Population dynamics lab activity as you complete each slide of this lab activity, fill in the population dynamics lab report with the appropriate information and data. the arctic with moutnains and the frozen sea. © 2013 thinkstock the purpose of this lab is to:
analyze graphs to determine the population size of two marine species.
explain how predation, birth, and death rates impact marine populations.
describe how biotic and abiotic factors influence marine populations.

Explanation:

a. There are gain to reproduce, if increase the number of seals, it's will increase the number of whales, because they eats the seals and become strongest to reproduce. If the seal’s birth rate goes up, the whales will benefit more. If the whale’s death rate increases, the seal’s will benefit more than the whales.

b. The more the whales capture, the fewer seals there will be. Over time, this will negatively affect both the seals and the whales.  

c. Limiting on the size of population, such as temperature, light and soil.  (abiotic factors), or biotic factors, such as competition, predation, availability of food, or ability to survive.

answer; the correct answer is chemical:
