Vocabulary (Biology)

Energy The ability to work
Photosynthesis A chemical process that changes carbon dioxide and water into carbohydrates
Producers Photosynthetic organisms produce molecules, which have energy in the chemical bonds that hold them together
Biomass Bio= Living; Mass= Matter Organic matter in an ecosystem
Autotroph Cells that make/produce their own food, they are also called self-feeders. Auto= Self; Troph= Food
Consumer Organisms that eat other organisms Ex. Cow eats grass
Heterotroph Hetero= Different Eating different foods Ex. Cow eats grass and dandelions
Herbivores Animals that only eat plants
Primary Consumers First level consumers Ex. Deer, Mice, Rabbits
Secondary Consumers Organisms that eat the consumer that eat the producer Ex. Wolves, Spiders, Snakes, Hawks
Carnivores Animals that eat meat
Tertiary Consumers Organisms that eat secondary consumers Ex. Sharks, Pelicans, Polar Bear, Barracudas (Killer Fish), and Orcas.
Omnivores Eat both plants and animals Ex. Humans, Some Monkeys/ Gorillas, etc.
Decomposers Organisms that eat other organisms' body when decomposing
Photosynthesis When plants use sunlight to convert carbon dioxide and water into sugar
Cellular Respiration Chemical process that uses oxygen to make chemical energy stored in organic molecules
Trophic Level Feeding Level in an Ecosystem
Food Chain A way of food that transfers from one trophic level to another
Detrius Waste and remains of dead organisms
Food Web A pattern of feeding organisms in different ways
Primary Productivity Rate at which an ecosystem build biomass
Energy Pyramid Diagram showing energy loss in one trophic level to the next
Biomass Pyramid Diagram showing biomass in each trophic level
Pyramid Of Numbers Representation of each organism on each trophic level
Kinetic Energy Energy of motion
Calorie Amount of energy required to raise tempeture
Potential Energy Energy stored due to an objects situation
Thermal Energy Total amount of energy moving around in random movement of atoms and molecules in the same matter
Chemical Energy Able to do work due to the number of atoms within molecules
ATP (Definition and Diagram) Main energy source used for most of their work
Mitochondria The powerhouse of the cell
Aerobic Requiring Oxygen
Eletron Transpot Chain Electron carriers that transfer electrons and release energy during cellular respiration
Metabolism All of the cells chemical process
Glycolysis The splitting of half of a glucose molecule
Krebs Cycle The stage of cellular respiration
ATP Synthase Protein structure in cell mitochondria that uses energy to convert ADP to ATP
Fermentation Cellular process of making ATP without oxygen
Anaerobic Without oxygen
Chloroplast This is found in plant cells and it's were photosynthesis is made
Chlorophyll The pigment that turns chloroplast in a green color
Stroma Thick fluid containing the inner membrane of a chloroplast
Thylakoid Disk- shaped sac in the stroma in the chloroplast, this is were light reactions of photosynthesis happens
Light Reactions Chemical reaction that convert the suns energy into a chemical energy
Calvin Cycle Cycle in plants that makes sugar from carbon dioxide
Wavelenght Distance between adjacent waves
Electromagnetic Spectrum Many types of electromagnetic energy from gamma waves to radio waves
Pigment Determines the substances color
Paper Chromatorgraphy Observing different pigments in a material
Photosystem A cluster of chlorophyll and other molecules in a thylakoid
