Based on natural selection and the data provided, it was observed that birds with the spoon beak type were most successful in obtaining food both before and after the drought.
What is natural selection?
Natural selection is the process by which organisms that are better suited for survival in an environment are selected to survive and reproduce.
Natural selection depends on variation among species.
Considering the table:
1. There was variation in the beak type of the birds.
2. Before the drought, the toothpick beak type and spoon beak type gathered the most most food.
3. After the terrible drought, the spoon beak type was most successful.
4. If the drought conditions continues;
- The toothpick beak type will decrease
- The spoon beak type will stay the same
- the fork beak type will decrease
- the knife beak type will decrease
5. The process by which If the birds become isolated from other populations they become a completely different species is called evolution.
6. Having repeated trials helps the reduce the possibility of chance occurrence in the results obtained.
7. The class average data will give a truer picture of the effects of drought on bird feeding because of the larger number of sample.
Also, it will help to eliminate individual group errors and identify outliers.
8. There were no significant differences between your trials for the spoon beak.
