Photosynthesis & Cell Respiration

Energy from the Sun:Radiant Energy: energy that can travel through the vacuum of space

Photosynthesis & Cell Respiration

Energy from the Sun:Radiant Energy: energy that can travel through the vacuum of space

e.g. -ultra-violet radiation-visible light

Photosynthesis & Cell Respiration

Photosynthesis & Cell Respiration

Light Energy: visible forms of radiant energy(ROYGBIV)

Photosynthesis & Cell Respiration

Light Energy: visible forms of radiant energy(ROYGBIV)-70% is absorbed by the Earth and converted into thermal energy

Photosynthesis & Cell Respiration

Thermal Energy: (infra-red radiation) the form of energy transferred during heating or cooling

Photosynthesis & Cell Respiration

Thermal Energy: (infra-red radiation) the form of energy transferred during heating or cooling

-thermal energy keeps the Earth warm enough for life to exist.

Photosynthesis & Cell Respiration

Photosynthesis: the process in which the Sun's energy is converted into chemical energy

Photosynthesis & Cell Respiration

Photosynthesis word equation:

sunlightcarbon + water sugar + oxygendioxide

Photosynthesis & Cell Respiration

Cell Respiration: the process by which the energy from sugar is converted into useable energy in cells

Photosynthesis & Cell Respiration

Cell Respiration word equation

sugar + oxygen energy + carbon + water

Photosynthesis & Cell Respiration

Producer: an organism that makes its own energy from photosynthesis

e.g. plants

Photosynthesis & Cell Respiration

Producer: an organism that makes its own energy from photosynthesis

e.g. plants

Consumer: an organism that gets its energy by eating other organisms

e.g. animals
