A large hurricane destroys a coastal forest, leaving only a bare, muddy seashore.  The following year, ecologists find small sea grasses growing in the area.  What will an ecologist EXPECT to observe in later years?   This ecosystem will be converted into a grassy beach.   Eventually small shrubs will begin to grow, and after a number of years, trees will grow in this area again.   Nothing will happen because the hurricane destroyed the ecosystem.

In a lake, a typical food chain might go something like this: algae eaten by arthropods eaten by minnows eaten by pike eaten by a heron. If a toxic material were released into the pond water, which organism in this food chain do you think would be most affected by biological magnification and why?

Deforestation has contributed to erosion and dramatic flooding, particularly in parts of Asia. is this statement true or false

More Text AnoVU combined with rising sea levels increased the presence of salt water in freshwater areas. Most bald cypress seedlings cannot survive in water with high concentrations of salt. Bald cypress trees depend on occasional forest fires to prevent other types of trees and shrubs from invading their habitat. Without these fires, other tree species would eventually take over a stand of bald cypress trees and change the ecosystem. Cypress swamps benefit people and animals; they absorb water during floods, filter waste from runoff by trapping it in plants and sediments, and provide habitats and food for many species. The diagram shows food web relationships between some of the organisms in a cypress swamp.
