Basic Ecology Terms: Ecology- the study of how organisms interact with their environment Organism- a living thing that gets food‚ water‚ shelter‚ and other things it needs to live‚ grow‚ and reproduce from its environment Habitat- environment that provides needed things Biotic Factors- the living part of a habitat Abiotic Factors- the non-living part of a habitat (soil‚ oxygen‚ water‚ sunlight‚ temperature) Species- a group of organisms that can mate with each other and produce offspring that

Homeostasis is a mechanism that allows organisms to maintain stable internal conditions (Reece 2014). The capability to perform homeostasis is essential for the survival of all organisms. Homeostatic mechanisms include a range of responses that regulate internal imbalances‚ including body temperature. A vital component of homeostasis is known as thermoregulation‚ the process of maintaining temperatures within a normal range (Reece 2014). When ambient temperatures change‚ animals must control their

biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual. In asexual reproduction‚ an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By

How can we tell if an organism is alive or not? Is a virus ‚ prion‚ virod‚ or a rock a living organism? What is life? Biologist have studied what makes organism alive for many years and have come to the conclusion the there are nine characteristics of life. Each characteristic has a property which applies to how and organism is alive. Life characteristics are as follows: order‚ metabolism‚ motility‚ responsiveness‚ reproduction‚ development‚ heredity‚ evolution‚ and adaptation. All of the characteristics

wonderful. It contains wide range of life forms. 1.1 What is living – Living organisms are self-replicating‚ evolving and self-regulating interactive systems capable of responding to external stimuli. Living organisms exhibit following distinctive characteristics. All Living Organisms grow: Twin characters of growth are increase in (a) mass and (b) number of individuals. Cell division leads to growth of an organism. External Growth is shown in non-living bodies where the accumulation of

Life on Earth. 1. Analysis of the oldest sedimentary rocks provides evidence for the origin of life. * Identify the relationship between the conditions on early Earth and the origin of organic molecules. * Scientists estimate that the universe is 10-20 billion years old and arose as a big bang‚ which is still expanding the universe. * The early Earth was very different from the Earth today and no oxygen was present. This means that there was no ozone layer exposing the Earth’s surface
