Chapter 3 Ecosystems: What Are They and How Do They Work? Section 3-1: What Keeps Us and Other Organisms Alive? Earth’s life support system has four major components: The atmosphere (air) The hydrosphere (water) The geosphere (rock‚ soil‚ and sediment) The biosphere (living things) The Atmosphere The atmosphere can be divided into two layers: The troposphere extends about 17 km above sea level at the tropics and about 7 km above the north and south poles. It contains the air we breathe: 78% Nitrogen

ABSTRACT An ecosystem is a very important part of our natural world. Everything relates to nature in one way or another. In turn‚ should be treated with respect and should be not tampered from its original state. With animal annihilation and extinction aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population

Marine ecology is a subset of the study of marine biology and includes observations at the biochemical‚ cellular‚ individual‚ and community levels as well as the study of marine ecosystems and the biosphere. The study of marine ecology also includes the influence of geology‚ geography‚ meteorology‚ pedology‚ chemistry‚ and physics on marine environments. The impact of human activity such as medical research‚ development‚ agriculture

Trawling vessels have progressed to now contain a large capacity of fish and have several plants to package fish into tins‚ reducing the time the vessels have to return to shore and maximise the time spent in the ocean collecting more fish. Fishing industries are reducing fish reproduction by capturing and killing fish who have not yet matured or reproduced‚ are not the proper weight‚ have no market value or are illegal to catch. This quickens the amount of fish

In nature‚ organisms of all shapes and sizes greatly affect the ecosystems which surround them. As African elephants stomp through the savannah‚ pushing over trees and crushing shrubs‚ the forest is kept from overtaking their grasslands. The predatory nature of wolves in the Pacific Northwest prevents overpopulation as they hunt out rabbits and deer. While ecosystems rely on animals to maintain a healthy status‚ they also rely on the environment to keep from drastic change. However‚ glaciers all
