WebAug 9, 2015 · Genetic engineering is a term used to describe biotechnological methods used by scientists to directly manipulate an organism’s genome. Under this definition GMOs do not include plants or animals made by selective breeding, or animals modified by being given hormone supplements or antibiotics. WebPlants, algae, and microscopic organisms such as phytoplankton and some bacteria, make energy-rich molecules (in other words, their food) from sunlight, water, and carbon dioxide during the process called photosynthesis (“photo” means “light, and “synthesis” means “to make” – photosynthesizers are using sunlight to make food).

WebMost scientists generally agree that a species is a group of organisms that share an evolutionary and ecological history and that are distinct from other groups. The primary difference in the species concepts described above is the forms of evidence used to quantify those differences and to categorize individuals as members of a particular species. Webthem. It looks at an organism’s cell type, its habitat, the way it gets food and energy, the structure and function of its features, and the common ancestry of organisms. Systematics also uses molecular analysis—the study of molecules, such as DNA, within organisms.
