What is the role of zooplankton in relation to other wetland wildlife?

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 is zooplankton and why is zooplankton important for life in the ocean?

These microscopic organisms also cycle most of the Earth’s carbon dioxide between the ocean and atmosphere. Zooplankton are the animal-like primary consumers of plankton communities. In turn, zooplankton then become food for larger, secondary consumers such as fish.

Which organisms have the role of the zooplankton in a terrestrial ecosystem?

Other phytoplankton is eaten by zooplankton. The primary consumers of zooplankton are small fish and whales. Secondary consumers are larger fish who eat the smaller fish, which can then also be eaten by larger fish or tertiary consumers.

What would happen if there were no zooplankton?

Nearly all small marine predators eat plankton as their primary food source, so if the plankton were to disappear, then the small predators wouldn’t be far behind. … Not only would those populations be without a significant food source, but local trade would suffer, and their economies would start to collapse.

How do zooplankton affect water quality?

The rise and fall of zooplankton populations leads to decomposition of their dead bodies which is manifested in unpleasant odours and accumulation of organic debris lowering water quality, increasing turbidity and colour, depleting dissolved oxygen and raising organic carbon levels.

What is the role of zooplankton?

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 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 purpose of phytoplankton?

Phytoplankton is the base of several aquatic food webs. 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.

What is the role of phytoplankton in 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 is phytoplankton so important?

Phytoplankton are microscopic marine organisms that sit at the bottom of the food chain. … Phytoplankton get their energy from carbon dioxide through photosynthesis (like plants) and so are very important in carbon cycling. Each year, they transfer around 10 billion tonnes of carbon from the atmosphere to the ocean.

What is meant by zooplankton?

Zooplankton (pictured below) are a type of heterotrophic plankton that range from microscopic organisms to large species, such as jellyfish. Zooplankton are found within large bodies of water, including oceans and freshwater systems.

What can happen because of the change in phytoplankton numbers?

When they die, a percentage sink to the ocean floor, sequestering as much carbon as all terrestrial plants. “If phytoplankton populations were to suffer significant decline, there would be serious consequences for marine food webs, including fisheries, and changes to the balance of nutrient cycling,” says Dr.

What happens if phytoplankton disappeared?

If the phytoplankton are disappearing, Richardson says, “the ocean as a carbon sink is declining, and what that means is ultimately more CO2 will stay in the atmosphere instead of being dissolved in the ocean.” That will translate into a warmer world, which will wipe out even more phytoplankton.

Why should we study about zooplankton?

Why are zooplankton important? As a result of their central position in lake food webs, zooplankton can strongly affect water quality, algal densities, fish production, and nutrient and contaminant cycling.

What affects zooplankton abundance?

Overall, zooplankton species distribution and abundance in the study sites are influenced by various environmental factors such as water transparency and chlorophyll-a content.

What animals eat zooplankton?

Small Predators

Mollusks, small crustaceans (such as shrimp and krill) and small fish like sardines and herring eat large amounts of the zooplankton.
