Which of the following are 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.

Which of the following are freshwater ecosystems?

The habitats that freshwater ecosystems provide consist of lakes, rivers, ponds, wetlands, streams, and springs.

Which of the following are the main decomposers in ecosystems?

Bacteria and fungi, collectively called decomposers, carry out the breakdown (decomposition) of plants and animals and their organic compounds. Hence, the main decomposers in an ecosystem are- Fungi, Insects and Prokaryotes.

Which of the following kingdoms has plant decomposers?

So, the correct answer is ‘Monera and Fungi’

Which one of the following symmetries is found in adult sea anemone?

When the body can be divided into two similar halves by one or two vertical planes only, the radial symmetry is called biradial symmetry, it is present in the sea anemone.

Why do sea anemones have biradial symmetry?

Sea anemones are animals with this body plan. Biradial symmetry is when the organism can be divided up into equal parts, but only in two planes. It is different than radial symmetry, because two planes divide the organism, but not more than two.

Are sea anemones secondary consumers?

These very high rates suggest that anemones are major secondary consumers in rocky intertidal communities in the south-western Cape.

Are all carnivores top predators?

The animals that eat secondary consumers, like owls that eat rodents, are known as tertiary consumers. Carnivores that have no natural predators are known as apex predators; they occupy the top of the food chain. Not all carnivores are predators.

Are anemones carnivores?

Anemones are carnivorous, feeding on tiny plankton or fish. Their stinging tentacles are triggered by the slightest touch, firing a harpoon-like filament called a nematocyst into their prey. Once injected with the paralyzing neurotoxin, the prey is guided into the mouth by the tentacles.

Are cnidarians filter feeders?

Cnidarians are filter feeders. 5. Pores in sponges are called Ostia or porocytes.

Are cnidarians radial symmetric?

Another important characteristic of some cnidarians is that they have bodies with nearly radial symmetry.

Are corals producers or consumers?

Both a primary consumer and primary producer! Coral has a mutually beneficial relationship with microscopic algae which means it gets energy from photosynthesis during the day.

Are filter feeders predators?

As opposed to predators who seek out specialized food items, filter feeding is simply opening up your mouth and taking in whatever happens to be there, while filtering out the undesirable parts.

Are sea anemones heterotrophs?

Because they belong to the animal kingdom, you can also assume that all cnidarians are multicellular and heterotrophic – meaning they must consume their food in some way.

Are zooxanthellae plants or animals?

Zooxanthellae are single-celled plants that live in the tissues of animals. They are dinoflagellates, a group of microscopic plants which are usually found swimming and floating in the sea.

Can cnidarians reproduce asexually?

Cnidarians reproduce both sexually and asexually. Some species can produce both eggs and sperm in the same organism. These organisms are called simultaneous hermaphrodites and release gametes into the ocean in egg-sperm bundles. Some species are also either male or female and produce either eggs or sperm.

Can different anemones touch each other?

They can, and I think would, move if they were being injured by being too close to another anemone.

Can rock flower anemones touch each other?

Rock flower anemones are not known to sting each other and can live in a rock flower anemone pack. However, these anemones can display aggressive behavior towards anemones of other species of corals.

Do cnidarians display radial or bilateral anatomical symmetry?

Even though cnidarians vary a great deal, they all have radial symmetry as a common characteristic. The images below show how a sea anemone and jellyfish have radial symmetry, while a lobster has bilateral symmetry.

Do cnidarians have a circulatory system?

Cnidarians lack organs. This means that they do not have respiratory or circulatory systems. Like the cells in sponges, the cells in cnidarians get oxygen directly from the water surrounding them.

Do earthworms have a complete digestive system?

Earthworms have a complete digestive system, one which has two openings, the mouth and the anus.
