Ecosystems on the Brink
A: List the major ideas, concepts or key points- point by point
• To keep jellyfish, fungi and other creatures from overtaking healthy habitats, scientists are exploring food webs and tipping points.
• Scientist dropped 12 largemouth bass into the water, that was measure every five minutes, 24 hours a day.
• Process repeated in 2009.
• Peter Lake changed dramatically, the lake abounded in fathead minnows, pumpkinseeds and other small fish.
• Animals graze on algae, the lake water became clearer.
• Peter Lake’s food web flipped, to a new one.
• Ecologists have turned food webs into mathematical models.
• Most food webs, consist of many weak links and few strong ones.
• Two species are strongly linked such as a predator devouring huge numbers of a single prey.
• Peter Lake was the first time they had put the early-warning system to a test in a natural ecosystem.
• performed daily recordings of the zooplanktons, phytoplanktons and fishes in the water. There was a change.
• “CARPENTER IS DEVELOPING AN EARLY- WARNING SYSTEM THAT CAN REVEAL WHEN A FOOD WEB IS ABOUT TO FLIP AND OFFER GUIDANCE ABOUT HOW TO PULL IT BACK FROM THE BRINK.”
B: Summarize the AUTHOR’s main point or idea- at LEAST 1-2 paragraphs
Changes in the food web can be very, very difficult to change back. Dropping largemouth bass in the waters of Peter lake has caused a change dramatically. The lake abounded in fathead minnows, pumpkinseeds and other small fish. Water fleas and other tiny animals that the small fish once devoured were now free to flourish. The food web has been flipped, creating a new one. Around the world there has been many of this cases, where food webs changed. Some examples are the jelly fish in Namibia, that now control their waters. Other could it be the removing of gray wolves from Yellowstone National Park allowed a boom in elk, which dined on aspen leaves, killing many young trees. But changes in the food changes can decrease the population, and cause a collapse. Some scientist are developing a warming system that could reveal when eh food web is about to change, so they can do something before it goes pass it’s brink.
C: Write a reaction paragraph to the article stating your own thoughts on the topic, using specific citations from the article to support your views
Food web is more than just the relationship and energy flow of the interaction of the organisms. Is the way to shows us how things work within, their relationship and reason why they flow the way they do. After changes are made there’s not coming back (it would be too difficult.) I was surprised to know that we can makes those changes, in both way. We can help the food webs to go back from their originals states and to create a new one. There are many of doing it, and we are doing it. Experimenting, and finding a way. There’s hope. Because Carpenter is developing a warming system that can help us know when a food web is going to change. This way we can make a differences before it happens.
What?
Food webs are very difficult to change after the damage is done, but we are making changes in them without even noticing.

What If?
The scientist wouldn’t haven’t discovered any changed in the lake?
If they haven’t dropped any largemouth bass into the water. They wouldn’t know any changed in the water. What does it remains you of? Of the prolific afterlife of a whale, because it shows that there are thing still left to discovered.
