The tropic level that contains the greatest biomass in most ecosystems are producers. This occurs because producers get there energy from the sun, the sun is the most available resource and so there are the most at that level.
What trophic level contains the greatest biomass in most ecosystems?
The trophic level that contains the greatest biomass in most ecosystems is the producers.
What trophic level contains the most biomass and why?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers. These include things like grass, trees, and flowers.
Which ecosystem has the greatest biomass?
About 18% of this plant biomass is eaten by the land animals. However, in the ocean, the animal biomass is nearly 30 times larger than the plant biomass. Most ocean plant biomass is eaten by the ocean animals.

Why does the first trophic level has the most biomass?
The first trophic level has the most biomass because it has the most energy according to the 10% rule.
Which trophic level has lowest biomass?
The trophic level that has the least biomass is usually the tertiary consumers.
What is the most important trophic level?
Primary producers are important to the whole food chain because they are the original source of energy that is then passed between other organisms. The next three trophic levels contain organisms known as consumers.
What trophic level are humans?
The World’s Food Chain
Next come the omnivores that eat a mixture of plants and herbivores. That’s where humans rank, with a trophic level of 2.2. Above us are carnivores, such as foxes, that eat just herbivores.
What are the six trophic levels?
What Are the Trophic Levels in Our Ecosystem?
- Plants and Algae. Plants and algae comprise the lowest level of the trophic system. …
- Primary Consumers. Herbivores belong in the second level of the trophic system. …
- Secondary Consumers. A specialized type of carnivore belongs to the third level of the trophic system. …
- Tertiary Consumers. …
- Apex Predators.

What does trophic mean?
(Entry 1 of 2) 1 : of or relating to nutrition : nutritional trophic disorders. 2 : tropic entry 3. 3 : promoting cellular growth, differentiation, and survival.
Which organism is a primary consumer?
The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers.
How do producers increase biomass?
In ecology, productivity is the rate at which energy is added to the bodies of organisms in the form of biomass. … Producers such as plants use some of this energy for metabolism/cellular respiration and some for growth (building tissues).
Which plants on Earth are the most abundant in biomass?
Angiosperms, or flowering plants, make up around 90% of all plant species. They cover a large proportion of the Earth’s land, account for much more biomass than terrestrial animals and provide the structural canvass of the vast majority of land-based eco-systems.
Why is energy transferred 10%?
Energy is transferred along food chains, however, the amount of available energy decreases from one trophic level to the next. The reason for this is that only around 10 per cent of the energy is passed on to the next trophic level. … it is released as heat energy during respiration.
What is trophic efficiency?
Trophic efficiency The ratio of production at one trophic level to production at the next lower trophic level. is calculated by the percentage of energy that consumers in one trophic level gain and convert into biomass from the total stored energy of the previous trophic level.
Which trophic level has the most energy?
Since the source of energy is the sun, the trophic level representing producers (plants) contains the most energy.
