PPT-Energy Flow Pyramids and Trophic Levels

TROPHIC LEVELS An organisms trophic feeding level is determined by the organisms source of energy There are 3 main trophic levels in a food web Autotrophs Heterotrophs Saprotrophs 1 AUTOTROPHS. Assessment Statements. Define species, habitat, population, community, ecosystem, and ecology. Distinguish between . autotroph. and . heterotroph. Ditinguish. between consumer, . detritivores. and . Chapter 13, Section 13.4. This is called an energy pyramid. It shows how energy is lost moving from the producers to each subsequent, higher, trophic level.. Objectives. To describe the structure of a food chain.. 7-4.2. Food Chains. Use pictures or words and arrows to show the movement of energy through the trophic levels of organisms. . The . trophic level . of an organism . indicates the position. that the organism occupies in the food chain—what it eats and what eats it. . Chapter 13, Section 13.4. This is called an energy pyramid. It shows how energy is lost moving from the producers to each subsequent, higher, trophic level.. Objectives. To describe the structure of a food chain.. Energy Transfer. Energy transfers from one organism to another when they are consumed and metabolized.. Energy can be followed based on how organism obtain energy.. Trophic levels . – the position of an organism in a sequence of energy transfer. Energy Transfer. Energy transfers from one organism to another when they are consumed and metabolized..

Populations compete amongst themselves & between other populations. Mrs. Joelle R. King. Science Teacher. Food Chains. Food chains. use pictures or words and arrows to show the movement of energy through the trophic levels of organisms.. The . trophic level. of an organism indicates the position that the organism occupies in the food chain.. Every organism requires energy to carry out life processes such as growing, moving, and reproducing. Photosynthetic . producers. such as plants convert the light energy from sunlight to the chemical energy of organic compounds. . using various models including . food chains. , food webs, and ecological pyramids. Lesson frame. :. We will analyze the flow of energy and matter through a food chain.. I will complete the Looney Labels Food Chain activity. LEVELS. ECOLOGICAL. PYRAMIDS. The . ____. is the . ______________. for food chains.. . is a sequence of feeding relationships describing . ______. ___________________. .. source. Ecosystem. A community and its abiotic environment. The sun is the main source of energy for most ecosystems. All life that you see on Earth’s surface relies either directly or indirectly on sunlight. Ecosystem is defined as the system resulting from the integration of all living and nonliving factors of the environment.. The word ecosystem is not the synonyms of habitat, community or some other similar description terms. Rather it is a technical term in ecology and refer to a system of living and non living components interacting as a whole. .
