Plankton consists of __________.

• A. algae, cyanobacteria, and animals that drift near the surfaces of oceans only
• B. photosynthetic organisms that drift near the surfaces of aquatic biomes
• C. algae, cyanobacteria, and animals that belong to the benthic communities of oceans, lakes, ponds, rivers, and streams
• D. algae, cyanobacteria, and animals that occupy the aphotic zones of oceans, lakes, and ponds
• E. algae, cyanobacteria, and animals that drift near the surfaces of oceans, lakes, ponds, rivers, and streams

Answer: (E)

Verified step by step guidance

1. Understand the definition of plankton: Plankton are small organisms that drift in water bodies. They can be found in both marine and freshwater environments.
2. Identify the types of organisms that make up plankton: Plankton includes both phytoplankton (such as algae and cyanobacteria) and zooplankton (small animals).
3. 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.
4. 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.
5. 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.
