On a trip to a wildlife sanctuary, nathan found a piece of rotting log. he took a sample from the log to examine in his laboratory. the organism he found was eukaryotic and could not photosynthesize. it also had a cell wall. what type of organism was most likely feeding on this sample?

Fungi

Fungi is a group of organisms belonging to kingdom Fungi. These are eukaryotic organisms. They are saprophtic organisms, which means they drive their food and nourishment by decaying dead and decaying organisms. They cannot synthesize their own food by photosynthesis as they do not possess pigment chlorophyll like plants, which traps sunlight energy for photosynthesis. The cell wall of fungi is made up of chitin.

The organism feeding on the wooden log is fungus. They are able to degrade lignin component of the wood into simpler compound, which is used as a source of nourishment.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
