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 growthb. negative linear growthc. positive linear growthd. positive exponential growth .
someone asap

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.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
