What is biomass energy GCSE?
Biomass energy is generated from decaying plant or animal waste. It can also be an organic material which is burned to provide energy, eg heat, or electricity. An example of biomass energy is rapeseed (yellow flowers you see in the UK in summer), which produces oil.
What is biomass GCSE geography?
Biomass is the mass of material in the bodies of animals and plants (total mass of living matter) Abiotic. Abiotic means the non-living, chemical and physical components of the ecosystem and includes: Climate- in particular the seasonal pattern of temperature and precipitation.
What is the main disadvantage of biomass?
One of the disadvantages of biomass energy is the amount of space that it requires. A great deal of land and water are needed for some biomass crops to be produced and, when they have grown, the product requires a large amount of storage room before being converted into energy.
What is biomass BBC Bitesize ks3?
Biomass, which is made from waste plant or animal material, can be burned to produce heat and electricity. The heat produces steam to power electricity generators. Biomass is a clean fuel and uses waste products; however, it costs money to transport and is as expensive as coal.
What are the advantages of nonrenewable resources?
Advantages of Non-Renewable Energy
- The main advantages of non-renewable energies is that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles.
- Non-renewable energy is cost effective and easier to product and use.
What is biomass geography?
Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals. The most common biomass materials used for energy are plants, wood, and waste.
What are the advantages and disadvantages of renewable energy sources?
Renewable energy sources are clean to use as there are fewer greenhouse gas emissions. The technology required is often expensive to purchase. Usually, the energy is produced at a slower rate than when using fossil fuels. Due to use of a stable source of energy, the cost of renewable fuels does not change much.
Why is biomass bad for the environment?
When we burn biomass for heat or electricity, it releases carbon dioxide into the atmosphere. For example, consider electricity from woody biomass: burning wood to produce electricity emits carbon dioxide into the atmosphere, but trees will re-grow and capture the emitted carbon dioxide.
Why is wood not considered to be biomass?
Wood is considered biomass because it was recently a plant. Fossil fuels are not considered biomass because they are the remains of organisms that died millions of years ago and have been chemically changed from the original living tissue.
How is biomass related to the food chain?
The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. Biomass is living or recently dead tissues. The mass of your body is biomass because you are alive.
Why is the mass of your body considered biomass?
The mass of your body is biomass because you are alive. Wood is considered biomass because it was recently a plant. Fossil fuels are not considered biomass because they are the remains of organisms that died millions of years ago and have been chemically changed from the original living tissue.
Why are fossil fuels are not considered biomass?
Fossil fuels are not considered biomass because they are the remains of organisms that died millions of years ago and have been chemically changed from the original living tissue. The amount of biomass can be measured at different trophic levels in a food chain.
