer?
Both shelled snails and slugs can generally be categorized as decomposers, though they play only a small role compared to other decomposition organisms. Because shelled land snails have a high calcium demand, they are sensitive to calcium availability due to soils and plants.
Is a spider a decomposer?
Decomposers are organisms that break down dead organic matter. Macroinvertebrates are small organisms that we can see with our “naked” eye and that do not have a backbone, unlike vertebrates, which do. Examples of terrestrial macroinvertebrates that you might find include snails, worms, ants, and spiders.
Is a cockroach a decomposer?
Cockroaches love waste. In the wild, they are important decomposers, eating away at any plant or animal remains they can find.
What is a snail’s purpose?
Slugs and snails are very important. They provide food for all sorts of mammals, birds, slow worms, earthworms, insects and they are part of the natural balance. Upset that balance by removing them and we can do a lot of harm. Thrushes in particular thrive on them!
Are snails good or bad?
There’s no doubt that slugs and snails help to clean up garden debris. Almost all common garden snails and slugs (except the uniquely destructive Field Slug Deroceras reticulatum), prefer dead garden detritus to living plants. Their feces make a nitrogen-rich, mineral-laden fertilizer that enhances plant nutrition.
Does salt kill slugs?
Many people suggest controlling slugs with salt. But salt will kill them, rather than simply control them. Making a direct slug kill using salt will draw out the water from a slug’s moist body, resulting in death by dehydration.
Do snails have brains?
A snail breaks up its food using the radula inside its mouth. The cerebral ganglia of the snail form a primitive brain which is divided into four sections. This structure is very much simpler than the brains of mammals, reptiles and birds, but nonetheless, snails are capable of associative learning.
