PPT-Monday TEK 12C: Analyze the flow of matter and energy through trophic levels

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. Assessment Statements. Define species, habitat, population, community, ecosystem, and ecology. Distinguish between . autotroph. and . heterotroph. Ditinguish. between consumer, . detritivores. and . 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. 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. 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). Relative importance of . allochthonous. versus autochthonous sources of. nutrients. sediments. o. rganic matter (dissolved and particulate). Productivity within a Watershed. Wetland very productive. The scientific study of interactions between organisms and their environments, focusing on energy transfer. It is a science of relationships.. The environment is made up of two factors:. Biotic factors- all . LEVELS. ECOLOGICAL. PYRAMIDS.

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.
