Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

Exam Review – January 2013 Diversity Unit - List taxonomic ranks in order. What is the significance of this order? Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ Species. Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems.
