Question

of 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: Understand Carrying Capacity

Carrying capacity is the maximum population an ecosystem (here, Petri dish) can support, so we look for the plateau in the graph.

Step2: Analyze the Graph

The graph of bacterial population over time plateaus (stabilizes) at a population size. Looking at the y - axis (population in billions) and the plateaued points, they are around 17 (or visually, the horizontal line of points after growth stabilizes at approximately 17 billion).

Answer:

17
