Extra Credit Assignment Energy Transfer in living systems Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cannot be utilized directly by all living organisms. This ability rests only with the green plants. All the other organisms have to meet their energy requirement only through the green plants. Energy that flows in the living

ecosystems. Heterotrophs are organisms that cannot make their own food‚ and gets its nutrients and energy requirements by feeding on other organisms; it’s also known as a consumer. Also an autotroph is an organism that captures energy from sunlight or inorganic substances to produce its own food; it’s also known as a producer. And every few days we checked them for changes‚ then recorded it in our eco-logs for a little over 3 weeks. When we collected our autotrophs and heterotrophs‚ we gained one

represent species that are more distantly related Chapter 2: Microorganisms • Compare autotrophs and heterotrophs. ∙ Autotrophs: use their energy source (light/inorganic compounds) to obtain their Carbon from CO2 - Photo-autotroph: use their energy source (light) to obtain carbon from CO2 - Chemo-autotroph: use their energy source (inorganic chemicals) to obtain carbon from CO2 ∙ Heterotrophs: tend to get their carbon from other organic compounds because they feed off of other organisms
Premium Evolution Genetics Plant
Protists Protists are a very large‚ diverse group of organisms‚ including the plant-like protists (algae)‚ fungi-like protists‚ and the animal-like protists (protozoans). They are all eukaryotic‚ and most are unicellular. Traditional taxonomy of protists (Kingdom Protista) did not accurately represent evolutionary relationships‚ so the classification of this group is unsettled. Modern taxonomy has rearranged the group formerly known as Kingdom Protista‚ separating the different types of organisms

called trophic levels: 1) the autotrophs‚ and 2) the heterotrophs. To maintaintheir bodies‚ grow‚ develop‚ and to reproduce‚ autotrophs produce organic matter from inorganicsubstances‚ including both minerals and gases such as carbon dioxide. These chemical reactionsrequire energy‚ which mainly comes from the sun and largely by photosynthesis‚ although a very small amount comes from hydrothermal vents and hot springs. A gradient exists between trophic levels running from complete autotrophs that obtain their
