What are the trophic levels in aquatic ecosystem?

1st Trophic Level : Primary producers. Makes its own food (autotrophic) Phytoplankton, seaweed. 2nd Trophic Level : Herbivorous Consumers (primary consumers) Consumes producers Zooplankton, cockles. 3rd Trophic Level : First level carnivorous consumers (secondary consumers) Consumes primary consumers.

What are trophic levels write an aquatic food chain?

Answer: Phytoplanktons are the primary producers forming the first trophic level. Zooplanktons are primary consumer forming the second trophic level. At last large fishes are the tertiary consumers forming fourth trophic level.

What are the 5 trophic levels in order?

There are five key trophic levels in an ecosystem, from simple plants that get energy from sunlight to apex predators at the top of the food chain.

  • Plants and Algae. Plants and algae comprise the lowest level of the trophic system. …
  • Primary Consumers. …
  • Secondary Consumers. …
  • Tertiary Consumers. …
  • Apex Predators.

What are the 4 trophic levels?

Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers.

What trophic levels do plankton occupy in the food web of aquatic water systems?

Producers. Primary producers — including bacteria, phytoplankton, and algae — form the lowest trophic level, the base of the aquatic food web. Primary producers synthesize their own energy without needing to eat. Many photosynthesize, using the sun’s energy to build carbohydrates.

What is aquatic food chain Class 10?

Aquatic food chains:

Phytoplanktons→ Zooplanktons → Small crustacians→ Predator insect → Small fish → Large fish → Crocodile. Phytoplanktons→ Zooplanktons → Small fish → Large fish → Shark. Phytoplanktons→ Zooplanktons → Fish → Crane → Hawk.

What are trophic levels define and draw?

(A) Trophic level is the steps in a food chain where transfer of food in the form of energy takes place between organisms. At each step in a food chain is an organism that forms the trophic level. A food chain consisting of four trophic levels.

What are the 6 trophic levels?

Examples of Trophic Level

  • Primary Producers. Primary producers, or ”autotrophs”, are organisms that produce biomass from inorganic compounds. …
  • Primary Consumers. …
  • Secondary Consumers. …
  • Tertiary Consumers. …
  • Apex Predators.

What are different trophic levels?

There are 4 trophic levels it includes producers, herbivores (primary consumers), carnivores (secondary consumers), predators (tertiary consumers).

What is the 5th trophic level called?

The fifth trophic level contains organisms known as Quaternary consumers or Apex predators. These organisms consume organisms in the consumer levels below them and have no predators. They are at the top of the food chain.. Decomposers are organisms that break down dead or decaying organisms.

What trophic level are decomposers?

They are the “last trophic level” in some hierarchies because they feed on everything (National Geographic). However, according to the strict trophic level definition they would be primary consumers.

What are the levels of consumers?

Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. At the top of the system are the apex predators: animals who have no predators other than humans. Help your class explore food chains and webs with these resources.

What are aquatic decomposers?

Overall, the main decomposer organisms in marine ecosystems are bacteria. Other important decomposers are fungi, marine worms, echinoderms, crustaceans and mollusks. In the colder ocean waters, only bacteria and fungi do the decomposing because the other creatures cannot survive in the extreme conditions.

What type of trophic level is zooplankton?

Zooplankton constitute the second trophic level in the food chain, and include microscopic one-celled organisms called protozoa as well as small crustaceans, such as copepods and krill, and the larva of fish, squid, lobsters and crabs. Organisms at this level can be thought of as primary consumers.

Are zooplankton primary consumers?

The zooplankton community is composed of both primary consumers, which eat free-floating algae, and secondary consumers, which feed on other zooplankton.
