act of competing; rivalry. Supplement In biology‚ competition is one of the many symbiotic relationships occurring in nature. Same or different members of species compete for resources‚ especially for limited natural resources. Predation Definition noun A form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey. Supplement In ecology‚ predation is a mechanism

UNIT 1 DIVERSITY IN THE LIVING WORLD Chapter 1 The Living World Chapter 2 Biological Classification Chapter 3 Plant Kingdom Chapter 4 Animal Kingdom Biology is the science of life forms and living processes. The living world comprises an amazing diversity of living organisms. Early man could easily perceive the difference between inanimate matter and living organisms. Early man deified some of the inanimate matter (wind‚ sea‚ fire etc.) and some among the animals and plants. A common feature of all

For each one found the group members recorded it down tallying them all up as they went along. All the groups came together comparing and sharing data to get total numbers of each species. One group calculated the percent coverage‚ which would then be used to calculate the chi squared ((obs.-exp.) ^2/ exp

Technical University Purpose The purpose of this lab is to explain what would happen if a species were split into two groups by an earthquake‚ creating a physical barrier between the two groups. Showing how the formation of a new species can evolve. Introduction Speciation is when a species is created from the splitting of a species. In other words if a group of a certain species is separated say by an earthquake‚ the group that remains in the geographical area will stay the same‚ but

Introduction Evolutionary tree also known as phylogenetic tree is describing a system of clustering and classification of related organism that aims to show their evolutionary history. It is a diagram depicting the evolutionary relationships between species or groups of organisms as usually dichotomously branching lines to form a treelike pattern. In some trees‚ changes in the relative abundance of a lineage are indicated by the width of the branch.(Oxford‚ dictionary) In this experiment we will use

Darwin spent five years exploring the world. Darwin traveled to many places mainly in the Southern Hemisphere. As he traveled from place to place‚ Darwin was surprised‚ by the similarities between the species. He wrote in his journal of the Galapagos Islands‚ "...there is even a difference between the inhabitants of the different islands; yet all show a marked relationship with those of America‚ though separated from that continent by an open space of ocean‚ between 500 and 600 miles in width."

is still used today. He gave every plant only two names‚ the first for its genus and the second for its species. Aster‚ for instance‚ is the genus of a group of plants that have many characteristics in common and are closely related. But with more than 250 different asters in this genus‚ the only way you can tell one from the other is to know what species it is. The specific epithet‚ or species name‚ further describes the plant by its characteristics or by who discovered it or where it grows. Linnaeus
