Answer:
a virus, because it requires a host cell to reproduce
Explanation:
- a bacterium, because it is contagious
-
a fungus, because it infects livestock
-
a protist, because it is microscopic
-
a virus, because it requires a host cell to reproduce
The correct answer would be <u>a virus because a virus is the only microbe that cannot reproduce on its own without a host</u>. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.
<u>In lytic cycle</u>, the virus utilizes the genome system of the host to produce more viruses that eventually leave or lyses the host to become independent viral particles, killing the host in the process.
<u>In lysogenic cycle</u>, the virus inserts its genome into that of the host and uses the host's replication machinery to replicate its genome. The virus then waits for the defense mechanism of the host to become weakened before multiplying and lysing the host.
If there is an increase in coronavirus that means that the animals that eat the producers will be less which causes more producers

Answer:
Option C, Estuary
Explanation:
<em><u>An estuary is a geographical entity where the salty water of ocean mixes with fresh water of river. The resulting water is known as brackish water. The brackish water is not as salty as that of ocean and also the salinity level of water rise and fall regularly.</u></em>
<em><u /></em>
<em><u>Thus, an organism that is able to live in both salty water and fresh water environment can survive in an estuary.</u></em>
<em><u /></em>
<em><u>Hence, option C is correct</u></em>
