An organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other's expense; So basically, what you’ll be getting at is C, only harms another organism.
A. a tree
you can first eliminate B. and C. to make it easier to choose an answer. then you can eliminate a generator because it would turn mechanical energy into electrical energy. a tree uses photosynthesis to convert light energy into chemical energy, using the sun as a source for the light energy and turning it into food (chemical energy)
Answer:
Answer A: A key example of biotic and abiotic protagonists is the presence of rocky structures that exist in the mountains of southern Argentina (Patagonia) that thanks to them exist the ideal temperatures for the procreation of animals such as the Patagonian condor and the possibility of form nests in these rocky structures that secure their young.
Answer B:
The explanation for this is that they have populations that increase in number and have their niches realized and constant resources necessary to develop the species in this way, considering the dominant species in the area and the one that predominates, in the case of fundamental niches. , they are necessary and even obligatory niches for many populations, which if populations do not go to them, they die, extinguish, or decrease their number, that is why in the face of this reality made up of a fundamental niche since it is fundamental to persist life of the population.
Answer c:
Two key principles are: one, maintain the equilibrium, that is why one seeks to have an environmentalist position preserving nature, and two considering that we are part of that balance but that does not give us the right to break it with environmental contamination, intervention of natural food systems and many other factors.
Explanation:
The full statement is this: In 1859, Charles Darwin wrote, 'The ........................... ...... At the based of the evolutionary tree of all life is AN ORGANISM THAT IS A COMMON ANCESTOR TO ALL LIVING ORGANISMS.
In biology, evolution has to do with gradual but constant changes in the overall form of living organism. Scientists believe that all life forms came from a common ancestor; it is through the process of evolution and natural selection that primitive life forms developed into higher forms of living organisms. In short, what the statement given in the question is trying to say is that ALL LIVING ORGANISMS ARE RELATED BECAUSE THEY HAVE A COMMON ROOT (A COMMON ANCESTOR).
