Taxonomy is man’s attempt to understand the organizational structure of living organisms. It originates from the idea that there was a supreme being who created everything and‚ therefore‚ a perfect organization to living organisms must exist. Each with their own opinion on how organisms should be classified‚ philosophers and scientists alike have attempted to make the perfect arrangement of organisms. These methods are all derived from previous methods‚ hence we must look at Aristotle and Linnaeus

Invasive Species have been described as an organism which is not native‚ and causes negative effects on the ecosystem‚ and to the health of humans. These organisms can be Fauna‚ Flora (Flora and Fauna refer to plant and wildlife‚ respectively)‚ a fungus or a bacterium. However‚ not all introduced species are invasive‚ but invasive Fauna and Flora‚ have been said to be the 2nd greatest threat to biodiversity post habitat loss. In his book‚ Invasive Species in a Changing World‚ Richard J. Hobbs (2013)

The cell is the basic functioning unit of organisms in which chemical reactions take place. These reactions involve an energy release needed to support life and build structures. The cell consists of membrane bound organelles‚ which are responsible for the division of labour. There are two main classes of cells- Prokaryotes which are cells without a nucleus‚ where the DNA is spread around the cytoplasm of the cell‚ an example of a prokaryote is a bacterium (See Figure 1). The other class is the Eukaryotes

will be discussed further in the chapter on chemistry. Cells are considered to be the smallest structure that is alive. They are often too small to see without the aid of a microscope. All living organisms are composed of cells. The smallest organisms are composed of a single cell; larger organisms are composed of more than one cell. Similar kinds of cells may be arranged together to form a tissue. Tissues have specific properties and functions. For example muscle tissue is composed of muscle

autotrophic and heterotrophic. Autotrophic organisms make their own food by the process of photosynthesis e.g. plants. Heterotrophic organisms cannot make their own food (i.e. cannot carry out photosynthesis)‚ therefore must eat other organisms to get their nutrients e.g. animals. A food chain is the feeding relationship among organisms or the series of living organisms that eat each other. A food chain shows the transfer of energy from one organism to another. In drawing a food chain‚ we use

Explain why the process of mitosis and meiosis are both important to a living organism. When would an organism need to undergo the process of mitosis? Meiosis? What would happen if meiosis did not occur? Mitosis is the cell process of growth and division whereas meiosis is the process of developing reproductive cells. The sperm and egg are critical components for almost all living organisms. Every living organism begins with one cell that came from our father’s sperm fertilizing our mother’s

high in the forests. 3.1.3. Explain why removing the capuchin monkeys from the rainforest ecosystem would have a negative impact to other living organisms like squirrel monkeys‚ insects‚ raptors and palm plants. The capuchin monkeys have an important role in the rainforest ecosystem and removing them would make a negative impact to other living organisms that benefit from them. Just like the squirrel monkeys‚ they depend on the capuchin monkeys for food for they get the leftovers of the capuchin

Photosynthesis-the process by which an organism uses the energy from the sun to produce its own food c. Autotrophs- organisms that are able to produce their own food d. Heterotrophs- organisms that cannot make their own food and must obtain it from other organisms e. respiration -- the process by which food is converted into usable

ecosystem which at various locations‚ contain all living organisms and nonliving matter in one place. Within the ecosystem are many organisms sharing the elements is called a community. For instance‚ a forest community would contain animals‚ plants‚ and insects all of which are affected by the nonliving matter that surrounds them. The last of the first four systems is called a population. A population is a group of one type of organism‚ group‚ or individuals who interact with each other. The
