Forkbirds

===**In this experiment, we had three different types of forkbirds. The three different types of forkbirds were either 4-Tined, 2-Tined, or 1- Tined. Starting off for Generation 1, there were 95 2-Tined forkbirds and no forkbirds that were either 1-Tined or 4-Tined. In Generation 5, the 2-Tined forkbirds decreased to 57 forkbirds. The 1-Tined forkbirds increased by 11 and the 4-Tined forkbirds also increased but by 28. And at the end in Generation 10, the 2-Tined forkbirds they population decreased even more an this time to 34 in total population. For the 1-Tined forkbirds they increased by 7 and for the 4-Tined forkbirds they increased by to 46 in total population. **===
 * 1) Describe what happened to each type of fork bird over time.

2. Which fork bird was the most successful? Use your data to support your answer. === The forkbird that was the most successful type of forkbird was the 4-Tined forkbird. This one was the most successful because it started off at zero and always increased. The reason that the 1-Tined forkbirds weren't the most successful was because in Generation 10, for the 4-Tined forkbird there were 46 forkbirds in total and for the 1-Tined forkbirds it was 18. The difference between these two populations are very different. So to conclude, the most successful forkbird was the 4-Tined forkbird. ===

 //3. Battling Beaks// simulates the idea of ** NATURAL SELECTION. **Based on what you did in class, your data and questions 1 and 2, what do you suppose natural selection?


 *  I think that natural selection is when an organism adapts to its environment. This includes getting used to the weather, the surroundings,the type of food and the conditions of the environment in general. For the forkbirds, they had to get used to what they had whether it had 4,2, or one Tine. The amount of tines the forkbird has will affect its way of living like the amount of food. If the forkbird is unable to survive it won't be able to breed which causes the kind of forkbird's population to decrease. The population decreases because of how well the forkbird adapts to the environment. **

4. As a result of heavy rains, the major food source for fork birds is now blueberries. After many generations, how many types of fork birds do you think there will be? What will the fork birds look like? Explain your answer.

=

 *  I think that there will be one type of forkbird after the change in the major food source. The one type of forkbird that will survive will be the 4-Tined forkbird. The other types of forkbirds (2-Tined and 1-Tined) will slowly disappear because of the effect of the change of the food source. I think that they will disappear because all the 2-Tined and 1-Tined forkbird will have to adapt to the environment's new major food source. Another reason is with all this new rain, the forkbirds will need to adapt to the new climate which may affect how much food they find and eat. And if the 2-Tined and 1-Tined forkbird aren't able to adapt to the condition the population will decrease because the forkbird won't have food to eat which will cause it to die. For example, if a snake's main pray is a mouse and suddenly, all the rats in it's environment are exterminated then the snake will have to find something else to eat and if it doesn't the population will decrease. Nature is a delicate balance and if it is messed with all organisms suffer. In this case all the 2-Tined and 1-Tined forkbirds will suffer. **======

5. The cheetah, an extremely fast and efficient hunter, is an endangered species. The few cheetahs alive today show very little variation. How does this help to explain why cheetahs are on the verge of becoming extinct?
 *  The cheetah is on the verge of extinction because there's only ONE type of cheetah. And if there's one type of cheetah and if any change occurs in its natural selection the whole species of cheetahs will suffer. This situation varies to lets say frogs. There are 4,000 different types of frogs. So if one type extincts because of a change in its environment then there will be 3,999 types. If one species dies, it effects all the frogs by very little. But on the other hand if the cheetahs dies the animal dies along with it. There are no other species to carry on the name of the cheetah. Which is why if the cheetah is extinct then the animal is gone forever.This situation is similar to the wholly mammoth. When it got extincted, the mammoth's name died along with it. That is why all animals that don't have different types must be cared for more than others with different types. **
