Question

bottleneck effect
a bottleneck effect occurs when a random event (like a tornado, drought, or other natural disaster) wipes out a large chunk of the population. the population gets smaller, just like the neck of a bottle gets smaller.

1. how many different organisms are there before the tornado?
2. how many different organisms are there after the tornado?
3. how do natural disasters affect biodiversity?

Explanation:

1. By counting the distinct - shaped organisms in the 'Before' image, we can determine the initial number. There are 10 different organisms before the tornado.
2. Counting the distinct - shaped organisms in the 'After' image shows that there are 6 different organisms after the tornado.
3. Natural disasters like tornadoes can cause the bottleneck effect. They reduce the population size and genetic diversity. Many organisms may be killed, leading to a decrease in the number of different species or types of organisms present. This reduces biodiversity as fewer genetic variations and species are left in the population.

Answer:

1. 10
2. 6
3. Natural disasters can cause the bottleneck effect, reducing the population size and genetic diversity. Many organisms are killed, decreasing the number of different species or types of organisms, thus reducing biodiversity.
