The level with the least biomass are the highest predators in the food chain, such as foxes and eagles. In a temperate grassland, grasses and other plants are the primary producers at the bottom of the pyramid.
Which ecosystem has the least biomass?
Answer and Explanation:
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 lowest trophic level in an ecosystem?
Plants and algae comprise the lowest level of the trophic system. Called primary producers or autotrophs, plants and other organisms create their own food using photosynthesis. By using energy gleaned from the sun and nutrients gathered from the soil or water, plants and algae can manufacture food.
What trophic level has the least energy?
It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.
Which level has the most 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. These include things like grass, trees, and flowers.
Which is the largest ecosystem on earth?
The World Ocean is the largest existing ecosystem on our planet. Covering over 71% of the Earth’s surface, it’s a source of livelihood for over 3 billion people.
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 the 3rd trophic level called?
Trophic Levels
| Trophic Level | Where It Gets Food |
|---|---|
| 1st Trophic Level: Producer | Makes its own food |
| 2nd Trophic Level: Primary Consumer | Consumes producers |
| 3rd Trophic Level: Secondary Consumer | Consumes primary consumers |
| 4th Trophic Level: Tertiary Consumer | Consumes secondary consumers |
What are the 4 food chains?
What Are the 4 Levels of the Food Chain?
- PRODUCERS: At the bottom of the food chain, plants are natural producers and provide food and nutrients to consumers.
- HERBIVORES: Herbivores nourish on plants and insects.
- PREDATORS: Predators prey on herbivores or other predators.
- DECOMPOSERS: When an animal dies, scavengers and decomposers break them down.

What is the fifth 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 has the most energy?
Trophic level 1 has the greatest amount of energy. Trophic level 4 has the least amount of energy.
What is the first trophic level?
The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
What has the least amount of energy?
This is because red has the longest wavelength of visible light and the longest frequency of any visible light colour. Red light has a wavelength of 610 – 740nm. Meaning that red has the least amount of energy level, whereas violet has the highest amount of visible light.
What has the greatest biomass in an ecosystem?
The trophic level that contains the greatest biomass in most ecosystems is the producers.
How much is biomass worth?
The currency Biomass price on Xbox One is 372 Credits, average 360 Credits in this week, Unchange compared to the prices in the previous 15 days.
How much biomass is in the ocean?
The ocean covers 71% of the Earth’s surface and occupies a much larger volume than the terrestrial environment, yet land biomass, at ≈470 Gt C, is about two orders of magnitude higher than the ≈6 Gt C in marine biomass, as shown in Fig.
