What is energy
Energy is the ability to do work or cause change.
Kinetic Energy
Energy of motion
Potential Energy
Stored energy
Chemical Energy
Energy stored in chemical bonds (e.g., in food and fuel)
Light Energy
Energy from the sun, important for photosynthesis
Energy supplies the powers for life processes like growth, reproduction, movement, and
repair. Ex:
Muscle contraction, nerve impulses, cell division
Ultimate source of energy for most life on Earth. Plants capture sunlight during
photosynthesis
The Sun
Animals and humans get energy by eating plants or other organisms
Food
Photosynthesis occurs in
plants, algae, and some bacteria
Photosynthesis converts _______ to _______
light energy, chemical energy
, Glucose
used by plants for growth and as an energy source for other organisms (Sugar)
Producers
Capture energy from the sun (e.g., plants)
Consumers
Obtain energy by eating producers or other consumers (e.g., animals)
Break down dead organisms, recycling energy and nutrients
Autotrophs
Organisms that cannot produce their own food and must consume other organisms for
energy.
Hederatrophs
Herbivores
Eat plants (e.g., cows, rabbits)
Carnivores
Eat other animals (e.g., lions, hawks)
Omnivores
Eat both plants and animals (e.g., humans, bears)
Decomposers
Break down dead organisms and recycle nutrients (e.g., fungi, bacteria)
Cellular Respiration
Breaks down glucose obtained from food to release energy (ATP)
Photosynthesis equation
6CO2 + 6H2O+ light energy → C6H12O6+6O2
Photosynthesis
the process by which plants use sunlight and chlorophyll to make food.
The process of photosynthesis primarily occurs in the
