The status of algae in the aquatic food chain is

  • A.consumers
  • B.producers
  • C.host
  • D.small in size

Answer: B

Correct answer: producers

Algae photosynthesise, so they make their own food from CO2 and sunlight and stand at the base of the aquatic food chain as producers. Everything else in the water ultimately depends on them - and on the oxygen they release, which is a large share of the world’s supply.
