Q. Consider the following statements about Plankton:
1.Plankton includes both microscopic plants (phytoplankton) and microscopic animals (zooplankton).
2.The distribution of plankton in aquatic ecosystems is primarily controlled by water currents rather than their own locomotion.
Which of the statements given above is/are correct?
Answer: C
Notes:
Explanation:
- Plankton is a collective term for organisms floating in surface waters of rivers, lakes, and oceans.
- It includes phytoplankton (algae, microscopic plants) and zooplankton (crustaceans, protozoans).
- Since planktons have very limited locomotory power, their distribution is largely determined by aquatic currents.
