What's the relationship between environmental science and environmental sustainability? What are some topics that are in the scope of Environmental Science? What are some overlaps of the Environmental Science and Geology fields? What is Environmental Engineering? What is the difference between Environmental Science and Environmental Studies?
What are some jobs in the Environmental Science field? The energy that comes to the earth comes from sun that means sun is the source of energy for the ecosystem. The feeding relationship in ecosystem is food chain and food web.
To maintain the ecosystem many biochemical cycles are going on like water, carbon, nitrogen, and phosphorus and limited nutrients. There are various studies related to ecology like bioecology i. The increase in human population demands for the development and utilize the natural resources highly present in environment. The science which deals with the study of the biota, their environment and interactions is known as Ecology.
Ecology derived from the Greek word Oikos meaning habitation, and logos meaning study, i. This is the study of ecosystem , which describe the relation between the organisms with different habitats [ 1 ]. The environment of an organism includes both biotic and abiotic factors. These two factors have to coordinate each other to share the resources that are present within the environmental ecosystem [ 2 ].
To understand about this mutual relationship we have to study ecology. Human being is also the part of ecosystem. The ecological studies are all about connections of all life forms in earth and their various types of ecology Figure 2.
Organism Ecology. This is the study of organism respond to stimuli caused by physical environment. Understanding these changes can help ecologists anticipate future ecological challenges and inform other scientists and policymakers about the challenges facing their local ecosystems. Ecology first began gaining popularity in the s, when environmental issues were rising to the forefront of public awareness.
Although scientists have been studying the natural world for centuries, ecology in the modern sense has only been around since the 19 th century. Around this time, European and American scientists began studying how plants functioned and their effects on the habitats around them. Eventually, this lead to the study of how animals interacted with plants, other animals, and shaped the ecosystems in which they lived.
Today, modern ecologists build on the data collected by their predecessors and continue to pass on information about the ecosystems around the world. The information they gather continues to affect the future of our planet. Human activity plays an important role in the health of ecosystems all around the world. Pollution emitted from fossil fuels or factories can contaminate the food supply for a species, potentially changing an entire food web.
Introducing a new species from another part of the world into an unfamiliar environment can have unintended and negative impacts on local lifeforms. These kinds of organisms are called invasive species. Invasive species can be any form of living organism that is brought by humans to a new part of the world where they have no natural predators.
The addition or subtraction of a single species from an ecosystem can create a domino effect on many others, whether that be from the spread of disease or overhunting.
