Answer:
Polar Bears feed on seals. So, polar bears and seals share a prey predator relationship. If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
Explanation:
Complete the paragraph based on this food web: Polar bears feed on seals. So, polar bears and seals share a _prey predator_.Climate change has caused ice caps to melt in colder regions where polar bears live. This change has caused them to hunt less. This situation will lead to_?extinction?_ 1 prey-predator relationship mutual relationship parasitic relationship. 2 less biomass in the quaternary level increased biomass in the quaternary level less biomass in the primary level.
If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
