What are at least three ways to prevent soil erosion?

Three ways to prevent soil erosion:
1)Gardening-Plant trees and shrubs because it will provide shade and shelter for the soil while the roots will help prevent the water from washing it away.
2)Water your soil-It is good to water your soil, but do not drown it, especially during the dry months. Over watering soil will wash it away and also degrade it.
3)Have high grass-Plant patches of high grass that is at least three inches high. The grass will promote retention of water in the soil.

Describe 3 abiotic factors that could affect biotic potential (population growth) and how they would affect it

Three abiotic factors that affect population growth:
1)rainfall-Rainfall is a source of water and is what water the plants and grass. So if there wasn't a lot of rainfall in one year than the animals might not have a lot to eat and drink, which ended up in more deaths than usual.
2)the weather-Depending on the weather, whether its hot or cold, could determine a population life. Different population have different abilities to adapt to the changes in the weather. It is called resilience.
3)disease-If there is a disease going around, then more animals in a population would die, and the population would decrease.

Should re-wilding species be keystone species? How could re-wilding be made successful?

Yes, I think rewilding species be keystone species, such as the beaver, the lion, the horse. If not, than the keystone species could be wipe out and become extinct. These keystone species are important to the environment and to us. Rewilding can be made successful by releasing the animals caged in the zoos, or to simply stop hunting them.

Describe why sampling is important to the study of populations

Sampling is important to the study of populations because we get to find out what is true about the population. To test the sample, you need a representative of the population. It would be better if the representation was a random selection. We could find how many are in the population and where it has traveled.

Which biome would you most like to visit? Why?

I would like to visit the tundra biome because its the coldest out of all the biome, and I like the cold! Also because it has short summers and the temperatures during the summer goes only as high as 50 degrees Fahrenheit.

What surprised you most about the waste we create over a lifetime?

What surprised me the most about the waste we created over the years is that we have a lot of wastes. Every year, thousands of things are made, such as hamburgers, hot dogs, milk cartons, and diapers. When we buy these products, we don't think how it was made or what the making of it does to the environment.

What can diet tell us about the organisms that are eating? Give three examples

If we look at an animal's poop, basically it can tell us a lot of things. For one thing it can tell us what kind of animal it just ate and where it ate it(the environment). A second thing we can learn by looking at the poop is tell whether or not the animal is healthy or sick. A third thing we can determine from the poop is what type of environment it likes to hunt in and what it likes to eat. For example, eagles like it eat a lot of different animals: rabbits, lizards, frogs, snakes, squirrels, other birds and even small dogs. Eagles can find their prey in the water, the grass, or even the tree, and we can know all that just by looking at its diet/poop.

Would you consider becoming a vegetarian or vegan? Why or why not?

I don't think I could ever be a vegetarian or a vegan because I need meat in my life! I eat meat like at every meal, and I would miss it if I stopped eating it. I love vegetables, but I also love meat. In and Out rocks!!!

Where humans are having the most impact and why

Humans have many activities that affects animals and their habitats. With George Bank Fishery, over fishing occurred because the world demands increased. Humans are also responsible for the introduction of foreign species that invade the environment, sometimes in dramatic fashion. For example, the comb jellies from North America have all but eliminated commercial fishing in the black sea. (the left is a picture of a huge comb jelly.) They eat microscopic plankton thereby depriving fish of their food supply. I think humans are having the most impact concerning animal's homes and food supply that will eventually lead to their extinction.

What is order, randomness, complexity and examples of it

Order is when you have rules that produce patterns or an order system. Randomness is out of order. There is no pattern and no rules. Complexity is complicated, full of entanglements, and is not simple. An example of order is the law. An example of randomness is playing the slot machines. An example of complexity is to find a needle in a haystack.

What I learned and what I want to learn

In Mr. Chen's class, I learned about the clouds and that they are classified by their shape and their height. I also learned that there are three types of volcanoes and and the boundaries. In addition I learned all about the renewable energy. I would like to learn how we can save the environment.
