•Describe your local and surrounding ecologies and environments.
Ecology is the relations and interactions between organisms and their environment. (Dictionary.com 2013) An ecosystem is comprised of living organisms together with their surrounding environment. The abiotic constituents found in the local ecosystem include; water, minerals, soil and other nonliving constituents such as sunlight and climate. The living part of the ecosystem is referred to as biotic. Biotic and abiotic constituents are linked together by nutrients cycling and energy flow. (Integrated Science, 2009) Sun is the main source of energy in an ecosystem which is transferred through an ecosystem through the food chain. The main components of an ecosystem include

Forests act as carbon sinks and thus purifies the environment which plants and animals rely on. Agricultural practices are another factor which influences the local ecosystem. Human beings cut down trees in order to get space for farming. This leaves the land stripped of its plant cover and allows nutrients to be washed away. This affects the living organisms in that specific ecosystem since they depend on those organisms for their food. During cultivation, human beings use chemical fertilizers and pesticides on the land. When chemicals are washed away in to water sources, they affect the living organisms in the nearby water masses. Also application of chemicals changes the soil properties such as soil PH. This affects the organisms living in the soil. While there are a lot of negative aspects to some of the native organisms the changes made by humans have allowed cattle, corn, and other plants and animals to thrive.
Other human activities which have affected the local ecology include; waste disposal. There are various ways of that human’s dispose of waste. On way is to bury it underground. This affects the local ecology since things such as explosives and poisonous substances buried under the soil may be hazardous. Poisonous substances buried in the soil may find their way to water masses killing the local animals and organism.
