Summary Questions

                                                         Summative Summary Questions


1. Using an example, describe why a population could not increase for ever.

Because in some point if their is a lot of predators they wont be so much preys so the predators would decrease and the preys would start increasing and then the population of preys would start overpopulating the whole animal population so that's why we need predators so they can control the prey population.

2. What are the 2 factors that determine whether a population increases or decreases.

The first factor is the predators, and the second factor is the preys, because they determine the population of the whole predators. If we wouldn't have preys then the predators would starve to death because they wouldn't have anything to eat except themselves.

3. Give a reason why the human population of earth has continued to increase so much for the past hundred years?

First, because nothing eats us, we are the predators. And second, each day at least 400 babies are born, so the population is going to keep on growing and growing. In my personal opinion I think that the world is going to reach a point that the world would be completely overpopulated of humans.

Symbiosis

                                                                        Symbiosis

 In this essay I am going to explain what is Symbiosis. Symbiosis is close and often long-term interaction between two or more different biological species.The definition of symbiosis is controversial among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to any types of persistent biological interactions. Symbiotic relationships include those associations in which one organism lives on another, or where one partner lives inside the other. Symbiosis is also classified by physical attachment of the organisms, in which the organisms have bodily union is called conjuctive symbiosis. Also there is three kinds of Symbiosis; mutualism: The relationship between the flower and the bee. Commensalism: is a relationship between two species in which one species benefits while the other is not affected. And parasitism: is a relationship between to species in which one species benefits while the species it depends on, its host, is harmed. It connects to what we are learning because it connects to food webs because it relates to animals.

Food Web picture

Discussion Questions

1. Why do we (as scientists) build food webs?

I think to measure what animals eat and what are they eaten by, also to distribute the different kinds of animals to different category's. It helps a lot of scientists so they know if it is a carnivore, omnivore or herbivore.

2. Give an example of how one change might affect many other parts of an ecosystem.

Not only it affects several parts, It affects all of the parts because if one animals population, for example the mice, disappears, the hawk wont have allot of things to eat so the hawk population would start decreasing and decreasing, and then bigger animals wont have the hawks to eat so they would decrease and then so on and so fourth.

3. Give an example of how one change in La Quebrada might affect the rest of the ecosystem.

If the plant population wouldn't exist in the quebrada we wouldn't have as many diversity and different types of animals that in these days we have. And with more diversity better because more animals could come and enjoy the quebrada as a home.

Quebrada

Santiago Rodriguez
Sep 10/2014
Science P1

        For starters, we went up to the Quebrada to build quadrants, and to find measurements, plants, trees and living animals that were in the Quebrada. I had a great time learning about different plants and trees and different diversions of animals. 

        First of all I am going to talk about 3 different types of trees. First, the Prunus Serotina known as Black Cherry, the habit was a little bit wet and humid, also the tree was very tall with 7.50 m, with also lots of leaves. With the circumference of 19 cm. Then we have the other kind that is Retano liso known as Broom. The habit was clean and was next to the river so it was also humid also it wasn't so tall with 5.80 cm so we could get a really good look of it, it had very long leaves with the circumference of 16 cm. Finally we have the last one that is Fraxinus chiresis known as Ash, the habitat was dry because it wasn't near to the river but it was also really tall with 7 m but with not many leaves and with the Circumference of 30 cm.

         Now, I am going to talk about three different types of Plants. First, the Eucalyptus Globulus known as Eucalyptus, that in their surroundings were 10 of those but in the whole quadrant they were 83. Then we have the piper Artanthe known as Cordonsillo peludo, that in the surroundings they were 19 of them but in the whole quadrant they were 83. And last but not least the Tominjeo known as Rubicae, that in its surroundings had 16 of it but in the whole quadrant they were 83.

          Now I am going to tell you about the three different types of animals that we found. First is the Blattodea known as cockroach and our evidence of seeing it was that it was collecting food also It was big and brown. Then we have the Lumbricus terrestris known as worm, we saw it dragging it self to eat leaves it was really slimy  and moved really slow. And the last animal that we saw was a Limentis archipus known as a butterfly we saw it near a group of flowers that were purple it was really nice because it was black with orange spots.

          For conclusion I think we had a really good chance to experience different trees, animals and plants witch leads us to get a better idea of how is our nature.

Mapping Madness

E
Section #1
I chose section 1 because it had trees that covered the area with a lot of shade and had rocks and a near by river that passed through the rocks that prevented a cold nice river.


Section #2
Also i chose section 2 because it has open spaces and a bunch of trees surrounding the place with shade  and comfort also it has a river crossing the space with big rocks around it.

Section #3
Also I chose section 3 because its a closed section burt it provides a lot of shade and has a nice habitat for something to live in.

debrief

          I think my results were really good because It was like I  expected it with all the measurements and details. And my hypothesis was proved because my biggest plant measured 6 cm and then the other ones measured lower, and I don't think anything went wrong because my results and my hypothesis were proved. Also if I would do another project I think I would of done an animal or another living thing.

Dead or Alive?

Dead or alive?

           In the trailer they showed zombies but the question is is he dead or alive? Witch leads us to the RINGER rules, a zombie has a Respiratory system that is oxygen and Co2 witch means that they can breath. Also a zombie has senses a easy way of Irritation and it needs food to survive that leads to Nutrition. In a weird way zombies can Reproduct by contaiging people witch makes a bigger population.
