Answer:
True.
Explanation:
Antibiotics may be defined as the chemicals that are required to stop the growth and kill the other living organism. These antibiotics have been developed against bacteria, fungi and microorganisms.
The excess use of the antibiotics leads to the development of the resistant strain against that particular antibiotic. People should not overuse or misuse the antibiotics as they may become resistant and antibiotics will not effect the pathogens of that individual organism.
Thus, the correct answer is option (a).
Answer:
tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres
Explanation:
En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.
It is important to protect biodiversity because it is the key to a sustainable and productive ecosystem. Biodiversity enables most, if not all, of the niches of an ecosystem to be filled. It also serves to protect the food web within the ecosystem, for the higher the biodiversity the lower the effects of removing or changing a species.
The correct answer is A. Density-dependent population regulation an intrinsic characteristic of population growth.
Explanation
Density-dependent population regulation includes factors such as diseases, predation, or competence that limit the growth of a population depending on the size of it (density). In the case presented, predation is the factor that affects the shrimp population because more boats and more shrimp imply more predation from humans. Additionally, this excessive predation limits the growth of the shrimp population and causes the depletion of shrimp over time. According to the above, the correct answer is A. Density-dependent population regulation an intrinsic characteristic of population growth.
