ECOLOGY: PRINCIPLES OF ECOLOGY INCLUDES: Ecology of abiotic factors, individual organisms, populations, interaction among species, communities, ecosystems, biomes and biosphere. – the study of the all the inter-relationships between living organisms and their surroundings. LEVELS OF ORGANIZATION: - Organisms - Populations - Communities - Ecosystem - Biome - Biosphere CHARACTERISTICS OF A POPULATION – * Population size = number of individuals making up its gene pool *
Significance of Ecology Studying ecology is very important, because a simple change in the environment can have a profound effect on all living things; the destruction of one species can mean the death of many others. We cannot continue to harm our environment due to a poor understanding of ecology. So the more we know the better. For example, humans continue to destroy wildlife habitats in order to build cities; we introduce contaminants such as pesticides and industrial wastes into the environment;
1590 – Zaccharias and Hans Janssen; Two Dutch eye glass makers, were the first to experiment with multiple lenses. They found that the objects observed under these lenses appeared greatly enlarged, creating both the forerunner of the compound microscope and the telescope. 1674 – Anton van Leeuwenhoek was the first to build a simple microscope with a single lens for the examination of blood, yeast, insects, and many other tiny objects. He was also the first person to describe microorganisms and
ECOLOGY In the world that we live in, we have a lot of ecologies that affect us in everyday life. This paper will discuss the local ecology of the Baltimore, Maryland region. It will further discuss the distinguishing factors of this local ecology and environment. It will show how human activates and how global warming might affect the ecosystem. Finally, it will show how relative to other parts of the world, will Maryland’s local ecosystems are affected more or less. What is ecology? Ecology
Describe your local and surrounding ecologies and environments III. List the specific factors that distinguish your local ecology and environment. IV. Discuss how human activities have affected your local ecosystems V. Describe the ways that global warming might affect your local ecosystems VI. Relative to other parts of the world, would your local ecosystems be affected more or less? VII. Conclusion Introduction Ecology is known as a scientific discipline
Ecology (from Greek: οἶ κος, "house"; -λογία, "study of") (ecos logos the study of the home). It is the study of relationships among living organisms (plants, animals) and their physical environment (home). The prehistoric man was not a scientist but was able to realize through observation these relationships because he had to deal with everything surrounding him. He noticed repetitions (year, seasons...); he had to understand certain phenomena to know when to plant, when to breed, where to go (Bedouin

Ecology and Environmental science is a part of business studies Ecological environment refers to all living and non living thing around us within which we live and work. People have a two way relationship with the ecological environment. An individual lives and work is affected by the ecological environment he or she lives in. At the same time ecological environment gets affected by the people in it. Relevance of ecological environment on the business is very similar to it relevance
Ecology Unit Ecology: the study of how living and non-living things interact with their surroundings Fundamental Concept: All living things are interdependent and they interact with each other and the environment Interactions result in a flow of energy and material cycling Environment = every living and non-living thing that surrounds an organism Biosphere = all locations in, on, and above earth where life exists; biologically inhabited part of the planet
Cultural and Diversity Native American and Hydroelectric Dam Denise Berger Chamberlain College of Nursing Native American Culture and Hydroelectric Dam A large hydroelectric dam built in the 1950s and 60s created a 1 million acre impoundment, and it has been a major means of both producing electricity and flood control for many decades. In early spring each year, the water level above the dam is lowered to allow a reservoir for upstream snow melt and runoff later released downstream in a controlled
