used to show energy and energy transformation visually and quantitatively

. This may include primary energy used as raw fuels to feed into a system, energy supply, conversion or transformation, losses and energy being used.

What is the flow of energy in cells?

Energy in living organisms flows

through chemical reactions

. Each step in chemical reaction involves conversion of a set of substances, known as the reactants, into specific products. During chemical reactions, energy stored in chemical bonds is transferred to other, newly created chemical bonds.

How does energy flow through all levels of biological organization and cycles?

Energy flow is

unidirectional

, but matter is cycled in an ecosystem. … Just like energy can't be created or destroyed, matter can't be created or destroyed. Plants use nutrients (molecules made of atoms) in the soil for photosynthesis. Animals eat plants.

Does chloroplast convert light energy into chemical energy?

In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in

glucose

.

What is the energy conversion in a solar cell?

First, a solar cell must absorb solar radiation, converting

the Sun's heat energy into chemical energy

in the device. When light is absorbed, electrons are excited into higher energy levels, temporarily storing chemical energy. Excited electrons behave as charge carriers (current) in an electrical potential.

Which energy is converted into electrical energy by a solar cell?

Photovoltaic energy

is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a nonmechanical device usually made from silicon alloys.

What energy is needed by photosynthetic organism during the process of photosynthesis?

During the process of photosynthesis, cells use

carbon dioxide and energy from the Sun

to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

What happens to solar energy absorbed by plants during photosynthesis?

What happens to the solar energy absorbed by plants during photosynthesis?
