The Sun’s energy is needed for plants to make food through a process called photosynthesis. In photosynthesis, green plants capture the Sun’s energy. They use it to make sugars from water and carbon dioxide. Plants are considered a producer in the food chain.

The zebra and lion both obtain the sun’s energy indirectly from the energy that the grass obtained through photosynthesis. organisms. Some heterotrophs, such as fungi, absorb their food from other organisms.

Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. The glucose gives plants energy.

The first link of every food chain begins with the Sun. The Sun has to give energy to the first trophic level or first transfer of energy between…

carbon dioxide: a type of gas found in Earth’s atmosphere • Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis.

PLANTS are ‘PRODUCERS’ of energy. They use SUNLIGHT + water, minerals and carbon dioxide to make energy. They get their energy DIRECTLY from the sun.

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

The 10% rule states that between one trophic level to the next only 10% of the energy is passed on to the next. So if producers have 10,000 J of energy stored through photosynthesis, then only 1000 J is passed on to primary consumers.

The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model.

Ten Percent Rule: What happens to the other 90% of energy not stored in the consumer’s body? Most of the energy that isn’t stored is lost as heat or is used up by the body as it processes the organism that was eaten.

Explanation: When energy moves between trophic levels , 10% of the energy is made available for the next level. Roughly ten percent of the previous trophic level’s energy is available to the level immediately higher up. This is called the 10% Rule.

The 10 percent rule states that when an organism/species is consumed by another organism/species of higher trophic level, the latter (discards, stores, transforms) only 10% of energy. Approximately 10 % of the energy at one trophic level is transferred to the next trophic level.

Plants are also known as autotrophs because they can produce organic compounds from inorganic chemicals. Bacteria, fungi, worms, and snails recycle the garbage of dead matter and give back nutrients into the ecosystem. They are the final link in the energy flow in a food chain or a food web.

trophic level

In environmental science, biomass is the organic matter from living organisms whether wastes or dead animals or plants that can be used as fuel in powering power plants to produce electricity (mainly). Therefore from that definition, the correct answer is: All materials that form from the remains of living organisms.

No energy source is perfect, biomass included. Though it is renewable, there are both benefits and downsides to generating electricity using biomass energy plants….Pros and cons 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 …

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. These are called biomass feedstocks. Biomass energy can also be a non-renewable energy source.

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.

Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes.

In fact, the big advantage of bioenergy is that its use reduces the use of such non-renewable energy sources. There are three major ways in which the energy in plants is utilized: direct burning, conversion to gas, and conversion to alcohol.

“Biomass is far from “clean” – burning biomass creates air pollution that causes a sweeping array of health harms, from asthma attacks to cancer to heart attacks, resulting in emergency room visits, hospitalizations, and premature deaths.”

Biomass is considered a renewable energy source because supply does not run out. As opposed to fossil fuels that take millions of years to form, biomass grows and re-grows relatively quickly through the photosynthetic process.

Cons

• Biomass from wood can lead to deforestation and/or it may compete directly with food production (e.g. corn, soy)
• Requires (little) water to grow.
• Some methane and CO2 are emitted during production, not totally clean when burned (NOx, soot, ash, CO, CO2)
• Algae require phosphorus as a fertilizer.

Regardless of the source of the fuel – low carbon or high carbon – burning stuff is just inherently a dirty process. The combustion of biomass in power plants releases harmful air pollutants such as particulates, NOx, and SOx.

The International Renewable Energy Agency has released a new report that determined many sources of renewable energy are now cheaper than fossil fuels. Within the report, IRENA indicates biomass can provide dispatchable baseload electricity at very competitive costs.

The IRENA report found that solar and onshore wind are the cheapest energy sources. It states that in 2017 wind turbine prices had an average cost of $0.06 per kWh, and at times dropped to $0.04 per kWh.
