Which organisms does not require sunlight to live?

Which organisms does not require sunlight to live?

Most organisms, including fungi, animals and many microorganisms, do not require sunlight to live, except indirectly. Organisms that require organic material (food) to survive, like we do, are collectively called heterotrophs.

Which kind of organism does not generally require oxygen or sunlight to live?


In what way are plants in a sunny meadow and sulfur bacteria in a deep sea vent alike quizlet?

In which way are plants in a sunny mountain meadow and sulfur bacteria in a deep-sea volcanic vent alike? They both produce carbohydrates and oxygen. more productive because bacteria living on the roots of legumes fix nitrogen in the soil.

What goes in Box 5 of the food web in Figure 3 2?

Decomposer goes in the box five of the food web. Further Explanation: The first step of the food chain starts with energy which is absorbed by the plants during the process called photosynthesis. Photosynthesis is the process by which plants make their own food by using sunlight, carbon dioxide and other nutrients.

What animals eat both producers and consumers?

Animals that eat both producers and consumers are called omnivores. When animals die, decomposers can break them down so that plants can use the nutrients again and the cycle can start over.

What is the difference between a primary consumer and a secondary consumer?

The organisms that eat the producers are the primary consumers. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number.

What type of consumer is a bacteria?

This level is made up of herbivores: bacteria, fungi, actinomycetes, nematodes, mites, snails, slugs, earthworms, millipedes, sowbugs and worms. Note that some types of mites are carnivores. The most productive members of your compost pile’s food web are the bacteria, which are chemical decomposers

Is bacteria that perform chemosynthesis a consumer?

Phytoplankton, tiny organisms that live in the ocean, are autotrophs. Some types of bacteria are autotrophs. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.

Which bacteria is associated with chemosynthesis?

Examples of chemosynthetic bacteria include:

  • Venenivibrio stagnispumantis.
  • Beggiatoa.
  • T. neapolitanus.
  • T. novellus.
  • ferrooxidans.

What is chemosynthesis example?

The energy source for chemosynthesis may be elemental sulfur, hydrogen sulfide, molecular hydrogen, ammonia, manganese, or iron. Examples of chemoautotrophs include bacteria and methanogenic archaea living in deep sea vents

Where do chemosynthetic bacteria live?

hot springs

What Animals use chemosynthesis?

Chemosynthetic microbes live on or below the seafloor, and even within the bodies of other vent animals as symbionts. Where microbial mat covers the seafloor around vents, grazers such as snails, limpets, and scaleworms eat the mat, and predators come to eat the grazers.

How old are hydrothermal vents?

Some of the earliest evidence for microbial life on Earth comes from rocks located in Canada that formed within hydrothermal vent environments around 4 billion years ago.

Do photosynthetic bacteria need sunlight live?

Scientists have found a photosynthetic bacterium that doesn’t live off the light of the sun. Instead, it uses the dim light given off by hydrothermal vents some 2,400 meters below the ocean’s surface. This light energy is then transferred to the organism’s reaction center, where photosynthesis takes place

Can bacteria grow without sunlight?

Answer 2: Surprisingly, no. There are bacteria that live in hot springs and other volcanic water that get their energy from chemicals released as a result of volcanic activity. They do not need light, and they do not need oxygen, and the Earth’s interior provides them with heat, so they can live without the sun

Does photosynthetic bacteria evolve oxygen?

The Cyanobacteria are oxygenic – they can oxidize water and evolve oxygen and possess both type I and type II reaction centers.

What type of plants live in the deep ocean?

Deep Ocean Plants

  • Red Algae Seaweeds. More than 2,000 species of red algae seaweeds can be found in the ocean.
  • Phytoplankton. Phytoplankton rely on sunlight to photosynthesize, so they are generally found in shallower ocean waters.
  • Sea Grasses. Sea grasses were once thought to live only in shallow waters of less than 30 feet.
  • Bacteria.

What plants and animals live in the ocean ecosystem?

Ocean Animals The ocean contains a large variety of animal life, including fish, mollusks, dolphins, seals, walruses, whales, crustaceans, bacteria, sea anemones and many others. Most marine animals live in the top two ocean zones, where they have access to plants and other ocean animals to eat
