Freshwater aquatic plankton, viewed under microscope
Plankton are microscopic organisms that live suspended in the water environment and form a very important part of the freshwater community. They move via convection or wind-induced currents. In almost every habitat of a freshwater ecosystem, thousands of these organisms can be found, and due to their small size and simplicity, they are capable of occupying large expanses of water and multiplying at an exponential rate.
Plankton can be subdivided into two categories.
They are relatively unspecialized as their environment does not resist the large populations that can exist within their environment. Physiologically, there are many evolutionary adaptations that can be found that assist in the buoyancy of them and prevent their deaths by allowing themselves to be suspended in the water away from harm.
They can be found in large amounts in a small area, and as they are consumed in large numbers by herbivores (phytoplankton) and carnivores (zooplankton), they reproduce asexually to keep population numbers up. This is opposed to sexual reproduction with other organisms, which would take longer although it would increase genetic variation within the species.
Many factors can affect the distribution of plankton in an ecosystem, which has a detrimental effect on the rest of the ecosystem because, as mentioned, they form an essential part of the ecosystem. Phytoplankton harness new energy from sunlight and provide many other organisms as a means of food due to this while zooplankton are also an important source of food for many species. In light of this, a knock-on effect of starvation would occur if there is a lack of plankton in a particular environment.
Phytoplanktons are more abundant in areas with a high intensity of light, as they can convert this light energy into chemical energy while higher temperatures increase growth and multiplication of both phytoplankton and zooplankton. Elementary, the amount of available nutrients in the environment also plays a part in the distribution and density of phytoplankton.
