Answer:
B) Predation and C) Decomposition
Explanation:
Fungi predation refers to fungi that derive some of their nutrients from trapping and eating microscopic animals. Some species trap nematodes which are normally present in the soil while others prey on ameoba.
Fungi decomposition occurs when organic matter is broken down by releasing enzymes to break down the decaying material, after which the nutrients in the the decaying material is absorbed.
Option A. troposphere
Good luck
Jellyfish should reproduce sexually if genetic variation is needed in order to survive in the change in environment.
Jellyfish should reproduce sexually if genetic variation is needed by the organism leading to more adaptations to the natural environment. There is no variation between offspring in asexual reproduction.
It involves single parent not two parents so their chances of survival against change of environment while on the other hand, offspring produced from sexual reproduction having variations that leads to higher chance of survival.

Hi
Mutations are responsible for increasing the antibiotic resistance of some bacterial strains.
As we know that antibiotics are the drugs that target specific strain or type of bacteria, and kill them. These are designed against specific disease causing gene of that bacteria strain. However, as the genome of bacteria is very small in size, and bacteria undergo hundreds of multiplication events in very small span of time. Therefore, upon replicating, there occur chances of mutations in genetic sequence of bacteria.
When the genetic sequence of bacteria is changed even by one base, the drug wont be able to target and kill that strain of bacteria. And researchers need to design new antibiotic against new strains of bacteria.
Antibiotics resistance has become huge issue across the world as it takes alot of time (years) to design and approve an antibiotic.
Hope it help!
