ECOSYSTEM

Ecosystem is an ecological system formed by the reciprocal relationship between living things with their environment. Ecosystems can be said also of order unity as a whole and complete between all elements of the environment affect each other.

The study of ecosystems is ecology. Ecology comes from two Greek words, namely Oikos and logos. Oikos means house or place to live, and logos meaning science. The term ecology was first proposed by Ernst Haeckel (1834 to 1914).

Ecology is a branch of science that is still relatively new, emerging in the 70s. However, ecologists have a considerable influence on the branch of biology. Ecology study how living things can defend life by coming into contact with antarmakhluk life and things do not live in a life or the environment.

Ecologists study the following:

1. Transfer of energy and material from one living thing to another living creature into the environment and the factors that cause it.

2. Changes in population or species at different times of the factors that cause

3. Interspecies relationship occurred (interaction between species) of living things and the relationship between living things with their environment.

Forming components of the ecosystem are:

Components living (biotic).

Nonliving components (abiotic).

Both these components are in one place and interact to form an organized unity. For example, in an aquarium ecosystem, ecosystem consists of fish, water plants, plankton will float on water as a biotic component, while including abiotic components are water, sand, rocks, minerals and oxygen dissolved in water.
