Marine Microbes Part 1

Front

What is the role of microbes in ecosystems?

Back

They provide food and nutrients, defend against disease, and clean the ocean of waste.

Front

What are some examples of interactions between marine microbes and other organisms?

Back

Symbiosis, predation, competition.

Front

How do marine microbes contribute to the ecosystem?

Back

Marine microbes produce oxygen, recycle nutrients, and form the base of the food chain.

Front

What are Archaea known for?

Back

They are known as 'extremophiles' because they can live in extreme conditions such as very hot, very salty, or very deep water.

Front

What is the composition of the cell wall (frustule) of diatoms?

Back

The frustule is made of silica.

Front

Define marine microbes.

Back

Marine microbes are microscopic organisms that live in ocean environments, including bacteria, archaea, viruses, and protists.

Front

What is the significance of photosynthesis in marine ecosystems?

Back

Photosynthesis by marine microbes produces oxygen and organic matter, supporting marine food webs.

Front

Explain the concept of symbiosis in marine ecosystems.

Back

Symbiosis is a close interaction between two different species, where at least one benefits, such as corals and zooxanthellae.

Front

What is the role of marine microbes in nutrient cycling?

Back

Marine microbes decompose organic matter, recycling nutrients back into the ecosystem.

Front

What are the three main types of symbiotic relationships?

Back

Mutualism, commensalism, and parasitism.
