Select all the correct answers.In which three ways can we use biomass as a source of energy?

by extracting hydrogen from it
by converting it into liquid fuels
by making suitable bacteria act on it
by burning it directly
by mixing it with petroleum-based fuels

Answers

Answer:

The correct ways to use biomass as a source of energy are:

By converting it into liquid fuels: Biomass can be processed into liquid biofuels like biodiesel and bioethanol, which can be used as alternatives to fossil fuels.

By burning it directly: Biomass can be burned directly as a source of heat and energy. This is often done in the form of wood, agricultural residues, or dedicated energy crops.

By making suitable bacteria act on it: Biomass can be used to produce biogas through a process called anaerobic digestion, where bacteria break down organic materials to generate methane, a valuable energy source.
