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

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.
