We think of termites as insects that eat wood. However, termites cannot digest the wood and rely on a variety of eukaryotic and
prokaryotic gut microbes to digest cellulose. Without the microbes, the termites will still ingest wood but will starve. This, then, is an example of a(n); obligate mutualism. obligate antagonism. facultative mutualism. facultative antagonism. None of the answer options is correct.
Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.
Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.
So, termites are mutualistic related to protozoans and showing obligate mutualism.
During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle. ... In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.
3. any trait that confers even a small increase in the probability that its possessor will survive and reproduce will be strongly favored and will spread through the population.
Explanation:
Natural selection is a nonrandom process by which biological traits become more or less common in a population as a function of the differential reproduction of their bearers of differences in the rate of survival.
Natural selection can act on any heritable phenotypic trait and operate among any entities that reproduce, show inheritance of their characteristics from one generation to the next, and vary in fitness.
Natural selection is the machine that drives evolution. It also explains adaptation.
