What are decomposers class 7?

Answer: Decomposers are organisms that act on dead plants and animals, and convert them into a dark colored substance called humus. Bacteria and some fungi act as decomposers. They play a key role in releasing the nutrients present in dead plants and animals into the soil.

What are decomposers class 9?

Answer: Decomposers are micro-organisms that digest things that are dead or decaying and turn the dead plants and animals into humus.

What are decomposers answer?

Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi.

What are decomposers class 10th?

Hint: Decomposers are the organisms that decompose the dead organisms and break down the complex compounds of dead organisms into simple nutrients. They play a very important role as they decompose the complex compounds (dead organisms) into simple components.

What are decomposers examples?

The micro-organisms that decompose/ convert the dead remains of plants and animals to humus are called decomposers. The two common examples of decomposers are bacteria and fungi.

What are decomposers for class 6?

Decomposers are organisms that feed on dead plants and animals and decompose them, e.g., fungi and bacteria. Decomposers and scavengers help in keeping the environment clean by removing dead plants and animals.

What are decomposers give 2 examples of decomposers?

The two common examples of decomposers are bacteria and fungi. They play an important role in clearing the debris of dead remains of plants and animals and convert them into humus which enriches the nutrients of the soil.

What are decomposers in a food web?

The group of organisms called decomposers forms the final link in the food chain. They break down dead animals and plants and return vital nutrients to the soil. Some decomposers, like fungi, can be seen without a microscope, but much of the decomposition process is carried out by microscopic bacteria.

What are decomposers write the role of decomposers in the environment?

Decomposers include saprophytes such as fungi and bacteria. They directly thrive on the dead and decaying organic matter. Decomposers are essential for the ecosystem as they help in recycling nutrients to be reused by plants.

What are drifting animals in the ocean called?

Plankton are marine drifters — organisms carried along by tides and currents. The word “plankton” comes from the Greek for “drifter” or “wanderer.” An organism is considered plankton if it is carried by tides and currents, and cannot swim well enough to move against these forces.

What are environmental decomposers?

Decomposer: An organism, often a bacterium, fungus, or invertebrate that feeds on and breaks down dead plant or animal matter, making organic nutrients available to the ecosystem. Or: ‘FBI’ (fungi, bacteria, invertebrates)

What are producers in the ocean ecosystem?

The primary producers of the ocean are microscopic phytoplankton, including protists like algae and diatoms. The majority of marine consumers are planktonic, including protists and small animals. Most decomposition is carried out by species of bacteria, enabling nutrients to cycle back to producers.

What are some decomposers in the coral reef?

Decomposers: Fan worms, sea cucumbers, snails, crabs, bristle worms and bacteria are decomposers in the Great Barrier Reef.

What are some decomposers that live in the ocean?

Other sea creatures classified as decomposers include crustaceans and mollusks, bacteria, fungi, sea cucumbers, starfish, sea urchins, and other kinds of marine worms.

What are the 3 ecosystems in the ocean?

These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which have different physical and biological characteristics.

What are the 3 ocean ecosystems?

These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which have different physical and biological characteristics.

What are the 7 aquatic ecosystems?

Aquatic ecosystems include oceans, lakes, rivers, streams, estuaries, and wetlands. Within these aquatic ecosystems are living things that depend on the water for survival, such as fish, plants, and microorganisms. These ecosystems are very fragile and can be easily disturbed by pollution.

What are the biotic factors in the ocean?

Biotic factors include plants, animals, fungi, algae, and bacteria.

What are the decomposers state the role of decomposers in the environment?

Decomposers: Decomposers are organisms that depends on dead or decaying organisms and they carry out the lead or decaying organisms from ecosystem. Role of Decmposers: They breakdown the organic waste and complex organic substances into simple inorganic substances that replenish the fertility of the soil.

What are the main ocean ecosystems?

The major ocean ecosystems span polar, temperate and tropical waters, and include coastal waters, bays and estuaries, the deep sea water column, shallow and deep sea bottom (benthic) environments, sea mounts, island arcs, coral reefs, mangrove systems, salt marshes, frontal zones, and the centers of gyres.

What do decomposers do in the forest class 7?

Answer: Decomposers are micro-organisms that convert the dead plants and animals to humus. Bacteria and fungi are the two types of decomposers. They help in the process of recycling of nutrients by decomposing various dead organisms such as plants and animals to form humus.

What do decomposers do in the nitrogen cycle?

Nitrogen is returned to the atmosphere by the activity of organisms known as decomposers. Some bacteria are decomposers and break down the complex nitrogen compounds in dead organisms and animal wastes. This returns simple nitrogen compounds to the soil where they can be used by plants to produce more nitrates.

What do decomposers do?

Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

What is a decomposer example?

Examples of decomposers are fungi and bacteria that obtain their nutrients from a dead plant or animal material. They break down the cells of dead organisms into simpler substances, which become organic nutrients available to the ecosystem.

What is a carnivore in the ocean?

Seals and sea lions are carnivores that consume fish, squid, and octopuses. Some carnivores, called obligate carnivores, depend only on meat for survival. Their bodies cannot digest plants properly. Plants do not provide enough nutrients for obligate carnivores.
