Why are phytoplankton a key part of the marine ecosystem?

Like plants, they produce oxygen through photosynthesis, providing aquatic animals, as well as those found on land, with the oxygen necessary for respiration. Phytoplankton also make up the first step in the marine food chain and thus serve as food sources for smaller sea organisms, which in turn sustain larger ones.

Why are phytoplankton so important to the marine ecosystem?

They provide the base for the entire marine food web. … Zooplankton and other small marine creatures eat phytoplankton and then become food for fish, crustaceans, and other larger species. Phytoplankton make their energy through photosynthesis, the process of using chlorophyll and sunlight to create energy.

Why are phytoplankton a key part of the marine ecosystem quizlet?

The advantage that phytoplankton have because they have a greater surface area to body mass is that they have greater resistance to sinking, as the surface is in frictional contact with the surrounding water.

What is the role of zooplankton in an aquatic ecosystem?

The zooplankton community is an important element of the aquatic food chain. These organisms serve as an intermediary species in the food chain, transferring energy from planktonic algae (primary producers) to the larger invertebrate predators and fish who in turn feed on them.

What are the benefits of phytoplankton?

Phytoplankton offers a broad spectrum of minerals that come from the sea – magnesium, phosphorus, potassium, calcium, iron and zinc. These minerals promote good health and wellness; they are also responsible for maintaining, or assisting with, body functions that are required to sustain life.

What is the difference between phytoplankton and zooplankton quizlet?

What is the main difference between phytoplankton and zooplankton? Phytoplankton produces food via photosynthesis whereas zooplankton must eat food.

What is the difference between phytoplankton and zooplankton?

Phytoplankton is a group of free-floating microalgae that drifts with the water current and forms an important part of the ocean, sea, and freshwater ecosystems. Zooplankton is a group of small and floating organisms that form most of the heterotrophic animals in oceanic environments.

What is phytoplankton?

Phytoplankton are microscopic marine algae.

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.

Why are zooplankton important in lakes?

Zooplankton are a vital component of the Great Lakes food web and the Great Lakes fishery. … Decreasing zooplankton populations means less food for fish, which results in fewer, smaller fish. Also, changes in zooplankton populations and diversity can indicate water quality changes in the lakes.

What role do zooplankton play in carbon cycle?

Within this food web, zooplankton serve both as trophic links between primary producers and higher trophic levels (such as fish) and as recyclers that transform particulate carbon and nutrients into dissolved pools.

What is the significant role of zooplankton in the trophic dynamics of the pelagic environment?

Zooplankton play a key role in the pelagic realm as a major link between primary producers and higher trophic levels, either directly or indirectly via protozooplankton, so are subject to either bottom–up or top–down control.

Is marine phytoplankton good for plants?

Marine Phytoplankton are Micro Algae full of nutrients, vitamins and minerals. It gives the growth and health your plants deserve.

What does phytoplankton do in reef tank?

Phytoplankton are incredibly important to the aquatic food chain. They utilize nutrients in the water along with carbon dioxide to reproduce, and in the process, create essential fatty acids (EFAs) critical to the health and development of most marine organisms and people too (Omega 3 fatty acids-fish oils).
