Question

49.A population of pheasants grew until it reached the maximum carrying capacity of an ecosystem. Then, the pheasants' food supply increased. As a result, the carrying capacity of the pheasants' habitat changed.
Which graph could represent the history of the pheasant population?
50.The graph below shows changes in the world population over time.

What term can be used to describe this graph? A. negative exponential growth B. negative linear growth C. positive linear growth D. positive exponential growth .
someone please help asap

Answer 1

For the pheasant question, it would be the top right graph as this shows an increase, then a further increase in the population of pheasants.

For the population of the world graph, it shows positive exponential growth as it is a large amount of growth within a small time period

Answer 2

Answer: First part- The first row graph on the right hand side depicts the history of pheasant population.

Second part -The graph that changes in the world population over time is depicted as positive exponential growth

Explanation:

First question: The history of the pheasant population is depicted in graph given below.

Initially the population of pheasants grew till it reached maximum carrying capacity of ecosystem.  

The pheasants food supply increased. As a results the carrying   capacity of the pheasants habitat changed.

Second question:  The graph that changes in the world population over time is depicted as positive exponential growth.

Negative exponential distribution is process in which events occur continuously and independently at constant average rate. It is represented in graph as  

Negative linear distribution is the inverse relation between the two variables as depicted by graph.

Positive linear distribution is the direct relation between the two variables as depicted by graph.

Positive exponential distribution is process in which events occur independently at fixed intervals  and at constant average rate.

On the basis of the above explanation is:  

First part- The first row graph on the right hand side depicts the history of pheasant population.

Second part -The graph that changes in the world population over time is depicted as positive  exponential growth.
