b) Are single celled organisms
c) Are photosynthetic protists
d) Are good indicators of water pollution​

Answer 1

Answer:

b) are good indicators of water pollution

Answer 2

They differ as they have cell walls impregnated with silica

• These creatures are minuscule and float on water currents in a passive manner.
• These are the primary producers in the water since they are abundant and photosynthetic in nature.
• They are indestructible because their cell wall system is composed of silica. Their cell walls persist in their surroundings after they die.
• It has accumulated over billions of years and is known as 'Diatomaceous Earth,' which is utilised in oil cleaning and filtration.
