What would happen to the growth curve if a pollutant were introduced into this environment?
Answer Expert Verified. If a pollutant or a new predator were introduced into an environment, then a standard exponential growth curve would be less “sharply” bent, and would curve out more away from the y-axis.
How does predation affect population growth?
They grow more slowly, reproduce less, and populations decline. As predator populations increase, they put greater strain on the prey populations and act as a top-down control, pushing them toward a state of decline. Thus both availability of resources and predation pressure affect the size of prey populations.
What happens when predator population becomes more efficient?
The more efficient the predator, the more easy way they hunt down the prey. Organisms that experience high mortality compensate by producing lots of young.
What is the relationship between predator and prey in an ecosystem?
A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Why are predator/prey relationships important to ecosystems?
