People must learn to live in harmony with their ecosystem. Forests have been of great importance to mankind since prehistoric days. 60% of the earth was once covered with forests. With the development of civilization‚ large areas have been cleared to make way for farms‚ mines‚ towns and roads. Today about

Ecology is the science of the study of ecosystems. Ecological balance has been defined by various online dictionaries as "a state of dynamic equilibrium within a community of organisms in which genetic‚ species and ecosystem diversity remain relatively stable‚ subject to gradual changes through natural succession." and "A stable balance in the numbers of each species in an ecosystem." The most important point being that the natural balance in an ecosystem is maintained. This balance may be disturbed

The Importance of The Florida Everglades The Florida Everglades is a wetland ecosystem located in Southern Florida. It is home to a numerous amount of plants and animals. The Everglades faces many problems‚ such as invasive species and pollution. Not only do the plants and animals that live there benefit from the Everglades‚ but humans do too. It is important that the Florida Everglades remains a healthy ecosystem. The Florida Everglades has biodiversity‚ it benefits humans‚ and it houses many endangered

hard-shelled organisms that loggerheads consume are either discarded or ingested and later deposited with feces at a different location. By reducing the particle size of the shells‚ loggerhead turtles contribute to nutrient recycling in benthic ecosystems by increasing the rate of shell disintegration. Additionally‚ a foraging behavior called infaunal mining has a significant effect on substrate characteristics (Bjorndal 2003). One method loggerheads use to find prey is clearing away sand to expose

The result of the research showed the physical and biological components of the quadrat area and what were the negative impact drawn by human activity on the ecosystem. During the investigation‚ ruler and camera were used to collect data and pictures. Also‚ three tables‚ a food chain‚ and a food web were drawn to clearly illustrate the findings. In the third part‚ the classifications of the five species found in

1.2 How have environmental cycles changed? The capacity of ecosystems to provide benefits to humans‚ that is to provide ecosystem services‚ derives from environmental cycles of water‚ nitrogen‚ carbon‚ and phosphorus. These processes have in some cases been significantly modified by human activity. Changes have been more rapid in the second half of the 20th century than at any other time in recorded human history. Water cycle: Water withdrawals from rivers and lakes for irrigation‚ urban uses‚

to satisfy my requirement for a Natural Science class‚ however‚ this class has intrigued me and is more interesting than I expected. I have learned a lot about the environment‚ and I really enjoyed learning about ecosystems and the interaction between the biotic and abiotic of ecosystems. I found the earth’s major biomes particularly interesting‚ and would like to reflect on them. According to the text book‚ a biome is a large‚ relatively distinct terrestrial region with similar climate‚ soil‚ plants
