Question

ecosystems and their resources are finite. eventually, populations run out of food, space, or some other resource they need to continue growing. so there is a maximum number of individuals within a population that an ecosystem can support. this maximum number is the ecosystems carrying capacity. bacterial population complete the sentence. based on the graph, the petri dishs approximate carrying capacity for bacteria was billion.

Explanation:

Step1: Identify the plateau on the graph

The population size stops increasing and levels - off at a certain value. This value represents the carrying capacity.

Step2: Read the value from the y - axis

Looking at the y - axis (Population size in billions), the value at which the population plateaus is 17 billion.

Answer:

17
