Nutrition
Autotrophic 
Nutrition
De?nition: Organisms 
synthesize their own food 
from simple substances.
Examples: Green 
plants and some 
bacteria.
Photosynthesis process: 
Conversion of CO2 
and water into 
carbohydrates.
Heterotrophic 
Nutrition
De?nition: Organisms 
depend on other 
organisms for food.
Examples: Animals, fungi.
Types: 
Saprophytic: 
Decomposers 
like fungi.
Parasitic: Organisms 
like ticks, lice.
Respiration
Aerobic 
Respiration
De?nition: Breakdown 
of glucose in the 
presence of oxygen.
Location: Mitochondria.
Products: CO2, 
water, and energy.
Anaerobic 
Respiration
De?nition: Breakdown 
of glucose 
without oxygen.
Examples: Yeast 
(produces ethanol and CO2), 
muscles (produces lactic acid).
Heart and Blood Vessels: 
Transport oxygen, nutrients, 
and waste.
Transportation
In Human 
Beings
Double Circulation: 
Blood passes twice 
through the heart.
In 
Plants
Xylem: Transports 
water and minerals.
Phloem: Transports 
food and other 
substances.
Excretion
In Human 
Beings
Nephrons: The functional 
units of the kidneys.
In 
Plants
Excrete gases 
(O2, CO2) via stomata.
Waste stored in 
vacuoles or expelled 
through falling leaves.
