energy flows within systems
Energy is the capacity to do work, cellular work includes building complex molecules and moving substances in and out of the cell.
Chemical Energy: potential energy stored in the bonds of biological molecules (Food)
Potential Energy: stored energy (Food)
Kinetic Energy: the energy of motion or movement, (muscle movement, digestion breaks down food and releases energy)
Heat: the kinetic energy generated by random movements of molecules or atoms (transfer of energy from food to muscle to environment
energy Systems in plants
Autotroph: plants are autotrophs, they capture energy from the sunlight through photosynthesis
Photosynthesis: the process by which plants and other autotrophs use the energy of sunlight to make energy rich molecules using carbon dioxide and water
Plants take sunlight and make sugars, glucose sugar, chemical energy.
The glucose sugar goes to:
Chloroplast: the organelle in the plant cell where photosynthesis occurs
Sunlight has Photons: packets of light energy, each with a specific wavelength and quantity of energy
A photon is both a wave and a particle
Light Energy: the energy of the electromagnetic spectrum of radiation
Chlorophyll: The pigment present in the green parts of plants that absorbs photos of light energy during photosynthesis
ATP, Adenosinetriphosphate: The molecules that cells use to power energy-requiring functions
Carbon Fixation: the conversion of inorganic carbon CO2 into organic forms, sugars
An enzyme present in plant chloroplasts, involved in fixing atmospheric carbon dioxide during photosynthesis and in oxygenation of the resulting compound during photorespiration

Trophic Cycle: A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Trophic Cascade: When something that a large predator does affects the rest of the food chain. An ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain, which often results in dramatic changes in ecosystem structure and nutrient cycling.
