Question

the population of bacteria grew exponentially, roughly doubling every 30 minutes, for around 15 hours. but after that, growth slowed and then stopped. bacterial population these pictures show the petri dish of bacteria at three points in time. which of the following are the most likely reasons that the population of bacteria stopped growing? select two. the population consumed all the available food. the population decided it was large enough and chose to stop reproducing. bacteria emigrated from the population at the same rate that new bacteria were produced by reproduction. the population did not have more space to grow

Explanation:

Bacteria growth is limited by resources like food and space. When food is exhausted or space is insufficient, growth stops. Bacteria don't make conscious decisions to stop reproducing. Emigration - reproduction balance is less likely to be the main cause here as it is a closed - system scenario (Petri dish) with no indication of emigration.

Answer:

The population consumed all the available food.
The population did not have more space to grow.
