Earth's energy budget

Distribution of energy received from the Sun.

Cellular energy

Energy stored in ATP for cellular functions.

Earth's energy budget

Distribution of energy received from the Sun.

Cellular energy

Energy stored in ATP for cellular functions.

Mitochondria

Cell organelles where ATP is produced.

Solar energy

Energy from the Sun used by plants.

Chloroplasts

Plant organelles that perform photosynthesis.

Chlorophyll

Pigment that absorbs light for photosynthesis.

Photosynthesis

Process converting light energy into chemical energy.

Cellular respiration

Conversion of glucose into ATP, CO2, and water.

ATP

Adenosine triphosphate; energy currency of cells.

Chemical reactions

Processes requiring ATP to sustain cellular life.

Glucose

Sugar used as energy source in respiration.

Carbon dioxide

Gas produced during cellular respiration.

Oxygen

Gas produced during photosynthesis.

Carotenoids

Accessory pigments reflecting yellow to red light.

Xanthophylls

Pigments reflecting yellow/brown light in leaves.

Light spectrum

Range of light colors absorbed by plants.

Energy conversion

Process of changing light energy to chemical energy.

Consumers

Organisms obtaining energy by consuming others.

Dinosaur extinction

Event caused by asteroid blocking sunlight.

Photosynthesis equation

CO2 + H2O + light energy → glucose + O2.

Energy dependency

Life on Earth relies on solar energy.

Chlorophyll absorption

Absorbs blue and red light, reflects green.

Seasonal leaf color change

Chlorophyll breakdown reveals other pigments.

Photosynthesis and respiration connection

Products of one process are reactants of the other.
