Zoologists, also known as animal biologists or animal scientists, study animals in their natural habitats and in laboratory settings to understand their behavior and aspects of their life. Many institutions offer bachelor's, master's and doctoral programs in zoology. At the undergraduate level, students complete general education classes, like composition and psychology, and get the basics of animal science and biology. This degree option usually takes 4 years to finish.
Living things need nutrients because nutrients provide us with the energy we need in order to live, they also provide our bodies with the raw materials for constructing the m â¦ olecules on which our body survival depend. 2 people found this useful.
To survive and reproduce, organisms need a supply of raw materials (water, nutrients) and a source of energy (light, heat, or chemical energy). Carbon-based organisms are composed of carbon and hydrogen chains so they need more carbon and hydrogen, and oxygen to form or use carbohydrates.   The energy that all microbes need to survive comes in the form of glucose (sugar). This can come from many sources such as being a parasite and sucking from other â¦ microbes, and eating plants or animals.     Answer By Awesomeluke53  . 1 person found this useful.
