OBJECTIVE FORESTRY

Detailed explanation-1: -In a balanced ecosystem, they provide food for a wide range of sea creatures. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow.

Detailed explanation-2: -Algae are simple nonflowering plantlike organisms ranging in size from single-celled diatoms (microalgae) to giant multicellular forms such as kelp or seaweed (macroalgae).

Detailed explanation-3: -Planktonic algae, otherwise known as phytoplankton, are microscopic, single celled, free floating algae that can exist wherever the sun penetrates. Planktonic algae thrive under sunny conditions at water temperatures greater than 60°F, and contributes to water’s greenish tint.

Detailed explanation-4: -While the majority of plankton are unicellular and therefore considered to be simple eukaryotic organisms, at the cellular level they are extremely complex. Plankton should be considered an organism in itself and not be compared to a single cell from a multicellular organism.
