Environmentalist

If you are preparing for a role as Environmentalist, then you will find these interview question and answers helpful for your next job interview.

Q.1 Name some of the causes of Environmental Change.
1. Exospheric Effects: The exosphere is the first source of environmental change since the interactions between the atmosphere, biosphere, hydrosphere, pedosphere, and troposphere produce environmental cycles, trends, and steady states. 2. Cosmic Effects: The sun is the most important source of the power of the exosphere. Steady-state changes about periodic fluctuations are promoted by solar influences. A number of exospheric processes are adjusted to solar cycles. Also, some exospheric processes are attuned to various astronomical pulses, such as orbital changes in the sun and the planets and the solar system’s passage around the galaxy. 3. Geological Effects: Cycles, steady states, and trends in the exosphere are also produced by geological forces. However, the core and mantle processes act through the agency of the lithosphere. The mechanism of plate-tectonics influences sea-level change, volcanic and mountain building activities, continental drift, and true polar wander.
Q.2 What is Ecology?
Ecology refers to the study of relationships between living organisms and the environments in which they live in the science of Ecology.
Q.3 Describe the types of Ecology?
Scientists have classified ecology into: Firstly, Autecology, which involves the study of one species of organism. Secondly, Synecology, which is the study of communities or entire ecosystems. Thirdly, Habitat ecology, which is the ecological study of various habitats on earth and their effects on the organisms living there. Then, Community ecology, which is the study of the local distribution of animals in different habitats, the recognition and composition of community units, and succession. After that, Applied ecology, which is the application of ecological concepts to human needs and requirements like forest conservation, animal husbandry, agriculture, wildlife management, etc. Lastly, Systems ecology, which is a relatively modern branch of ecology, deals with the analysis and understanding of the function and structure of ecosystems.
