Biomass is the largest store of nutrients due to the vast arrays of plants found in the TRF. Few nutrients are in the litter, due to their rapid decomposition as a result of high temperatures.
Why does the nutrient cycle in a rainforest have a larger biomass store?
The majority of nutrients in the tropical rainforest are stored in the biomass. Nutrients are rapidly recycled in the tropical rainforest biome. … The warm, moist climate provides ideal conditions for decomposers to break down organic material in the litter layer very quickly.
Why is biomass important in an ecosystem?
Biomass can be measured for all types of vegetation and therefore comparisons can be made among different communities or ecosystems. … Biomass is considered a good measure of plant dominance on a site because it reflects the amount of sunlight, water and minerals a plant is able to capture and turn into plant mass.
What are the three stores of the nutrient cycle?
The nutrient cycle describes how nutrients are transferred around an ecosystem. It has 3 stores: li&er, soil and biomass. Nutrients are transferred between these stores. The biggest store is the biomass which is made up of all the biolc components.
What does biomass measure?
Biomass (B) is a measurement of how much living tissue mass for a population is present at one instant in time (or averaged over several periods of time), and its units are mass (or energy) per unit area (e.g., g/m2) (Benke 1993).
Is a valuable wood grown in the rain forest?
Much of it is high-value lumber, such as mahogany (South American and African), ipę (“Brazilian walnut”), jatoba (“Brazilian cherry”), ramin and nyatoh, used for furniture, doors, coffins, boardwalks, decking, plywood, and flooring.
How tall are the trees in the emergent layer?
The top layer of the rainforest is the emergent layer. Here, trees as tall as 60 meters (200 feet) dominate the skyline. Foliage is often sparse on tree trunks, but spreads wide as the trees reach the sunny upper layer, where they photosynthesize the sun’s rays.
What is the largest biomass on Earth?
Copepods may form the largest biomass of any animal species group. Antarctic krill form one of the largest biomasses of any individual animal species.
…

What can be done with biomass?
Direct combustion is the most common method for converting biomass to useful energy. All biomass can be burned directly for heating buildings and water, for industrial process heat, and for generating electricity in steam turbines. Thermochemical conversion of biomass includes pyrolysis and gasification.
What are 3 benefits of biomass?
Some of the advantages of biomass energy are:
- Biomass is always and widely available as a renewable source of energy. …
- It is carbon neutral. …
- It reduces the overreliance of fossil fuels. …
- Is less expensive than fossil fuels. …
- Biomass production adds a revenue source for manufacturers. …
- Less garbage in landfills.

How are nutrients lost from the soil?
Nutrients can be lost in a number of ways. Soluble nutrients like nitrate and potassium can be lost in runoff and drainage water, whereas less soluble nutrients like phosphorus are more likely to be lost with sediments moving in eroding soils and run-off water. Broadcast fertilisers on the soil surface are at risk.
Why is tropical soil red?
The majority of tropical soils have shades of colour varying from yellow and brown to red. The reddish colour reflects the presence of iron oxides that form as a result of chemical weathering.
Why are rainforest soils infertile?
The rainforest nutrient cycling is rapid. … However, as these nutrients are in high demand from the rainforest’s many fast-growing plants, they do not remain in the soil for long and stay close to the surface of the soil. If vegetation is removed, the soils quickly become infertile and vulnerable to erosion.
How do you calculate biomass?
Biomass is really an expression of net change – because there can be significant changes to the biomass within the designated time period. The calculation is defined as: biomass(net) = increase biomass(gross) — decrease biomass(gross).
What percentage of biomass is humans?
Humans account for just 0.01% of biomass
But these metrics can make it difficult to compare between taxa: small organisms may have a large population but still account for a very small percentage of Earth’s organic matter.
What are 5 types of biomass?
Biomass feedstocks include dedicated energy crops, agricultural crop residues, forestry residues, algae, wood processing residues, municipal waste, and wet waste (crop wastes, forest residues, purpose-grown grasses, woody energy crops, algae, industrial wastes, sorted municipal solid waste [MSW], urban wood waste, and …
