Biomagnification .
a.
causes a 90% loss of synergy higher on the food chain
b.
is caused by the ecological succession from a disturbed area to a climax community
c.
is introduced into an ecosystem through nonpoint pollution sources
d.
happens when an increased concentration of a substance accumulates in body tissues
e.
is the transportation of pollution from one ecosystem to another

d. happens when an increased concentration of a substance accumulates in body tissues

Explanation:

Biomagnification (also called amplification) causes the increased concentration of a substance(usually toxin) in a higher level of the food chain. The substance usually hard to break down, making it accumulate in the body tissue. The accumulation will get worse on higher-level food chains as they consume a lot of lower-level organisms. We can find very high levels of mercury from shark, albacore or other high-level carnivores. Trout and tuna also have a high-level of mercury because of the pollution. On the lower level, salmon have really low mercury concentration.

to answer your question:

f(x)= a^x.  if x=0, f(x)=1  if x=1, f(x)=a  if x=1, f(x)=a^a

answer: no

explanation:

i thought it would be hard. yeah it took a little while to get used to but in all you will be fine. just do your work and stay out of drama.
