What ecosystem has the most producers?
In terrestrial ecosystems most primary producers are plants, and in marine ecosystems, most primary producers are phytoplankton. Both produce most the nutrients and energy needed to support the rest of the food chain in their respective ecosystems.
Which ecosystem has the maximum?
Forest ecosystem have the maximum biomass, because it includes organisms of all tropic levels as compared to pond, lake or grassland ecosystem.
Which of the following is present in maximum number in an ecosystem?
Explanation: Producers or Autotrophs or green Plants are the ones which are found in maximum numbers in the ecosystem.
Which of the following produces maximum biomass in terrestrial ecosystem?
Hint: The water forms the major part of our Earth but the most ecosystem biomass resides on the lands. The animals and plants are usually found to be grown on the land rather than in water.
Is zooplankton a producer?
Phytoplankton are the tiny, plant-like producers of the plankton community. … Zooplankton are the animal-like primary consumers of plankton communities. In turn, zooplankton then become food for larger, secondary consumers such as fish.
Which ecosystem has maximum biodiversity?
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest.
Which ecosystem has maximum organic matter?
Biomass refers to the amount of living organic matter, Forest ecosystem have the maximum biomass, because it includes organisms of all trophic levels as compared to pond, Iake or grassland ecosystem, In forest ecosystems productivity is also high that contributes to maximum biomass.
What is the maximum number of trophic levels found in most ecosystems?
All food chains and webs have at least two or three trophic levels. Generally, there are a maximum of four trophic levels.
What is the maximum number of organisms in a food chain?
Generally in a terrestrial food chain three to four levels can be present. But in an aquatic ecosystem due to great variety in fauna and presence of successive level of carnivory, many more trophic levels can be added there, in an aquatic food chain.
Why is there a maximum number of trophic levels?
The decrease in biomass from lower to higher levels is also represented by Figure 1.1. The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels.
