CHAPTER 47 and CHAPTER 48 – Ecology. CHAPTER 6 – to describe the roles of photosynthesis and cellular respiration. ECOLOGY VOCABULARY. Carrying capacity. Cellular respiration. trophic. levels. Energy and Ecosystems . Learning Objectives. All students should be able to calculate:. The percentage of energy transferred from one . trophic. level to the next.. Percentage efficiency of energy transfers .. 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. Detritivore. an organism that . feeds off of dead plant or animal matter; breaks down organic material; . Organisms . that produce their . own. . energy. PRODUCERS. CONSUMERS. AUTOTROPHS. Organisms obtain energy from . How do populations interact?. Populations compete amongst themselves & . between . other populations. …amongst themselves. Populations compete amongst themselves & between other populations. . Community Ecology. Community. = group of populations of different species living close enough to interact. Interspecific interactions. Can be positive (+), negative (-) or neutral (0). Includes:. TROPHIC LEVELS. An organisms trophic (feeding) level is determined by the organism’s source of energy. There are 3 main trophic levels in a food web.. Autotrophs. Heterotrophs. Saprotrophs. 1. AUTOTROPHS:. Autotroph:. Heterotroph:. Food Chain:. Food Web:. Trophic Level:. Energy is transferred in ecosystems. Producers give E to . Consumers. Food chains show flow of energy (arrows  show where energy is going). In no particular order:.

What was the trophic state of Utah Lake prior to European settlement and how has it changed as development proceeded?. 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.
