dominant culture and a counterculture takes place it creates an uneasy symbiosis between these two interdependent cultures. There were two books selected for this research‚ one was by Ed Cray and the other was by J.P Wright on General Motors. The three core values for dominant culture in GM were “respecting authority”‚ “fitting in” and “being loyal”. J.P Wright talks about how DeLorean’s division in GM has created an uneasy symbiosis relationship between the dominant culture and counterculture. DeLorean’s

Competition: 2 or more species wanting to use the same habitat and competing for resources necessary for life * Predation: an organism (predator) captures and feeds on another organism (prey) * Symbiosis: any relationship in which 2 species live closely together. There are 3 main kinds of symbiosis: 1. Mutualism 2. Commensalism 3. Parasitism Mutualism: a situation when both organisms benefit from a relationship Examples: a bee and a flower; a sea anemone and a clown fish

Interactions between biotic components 3 types of symbiosis i) commensalism - epizoics and epiphytes ii) parasitism iii) mutualism Commensalism - interaction between one organism (commensal) benefits and the other (host) neither benefits nor harmed Epizoics - animals which live as commensals on the outside of other animals Epiphytes - plants which grow on the surface of other plants to obtain sunlight and air (do not absorb food) A shark and remora fish. The remora fish attaches itself

Section I.1 Tolerance (a) Tolerance: the ability to survive and reproduce under a range of environmental circumstances (b) Habitat: the general place where an organism lives Section I.2 Defining the Niche (a) Niche: describes not only what an organisms does‚ but also how it interacts with biotic and abiotic factors in the environment (b) A niche is the range of physical and biological conditions in which a specie

INTRODUCTION Legume plants receive nitrogen from Rhizobium which makes them possible to grow in nitrogen poor soil. In return‚ legume plants supply Rhizobium with carbohydrate‚ which is energy. This process is called nitrogen fixation‚ also known as the symbiosis of legume and Rizobium. However‚ it would be inefficient for plants in nitrogen rich soil to transfer their energy to Rhizobium in exchange of nitrogen when sufficient amount of nitrogen is present. In this situation‚ plants will not transfer its

Causes and Solutions to our Ecological Crisis The ecological crisis is a long term threat to the earth’s well being. Throughout traditional western views there is a pattern of exploitation that cannot be ignored‚ because it has put the earth and its inhabitants in a precarious position. The west has completely removed any sacred meaning from nature; there is no longer any relationship between humans‚ spirits‚ and the natural aspects of the planet. In addition to this‚ the anthropocentric view that

The interaction between biological systems creates complexity because of the vast interactions in species. There are predator prey relationships that rely on a balance between the two. If there is too many of one and not enough of another there is an imbalance that throws off the food chain. The imbalance of the food chain affects all the organisms in that community. There are many communities where humans are the cause in the imbalance and the food chain flips. Primary consumers over power tertiary

31. Molds and mushrooms are similar in the process of reproduction. They both reproduce asexually through the process of sporulation. Why these organisms reproduced anywhere? a. because the spores are lighted directly by the sun. b. because the spores are transported by air and wind. c. because the spores are very small and heavy. d. because the spores are grafted to another plant. 32. In flowering plants‚ there are two events that lead to reproduction. What are these two events? a. Fertilization
