What would be the potential environmental effects of cutting down 100 acres of forest in order to build a new shopping mall? Make sure to focus on environmental and not economic effects.

Answers

1. It increases carbon dioxide in the atmosphere. 
Plants and trees play a vital role in keeping the planet habitable. As most of us probably know, photosynthesis (a process that happens in plants) filters carbon dioxide gases out of the air and releases oxygen. This means that cutting huge numbers of plants can have a very negative impact on the environment. It will allow green house gases to build up and contributing to global warming.

2. It further promotes the development of drought. 
Global warming brings about a lot of unfavorable consequences, including drought, which is already affecting many parts of the world. To mention, deforestation encourages higher levels of water consumption for growing livestock and crops. Instead of having a natural system of moisture recycling forests provide, water goes to food and livestock production, removing it from the natural cycle of life.

3. It focuses only on short-term gains. 
According to research, the world is already producing more than 10% of the calories it needs for the entire world population today. In fact, many countries are consuming more than 1,000 calories a day per capita, which is more than the needed amount for proper health. We should take note that, if more food is produced, then people will tend to focus more on short-term gains, instead of meeting long-term needs.

4. It is a limited resource. 
Regardless of the many monetary benefits we can get from deforestation at first, these timber profits could go away since there will not be any additional trees being planted to replace those that are harvested. Livestock and farms may not be nearly as profitable as a living, considering the thriving forests on a planetary scale.

5. It contributes to the extinction of wildlife. 
The removal of a habitat is often the foundation for the extinction of a species. When forests are cut down, it is not only the trees that are being lost, but also countless amounts of wildlife, such as mammals, birds, insects, amphibians and many other animals that make them their home. With nowhere else for them to go, they will be forced into areas that are not suited for them. In fact, there has been a drastic decline in the amount of wildlife in certain areas that have experienced severe effects of deforestation. In essence, we are removing a piece of ourselves when we no longer allow for animals to exist as they always have.

Photosynthesis is the main method by which primary production takes place in an ecosystem. What abiotic factor is a beneficial by-product of primary production?

Answers

The significant abiotic by-product of photosynthesis is oxygen. The main product of the process is glucose, which the plant uses as food. The general equation for photosynthesis is:

6CO2 (carbon dioxide) + 6H2O (water) = C6H12O6 (glucose) + 6O2 (oxygen)

It can be seen that plants are important to sustain life because they reduce the earth's carbon dioxide, and replace it with oxygen.

The answer is A: Oxygen

Two siblings live in a two-story house with a heating and cooling unit for each floor. The two have decided to conduct an experiment to determine the need to turn both units on throughout the daytime during the winter to stay warm. They decided to use both units for two weeks and recorded their observations. The following two weeks, they only used the downstairs unit and recorded their observations.Every day they charted whether upstairs and downstairs were either too cold, cold, warm, too warm, or hot. They tallied their results, learning that the two weeks of using both units; the house was a bit too warm. The month where only the downstairs unit was used, they noted downstairs and upstairs were warm. This did not support their prediction that it would be cold.They began to wonder how upstairs could still be warm during the daytime when only using the downstairs unit. What is the best possible explanation for upstairs being warm throughout the winter month when they only turned on the downstairs unit?
