Superfund sites in the U.S.

Define what a superfund site is. 2. Identify a superfund site in Florida. (A superfund site is NOT a website-it’s an actual location with high levels of pollution) 3. Give some background information on the site and the proposed plans to deal with this site. 4. Be sure to answer the following questions: Where is the problem? What is the contamination?

Examine ecology in terms of population growth and human activities on the environment

Explain the dynamics of population growth on the environment. Explain the concept of regulation of population growth through community interactions. Evaluate the effects of human activities on ecosystem and the biosphere.

Exploring plants and leaf orientation

Why have so many plants developed broad, flattened leaves? What is heliotropism, and how does it make plants more efficient? What are sleep movements? Describe the model for leaf orientation in the upper, middle, and lower levels of a leaf canopy

Color of leaf and chlorophyll degradation

Plants absorb light energy using special molecules called photosynthetic pigments (predominantly chlorophylls). These pigments absorb most of the visible light except for wavelengths in the green part of the spectrum. Consequently, plants appear green. But what happens in the fall when leaves change colors? Why are there so many different colors? And why are the colors more intense some years?
