Anth1 Response Paper Evolutionary Arms Race Right now there is tense development going between Russia and the United States. Russia is seeking to expand into the Ukrainian Crimea region‚ setting the stage to the once known “cold war”. The film “Evolutionary Arms Race” arrays a comparable situation going on between predator and prey. Both sides are vying for dominance over one another. Through biological and cooperative factors‚ it propels species to evolve into survival fitting machine. In

Population is all the organisms that both belong to the same species and live in the same geographical area. The area that is used to define the population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border. Ecosystem which consists of all the organisms living in a particular area‚ as well as all the nonliving‚ physical

Task one A). How do living things interact? Living things find a way to live off the land. Not with artificial flavouring or stuff like that. But it may not last unless we take good care of it. Living things interact by: 1). Viruses Learn about viruses and their surroundings‚ and how they are created. What is a Virus A virus s a small‚ NONLIVING particle that invades and then reproduces inside a living cell. Viruses are considered nonliving because they are not cells. They cannot: * use energy

Symbiosis: The general term used to describe intimate association between pairs of species is symbiosis. Most ecologists further divide the term into three categories‚ i.e. mutualism‚ commensalisms and parasitism. A. Mutualism: Two organisms live together in such a way that both are benefited. This association is usually a permanent one. a. Lichen There are several thousand species of lichen. They are commonly found on exposed rocks and tree trucks. They can even be found on exposed

Eco-Industrial Parks: The Case for Private Planning Industrial ecologists are championing eco-industrial parks or EIPs as tools for pursuing sustainable development. An EIP is a community of companies located in one region that exchange and make use of each other’s by-products or energy. Among the best known is Kalundborg‚ Denmark‚ a city in which the major industries and the local government trade their waste streams and energy resources. Many commentators see Kalundborg as a model that should

Some of these characteristics may be deemed bizarre. Plants have come a long way since their shift to terrestrial habitats from aquatic habitats millions of years ago. From the development of the cuticle to prevent water loss to the evolution of vascular tissues to provide for efficient internal transportation‚ all evolutionary changes took

Species Interaction * The relationships between two species in an ecosystem. * The interactions between two species need not be through direct contact. Species may affect each other through intermediaries such as shared resources or common enemies. Major factors in evolution and adaptation: * Predation * Competition for scarce resources Terminologies: * Habitat – the actual physical location where a species lives. * Conditions – physical or chemical attributes of the

2) Predation a. One animal‚ the predator‚ is eating another animal‚ the prey. (ex. Lions eating zebras) b. Consumption of one organism by another (doesn’t have to be an animal). Herbivore – an animal eating a plant. 3) Symbiosis (“living together”) – close relationship between individuals of two species. a. Parasitism i. A relationship between two species in which one species (the parasite) lives in/on another (the host) gaining food from it. ii

photosynthesis are eaten by the smaller fish like the minnows. Then larger fish like bass‚ trout‚ and pike eat these smaller fish. Finally birds‚ large mammals‚ and humans catch the large fish. In the freshwater biome‚ there are several examples of symbiosis. The relationship between the freshwater sponge and spongillafly is an example of paratism. The spongillafly lays its eggs on the sponge‚ and then they hatch and feed off the sponge. Another parasite is the flatworm. It resides in organisms such
