    The correct answer is Lichen.

    Key Points

    Due to the sensitivity of Lichens to sulphur dioxide, it is very useful as a biological indicator of Sulphur-dioxide pollution.

    The efficient absorption systems of Lichens result in rapid accumulation of sulphur during high levels of sulphur dioxide pollution.

    Important PointsBryophytes are called the “amphibians” of the plant kingdom.

    They can live on land but for reproduction and fertilization, need water essentially.

    Algal blooms are the result of a nutrient, like nitrogen or phosphorus from fertilizer runoff, entering the aquatic system and causing excessive growth of algae.

    An algal bloom affects the whole ecosystem.

    Pseudomonas is a common genus of bacteria, which can create infections in the body under certain circumstances.
