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.
Why do producers have the greatest biomass?
Autotrophs, the producers in a food web, convert the sun's energy into biomass. Biomass decreases with each trophic level. There is always more biomass in lower trophic levels than in higher ones. Because biomass
decreases with each trophic level
, there are always more autotrophs than herbivores in a healthy food web.
What has the greatest biomass in an ecosystem?
The trophic level that contains the greatest biomass in most ecosystems is
the producers
.
Where is most biomass found?
For animals, most biomass is concentrated in
the marine environment
, and for bacteria and archaea, most biomass is concentrated in deep subsurface environments.
Which level of consumers contains the largest biomass?
In this case, the trophic level which contains the greatest biomass is
the producers
, which is the lowest trophic level. This means that there are more producers than the first level consumers. Examples of producers include plants, algae, grasses, trees, and flowers.
What kingdom has the least biomass?
The trophic level that has the least biomass is usually the
tertiary consumers
. Tertiary consumers are at the top of the food web and subsequently…
What is the 10 rule?
Lesson Summary. The 10% Rule means that
when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on
. An energy pyramid shows the feeding levels of organisms in an ecosystem and gives a visual representation of energy loss at each level.
Which pyramid is always upright?
Complete answer:
Pyramid of energy
is the only pyramid that can never be inverted and is always upright. This is because some amount of energy in the form of heat is always lost to the environment at every trophic level of the food chain.
Why is energy transferred 10%?
The amount of energy at each trophic level decreases as it moves through an ecosystem
. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Why do producers have the most energy?
Explanation: Producers (plants) have the most energy in a food chain or web (besides the sun) and they
give an organism more energy than a primary consumer or secondary consumer would
. Plants absorb about 1% of the sunlight that strikes them. The rest is reflected back into space or transmitted through objects.
How is biomass made?
Biomass is renewable organic material that comes from plants and animals. … Plants produce biomass
through photosynthesis
. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes.
Is fuel a biomass?
Biomass is
fuel
that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power.
Which plants have the most 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.
Which level of the food pyramid has the largest biomass?
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.
Are jellyfish secondary consumers?
Fish, jellyfish and crustaceans are
common secondary consumers
, although basking sharks and some whales also feed on the zooplankton.
Which organism is a primary consumer?
Primary consumers make up the second trophic level. They are also called
herbivores
. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.
