Duckweed Growth Experiment

Introduction In ecological succession plant life starts and changes over time in a progressive way and is a process that can be observed along coastal regions all over the world. Primary succession often begins with small prokaryotes and protist that get washed up on shore. Lichens and

Plankton Activity Postlab 1) Apply 2.5: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. Explain how the abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton population reaches its carrying capacity (determined by availability of other resources besides nitrogen, [DO] levels, predation etc.),

According to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).

Environmental Science and Sustainability (SCI201 -1504A -07) Instructor: Trena Woolridge Unit 4- Discussion Board Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment.

If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle

When it comes to banning a book, many different criteria have to be met. With books in high school, it can be very controversial with parents as to which books need to be banned. In Schools, books are banned from things like foul language, sexual content, of just speaking about things parents or the school board may not like. In this book Milkweed by Jerry Spinelli, it is being banned because it is a story about a little Jewish boy and how it was during the Holocaust. Dean Schneider on Bookpage.com says, “Underlying this story of war and the Holocaust is a young boy’s search for a name and something to believe in.”

Words can tear you down Do you see people being hurtful? The novel Milkweed along with personal experiences of my own, I have come to realise that words can have a powerful affect on your life. Words have the ability to lift people up, tear people down, and define a person’s character. Words can sometimes reinforce a person’s positivity when used in the right way. Sportsmanship from an opposing team when my baseball team loses has lifted me up even when I felt like I played my worst.

ews Sliding Under Obstacles in the Will of Survival Lice. There is an abundance of lice in your head, and there are more eggs than lice. You get used to it. You’re starving, beaten, and dying of disease. These are just a few things you have to deal with.

Milkweed was wrote by Jerry Spinelli. This is a story of an orphan in 1930s Poland who is very naïve and knows nothing. Not who he is, who other people are, nothing of the world around him. He knows only that he is small and fast and able to snatch food right from under the noses of the people it belongs to. He is eventually taken in by a gang of orphan kids, and becomes the special ward of one in particular, Uri.

The fixed nitrogen not only changed America’s agriculture, but also changed the earth’s natural cycle. Furthermore, the soil fertility shifted from the reliance on the sun’s energy to the reliance on fossil fuel. These changes causes global warming and pollution. This

Magic Grow Capsules are made of gelatin capsules. Gelatin Capsules can be regular or vegetarian. The regular gelatin capsules are made from gelatin. Gelatin comes from a substance called collagen. Collagen comes from animal skin and bones.

Based on these results, it is hypothesized that if the amount of topsoil increases by 25% then plant growth increases because topsoil contains essential nutrients required for proper plant

Introduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.

They also help water move from the soil to the atmosphere through a process called transpiration. Plants not only supply us with food, but with other provisions such as wood products, fibers, oils, resins, coal, and petroleum. They also provide us with raw material needed to make shelter, clothing, medicines, and fuels. It’s also a fact that one quarter of the medicines we use are derived from plants; and that 4 out of 5 people in this world rely on plants for primary health care. Importance of Plants Plants are everywhere.
