Hi!
Energy will flow through an ecosystem in one <em>direction, </em>from the sun or inorganic compounds to<em> autotrophs </em>and then to various <em>heterotrophs. </em>
The energy flow in an area will be delivering light energy to <em>autotrophs</em>, which make their food from the energy the sun produces.
The energy flow also delivers energy via inorganic compounds to <em>heterotrophs</em>, which do not make their own food.
Hopefully, this helps! =)
Proteins are made up of monomer units called amino acids
He first divided all living organisms in 2 groups
Animal or Plant
He then put these into subgroups
Animal subgroups: land, water, air
Plant subgroups, small medium or large
Not a very specific approach to taxonomy but it was used for well over 100 years
The term used to describe an organic cofactor is that this common chemistry allow cells to use a small set of metabolic intermediates to carry chemical groups between different reactions. These group-transfer intermediates are the loosenly-bound organic cofactors, often called coenzymes.
