The symbols +, -, and o are to be used to show the results of interactions between individuals and groups of individuals in the
examples that follow. The symbol + denotes a positive interaction, - denotes a negative interaction, and o denotes where individuals are not affected by interacting. The first symbol refers to the first organism mentioned. What interactions exist between cellulose-digesting organisms in the gut of a termite and the termite?
The interaction between cellulose-digesting organism in the gut of a termite and the termite is +
Explanation:
This relationship that exists between termites and the organisms present in their gut that are capable of degrading cellulose is a relationship called mutualism. Mutualism is part of the biological interactions in which both organisms benefit from the coexistence of both. For this reason this relationship would be positive.
The food of termites is wood, but they cannot produce the enzymes they would need for degradation of the wood. Thanks to this, there are small organisms called protozoa that are found in the intestine of the termites that allow them to degrade the cellulose present in the wood, these organisms help them to degrade the cellulose that by themselves they could not do since termites do not contain the cellulose enzymes responsible for cellulose degradation .In this way TERMITES can get what they need to perform its metabolism and biological functions.
The control group is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
