BIO

• NUTRITION - STUDY OF NUTRIENTS IN FOOD. BIOCHEMICAL AND PHYSIOLOGICAL PROCESS
• AUTOTROPH - A PRODUCE. AN ORGANISM THAT CAN PRODUCE THEIR OWN FOOD.
• PHOTOAUTOTROPHIC NUTRITION - TAKE PLACE IN THE PRESENCE OF SUNLIGHT
• CHEMOAUTOTROPHIC NUTRITION - DONT RELY ON SUNLIGHT. OBTAIN ENERGY BY OXIDIZING INORGANIC COMPOUNDS
• HETEROTROPH - A COSUMER. CAN'T PRODUCER THEIR OWN FOOD THAT WHY THEY'RE RELYING ON OTHER ORGANISM
• PARASITIC ORGANISMS - DEPENDS ON OTHER ORGANISMS OF ITS SURVIVAL. INSIDE OTHER LIVING ORGANISM CALLED HOST AND OBTAIN FOOD FROM THEM
• SAPRAPHYTIC ORGANISMS - OBTAIN THEIR OWN FOOD FROM DEAD ORGANISM
• HOLOZOIC ORGANISM 0 RELY ON EXTERNAL FOOD SOURCES TO OBTAIN ENERGY OF NUTRIENTS. MOSTLY ON ANIMALS
• CHLORPLAST - TO CARRY OUT THE PROCESS OF PHOTSYNTHESIS
• DIGESTION - BREAKING DOWN OF FOOD INTO PARTS THAT CAN BE UTILIZED BY THE BODY
• MECHANICAL DIGESTION - BREAKING DOWN FOOD INTO SMALL PIECES AS WHEN FOOD IS CHEWED G GROUND BY THE TEETH
• CHEMICAL DIGESTION - USUALLY INVOLLVES ENYZMES IN BREAKING DOWN OF FOOD INTRO SIMPLES MOLECULS
• BULK FEEDERS - CONSUMES LARGE QUANTITIES OF FOOD AT ONCE. EX ARE SHARKS
• AUTOTROPH


  are organisms that can produce their own food, using materials from inorganic sources.
• HETEROTROPH


  an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter.
• ORGANIC COMPOUNDS


  any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
• INORGANIC COMPOUNDS


  inorganic compound is typically a chemical compound that lacks carbon-hydrogen bonds, that is, a compound that is not an organic compound.
• CONSUMER


  are living creatures that eat organisms from a different population.
• PRODUCER


  are organisms that make their own food; they are also known as autotrophs.
• SAPROPHYTIC


  are organisms that consume decaying organic matter.
• PHOTOAUTOTROPHIC NUTRITION


  light energy is used to convert simple substances to complex organic compounds.
• CHEMOAUTOTROPHIC NUTRITION


  the oxidation of inorganic compounds is used as an energy source for the conversion of simple inorganic compounds to complex

  organic compounds.
• PARASITIC ORGANISMS


  organisms live on or inside other living organisms called hosts and obtain their food from them.
• HOLOZOIC ORGANISMS


  ingest food that is mechanically broken down and is subsequently digested by enzymes produced within the organism.
• ASEXUAL REPRODUCTION


  results in new organisms formed by mitotic cell division producing offspring that are genetically similar to their parents.
• SEXUAL REPRODUCTION


  involves the fusion of gametes or sex cells from two parent organisms which are produced through meiosis.
• REPRODUCTION


  is essentially a process by which individuals produce new individuals of the same kind.
• FISSION


  occurs when a parent cell splits into two identical daughter cells of the same size.
• FRAGMENTATION


  occurs when a parent organism breaks into fragments, or pieces, and each fragment develops into a new organism.
• BUDDING


  occurs when a parent cell forms a bubble-like bud. The bud stays attached to the parent cell while it grows and develops. When the bud is fully developed, it breaks away from the parent cell and forms a new organism.
• VEGETATIVE REPRODUCTION


  occurs when new individuals are formed without the production of seeds or spores.
• EXTERNAL FERTILIZATION


  occurs in aquatic animals where the gametes are released from both the male and female animals, and the fusion takes place outside the body.
• INTERNAL FERTILIZATION


  observed among terrestrial animals, is a strategy used to prevent dehydration of the gametes on land.
• BLOOD VESSELS


  are the channels or conduits through which blood is distributed to body tissues.
• CAPILLARIES


  are tiny blood-containing structures that connect arterioles to venules. They are the smallest and most abundant form of a blood vessel in the body.
• LUNGS


  are a pair of spongy, air-filled organs located on either side of the chest.
• HEART


  pumps blood through the network of arteries and veins.
• ARTERIES


  are thick walled vessels which allow the passage of oxygenated blood, except the pulmonary artery.
• VEINS


  are thin walled vessels compared to arteries, carry non-oxygenated blood towards the heart, except for the pulmonary vein.
• BLOOD


  carry nutrients and oxygen to the cells of the body and carry away carbon dioxide and nitrogenous waste from the body cells.
