Organisms that interact serve as agents of _________ on one another. This results in __________. which is the process by which species evolve adaptations to one another.
To review:
The given blank space in the statement, “organisms that interact serve as agents of _______on one another. This results in ________, which is the process by which species evolve adaptations to one another.”
Introduction:
An ecosystem comprises of flora and fauna with their numerous species, which live in harmony. These species interact with each other from time-to-time, either within the same species or between species. These interactions may prove beneficial to some and may harm others.
Explanation of Solution
Despite the fact that species interaction may not always be beneficial for all the species, it does benefit the ecosystem as a whole. The species usually compete for food, space, and mating. The organisms that prove to be better than the others pass on their genes to future generations. The better traits tend to pass on while the defective ones get perished. Thus, they serve as agents of natural selection.
For example, a predator attacks a weak prey while leaving the one that is beyond its capability to catch. With time, the predator may acquire more fierce traits while the prey, which is spared, may increase its population by breeding. Thus, both the species help each other in adapting to their respective traits. This process is known as coevolution.
Organisms that interact serve as agents of natural selection on one another. This results in coevolution, which is the process by which species evolve adaptations to one another.

- Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.arrow_forwardSloth moths live in the fur of the sloth. This is an example of _______ (answer choices: predation, commensalism, parasitism, mutualism)arrow_forwardOrganisms rely on other organisms either directly or indirectly for their survival. This is one of the fundamental tenets of ecology (more about ecology later). Organisms do not live in isolation. How is symbiosis important in marine habitats?arrow_forward
- Lean mice (+/+) were reared so they had microbe-free guts. Two groups of lean mice were injected, one with fecal material from obese mice (ob / o * b) and the other with fecal material from other lean mice. Both groups of mice were fed the same food. Their food intake and their gain in body weight were measured. This study is an example of which kind(s) of scientific method used in ecology?

- The golden jackal is an organism in nature that follows a tiger to feed on leftovers from the tiger's kills. The tiger is unaffected by the golden jackal, while the golden jackal benefits by getting food from leftovers.
