What happens to a population when its size is equal to the carrying capacity?
a. Its size fluctuates wildly.
b. It increases in size.
c. Its size stays steady.
d. It decreases in size.
Answers
Answer:
C
Explanation:
When a population reachs its carrying capacity it will slow down and become steady due to the population reaching its limit on food, water, etc. and they can only feed so many.
When population size is equal to the carrying capacity then "Its size stays steady".
What is population ?A population means the total number of individuals who cohabit in a certain area.
What is steady-state?A biofilm that exhibits no net growth or degradation over time is usually referred to as a steady-state biofilm.
A population might slow down and stabilize once it reaches it's own carrying capacity since it will no longer be able to consume as much food, water, and other resources.
Therefore, the correct answer will be option (c)

a mass extinctions is
Answers
Answer:
Mass extinction is when biodiversity or species in a living habitat decreases to about three-fourths of its original number or to none. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Mass extinctions are usually associated with organisms that are macroscopic rather than microscopic. Examples of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.
