taxonomic level order (phrase)

Dear King Philip Came Over For Good Soup

taxonomic level order

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Wandering albatross (kingdom, phylum, class, order)

Animalia, Chordata, Aves, Procellariiformes

sunlight

first step in most ecosystems

photosynthesis

convert light energy into chemical energy (glucose)

macromolecules (are known as the)

building blocks of life

macromolecules (definition)

Molecule containing a very large number of atoms

(4 major classes of) macromolecules

Carbohydrates, lipids, proteins, nucleic acids

carbohydrates (contain what 3 atoms in a x:y:x ratio?)

C, H, O, 1:2:1

carbohydrates (are referred to as ___)

sugars

3 types of carbohydrates

monosaccharides, disaccharides, polysaccharides

monosaccharides (basic definition)

simple sugars (carbohydrate type)

monosaccharides (function)

basic fuel molecules for living cells

monosaccharides (give 2 examples)

glucose, fructose (are 2 examples of)

disaccharides (basic definition)

2 monosaccharides linked together (carbohydrate type)

disaccharides (function)

used to transport sugars in marine plants

disaccharides (give example)

sucrose (is an example of)

sucrose (is made up of)

glucose + fructose (help make…)

polysaccharides (basic definition)

3+ polymer chains of monosaccharides (carbohydrate type)

polymers (definition)

molecules with repeating units

glycogen (definition)

multibranched carbohydrate polysaccharide of glucose, serves as energy storage in animals, fungi, bacteria

3 types of glucose polysaccharides (carbohydrates)

starches, cellulose, chitin

starches (basic definition)

glucose chains that are easily separated (polysaccharide type)

starches (function)

serve as energy storage (produced by plants, algae, microorganisms)

cellulose (basic definition)

glucose chains highly resistant to separation (polysaccharide type)

cellulose (function)

serve as structural components in cell walls

chitin (basic definition)

modified glucose chain highly resistant to separation (polysaccharide type)

chitin (function)

structural component of invertebrate exoskeleton

autotrophs (definition)

organisms that produce their own food (are called…)

heterotrophs (definition)

organisms that cannot produce their own food (are called…)

respiration (who can do it?)

autotrophs and heterotrophs (are able to do…)

photosynthesis / primary production (who can do it?)

only autotrophs (are able to do…)

photosynthesis (formula)

H2O + CO2 (low energy) → glucose + O2 (high energy)

cellular respiration (formula)

glucose + O2 (high energy) → H2O + CO2 + ATP (low energy )

respiration (simple definition)

break down organic compounds to release energy for cellular activities

primary production
