Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

All living things must maintain homeostasis in order to stay alive. A) Homeostasis: A balanced state in an organism’s body. B) Failure to maintain homeostasis results in disease or death. C) Homeostasis is often maintained using feedback mechanisms. 1. Feedback mechanisms

Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic

Producers are able to harness the energy of the sun to make food. The process is called photosynthesis. * Consumers Consume means “eat” Animals are consumer because they eat (consume) food provided by plants and other animals. They also called Heterotrophs because animals cannot make their own food so they must eat plants and/or other animals. In short

Producers are organisms that are able to create their own food through photosynthesis. They are autotrophs (green plants) that are located in the lowest part of the energy pyramid‚ and provide the source of energy for all the other organisms. 3. What type of organisms are decomposers? Decomposers are organisms that break down dead animals‚ plants
