Which organism has the highest biomass?
Organisms at the bottom of the food web have the highest biomass.
Thus, primary producers will greatly outweigh anything else.
From there, primary consumers have the most of the animals.
In an ocean, it will be Phytoplankton (which are photosynthentic plankton).
What is the most abundant animal on the planet by weight?
How do you identify animal biomass?
One way to measure biomass is to obtain the dry weight of an organism (since it is a rough approximation to the amount of biomass) and multiply it by the number of those organisms in a given area. The units are grams per meter squared (or cubed if it is an aquatic ecosystem).
What is the largest species of animal?
What is the most abundant species on Earth?
You may also think humans own the planet. You’d be wrong. Worms like the one in this video are Earth’s animal overlords; nematodes are the most numerically abundant animals on Earth.
What is Pyramid of biomass?
A pyramid of biomass is a graphical representation of biomass present in a unit area of various trophic levels. It shows the relationship between biomass and trophic level quantifying the biomass available in each trophic level of an energy community at a given time.
Why does biomass decrease at each level of the pyramid?
Energy is transferred throughout the food chain as animals at lower trophic levels are consumed by those at higher trophic levels. Therefore, at each stage of the food chain, less energy and biomass is transferred between organisms than at the previous trophic level.
Why are phytoplankton critical to life on Earth?
Phytoplankton are some of Earth’s most critical organisms and so it is vital study and understand them. They generate about half the atmosphere’s oxygen, as much per year as all land plants. Phytoplankton also form the base of virtually every ocean food web. In short, they make most other ocean life possible.
Why do producers have the most biomass?
Answer and Explanation: The first trophic level has the most biomass because it has the most energy according to the 10% rule. The first trophic level is composed of organisms that make their own food, usually green plants. Since these organisms make their own energy, they get 100% of the energy available.
What percentage of biomass is humans?
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.
|individual count||7.0 billion|
|mean living mass of individual||50 kg (incl children)|
|percent biomass (dried)||30%|

Which species has the largest population?
And while they’re both tiny and lacking a backbone, krill are the champs among animals worldwide, in terms of numbers, with a population estimated at 500 trillion.
|Species||Population||Biomass (million tons)|
|Bacteria total||4 quadrillion quadrillion||1,000,000|
|Ants (many species)||10 billion billion||3,000|

What does a biomass pyramid represent?
An ecological pyramid (also trophic pyramid, eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem.
Is the Megalodon bigger than a blue whale?
Monster-size sharks in The Meg reach lengths of 20 to 25 meters (66 to 82 feet). That’s massive, although a tad smaller than the longest known blue whales. Scientists have made estimates of how big C. megalodon got, based on the size of their fossil teeth. Even the largest reached only 18 meters (about 60 feet).
Was there anything bigger than a blue whale?
As the biggest animal ever to have lived, the blue whale (Balaenoptera musculus) seemingly obliterates any other animal’s chances at the length title. Even a new-born blue whale is longer than a giant reticulated python. The largest blue whales are found in the southern hemisphere.
Is a blue whale bigger than dinosaurs?
Now paleontologists have announced a species proposed to be most massive dinosaur ever discovered: an enormous herbivore estimated at over 120 feet long and weighing over 70 tons—or longer than a blue whale and heavier than a dozen African elephants.
What’s the most popular animal in the world?
Top ten most popular animals still endangered, study finds
- the tiger (Panthera tigris),
- the lion (P. leo),
- the elephant (Loxodonta africana, L. cyclotis, and Elephas maximus),
- the giraffe (Giraffa camelopardalis),
- the leopard (P. pardus),
- the panda (Ailuropoda melanoleuca),
- the cheetah (Acinonyx jubatus),
- the polar bear (Ursus maritimus),
Which group has the most species?
Earth > Ask a Scientist About Our Environment > Which animal group has the most organisms?
- Entomologist Toby Schuh answers this question:
- Dear Shelly,
- In terms of numbers of species, insects certainly represent the largest percentage of the world’s organisms.
How many ants are there per human?
There are 7.2 billion humans on the planet today – if we take everyone over the age of 15, they weigh a combined total of about 332bn kg. If we imagine there are 10,000 trillion ants in the world, weighing an average of 4mg, their total weight comes to just 40bn kg.
What is Pyramid of biomass and numbers?
A pyramid of numbers shows the total number of individual organisms at each level in the food chain of an ecosystem. A pyramid of numbers does not always have a regular pyramid shape because it does not take into account the biomass of the organisms.
Why are pyramids of biomass more useful?
Pyramid of biomass. The biomass (amount of living material) of organisms in each trophic level is measured and presented in a pyramid of biomass. It is more accurate as the organism’s size is taken into account. For example, a bar representing 1 tree will be largest as it has more mass than primary consumers.
What is the biomass?
Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. Biomass contains stored energy from the sun. Plants absorb the sun’s energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat.
How do phytoplankton die?
Kevin Drum brings the gloom: So, anyway, as temperatures rise the plankton die. As plankton die, they suck up less carbon dioxide, thus warming the earth further. Which causes more plankton to die.
Is too much phytoplankton bad?
When too many nutrients are available, phytoplankton may grow out of control and form harmful algal blooms (HABs). These blooms can produce extremely toxic compounds that have harmful effects on fish, shellfish, mammals, birds, and even people.
What does plankton do for the ocean?
Most of the plankton in the ocean are plants. Phytoplankton produce their own food by lassoing the energy of the sun in a process called photosynthesis. So for sunlight to reach them, they need to be near the top layer of the ocean. So must zooplankton, which feed on the phytoplankton.
What is wet biomass?
Wet Biomass. This biomass includes organic waste from the farming and food industries, urban waste, microalgae, and other high-moisture-content material that is not frequently recycled.
What is biomass a level biology?
Most of the sugars synthesised by plants are used by the plant as respiratory substrates. The rest are used to make other groups of biological molecules. These biological molecules form the biomass of the plants. Biomass can be measured in terms of mass of carbon or dry mass of tissue per given area.
What trophic level has the most organisms?
Further trophic levels are numbered subsequently according to how far the organism is along the food chain.
- 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.
