PPT-How Organisms Obtain Energy

How an organism obtains energy is an important part of a species niche The ultimate source of energy is from the sun Two ways to obtain energy AUTOTROPH HETEROTROPH Autotroph EX Plants Makes . A. Introduction – There are multiple criteria by which you can classify an organism. 1. Metabolic Activities (Carbon, Energy & Oxygen sources). A) Recall that microbes may vary in their carbon & energy sources. A. Introduction – There are multiple criteria by which you can classify an organism. 1. Metabolic Activities (Carbon, Energy & Oxygen sources). A) Recall that microbes may vary in their carbon & energy sources. What do living things need to survive?. Organisms need a source of energy to live. They use food as their energy source.. Autotrophs are organisms that make their own food.. Organisms that cannot make their own food are called heterotrophs. They feed on other organisms to obtain energy. . Standard and EQ. Standard. Essential Question. SZ5. Students will evaluate the relationships between humans and other animals. . How do organisms receive energy from other organisms?. I Will Be Able To…. and Matter Exchange in the Biosphere. Unit A. Systems. Objects . or . groups of objects . that has a relationship to something else. Open . Energy and matter cross the systems boundaries. humans, trees.                       . Ecology. – the study of the relationships between organisms and their environment. Ecosystem. -- a community of organisms and their nonliving environment. The Characteristics of Life. Life!!!. All living things share some basic properties.. Cellular Organization. Reproduction. Metabolism (Obtain and Use Energy). Homeostasis. Heredity. Responsiveness. Growth and Development. Biosphere: All life on earth and parts of earth in which life exists (land, water and atmosphere). Studying Our Living planet. Science of Ecology. Study of interactions of living things, their surroundings or environments. 2.. . Glucose. is main source of food for cells. 3. Cells break chemical bonds of glucose; energy . released. Slide # 2. Go to Section:. Cells Need Energy. Respiration. Cellular Respiration. If cellular respiration took place in just one step:. Lack a nucleus. DNA is naked, a single loop not bound in a chromosome. May contain plasmids (small circular fragments of DNA). Have ribosomes, but no other organelles.. DNA present as a long circular molecule.. 3.1.2 Micro-organisms. 3.1.3 Monera, e.g. Bacteria. Follow-Me – . iQuiz. Q. To which kingdom do bacteria belong?. Antibiotics. Capsule or Mucilage; Protection. Disease-causing. Decompose dead organisms; Recycle nutrients. Ecology .

Ecologists . study the flow of energy through communities to discover nutritional relationships between organisms. and modes of nutrition in . bacteria. Nutrition is substances used in biosynthesis and energy production and therefore are required for all living things.. Bacteria, like all living cells, require energy and nutrients to build proteins and structural membranes and drive biochemical processes.. Assitant. professor. Dr. D. Y. . Patil. ACSW College .
