What is microbial ecology concerned with?

The impact of climate change on plant life

The exploration of space habitats

The study of large animals in various ecosystems

The relationship of microorganisms with one another and with their surroundings (correct)

Why is microbial ecology considered important?

Because it studies only Archaea

Because it disregards the role of microorganisms in the ecosystem

Because microorganisms make up most of the biomass on Earth (correct)

Because it focuses on ecological theory only

Why are microorganisms referred to as 'the unseen majority'?

Because they are visible to the naked eye, unlike larger animals

Because their impact on ecosystems is minimal

Because they are always present in plain sight

Because they make up most of the Earth's biomass but are often overlooked (correct)
