among the Different Components of the Ecosystem I. Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population‚ community‚ and ecosystem ecology although it also includes a wide variety of fields. Both the living (biotic) and the

1a. What are the two goals of systematics? The goal of systematics is to organize living things into groups that have biological meaning. (Taxa or Taxon) 1b. Why do common names of organisms – like daisy or mountain lion – often cause problems for scientists? The common names of organism often cause problems for scientist because common names can change meaning among languages and from place to place. 1c. The scientific name of the sugar maple is Acer saccharum. What does each

are living organisms whose cells are larger and more complex than prokaryotic cells and contain complex structures enclosed within membranes. Scientists believe that eukaryotes have evolved from prokaryotic symbiotic communities. If we use the rules of nomenclature and look at the binomial “eukaryote”‚ eu means good or with and karyon means nucleus; therefore‚ a simplified definition of eukaryotes is “with a nucleus”. a. Algae - Algae are a large and diverse group of simple organisms that can be

of life”(Louis Schwartzberg). Across the Earth‚ the main reason why cell division is so that organism can make more copies of the cells. Reproduction is the process of making offspring that are able to survive in the environment they are born into. There are two major forms of reproduction‚ which are asexual reproduction and sexual reproduction. Sexual reproduction is the production of new living organism by combining genetic information from two individuals of different sexes (an egg and sperm cell)

Plant tissue culture is a widely used procedure in plant biology in which organism is planted from the explants of the living plants in a nutrient medium under aseptic conditions. There are both advantages and disadvantages of plant tissue culture. Advantages: 1. To produce many copies of the same plants then which may be used to produce plants with better flowers‚ odors‚ fruits or any other properties of the plants that are beneficial to the human beings. 2. To produce plants anytime we want

Interaction between Abiotic and Biotic Components All living organisms depend upon their environment for survival essentials: 1) food 2) shelter 3) breeding site. In turn the organism interacts with the environment in several ways. For example a plant uses the environment for the three purposes named above but in turn it also removes carbon dioxide and water from the air‚ it gets eaten by an animal or a parasite and it depends on the soil for its support. Therefore the plant is interacting
