Verified step by step guidance1
Understand the definition of plankton: Plankton are small organisms that drift in water bodies. They can be found in both marine and freshwater environments.
Identify the types of organisms that make up plankton: Plankton includes both phytoplankton (such as algae and cyanobacteria) and zooplankton (small animals).
Consider the habitats where plankton are typically found: Plankton are usually found near the surface of water bodies where sunlight can penetrate, allowing photosynthesis to occur for phytoplankton.
Differentiate between the various options given: The correct option should include both algae, cyanobacteria, and animals, and specify that they drift near the surfaces of various aquatic environments.
Select the option that accurately describes plankton: The correct answer is 'algae, cyanobacteria, and animals that drift near the surfaces of oceans, lakes, ponds, rivers, and streams', as it encompasses the diverse environments where plankton are found.
