Trophic Cascades. Herbivores can limit plant populations, but…. In most places, plants are abundant and herbivores don’t limit plant growth. So…why is the world green?. HSS hypothesis. Assessment Statements. Define species, habitat, population, community, ecosystem, and ecology. Distinguish between . autotroph. and . heterotroph. Ditinguish. between consumer, . detritivores. and . Conceptual Questions. Elementary Grade 7: Life Sciences. Created by Kshamta Hunter . EDCP 349 Section 401 Winter 2011. In this lesson. Ecosystem Vocab. Parts of the ecosystem. Abiotic/Biotic parts of the ecosystem. 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 .. 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 . Relate the structure of each of the major plant organs and tissues to physiological processes.. Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.. 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). Food Web. Energy . Paramid. Period 6. Fowlers, Jonah. Hendricks, Justina. Dennis, . Tamesha. Abreu, Anabel. McNeal, . Kahil.

Photosynthetic organisms, such as plants and algae, change light energy from the sun into energy that they can use to grow. . PRESS SLIDE SHOW. Objectives. Realise . in every food chain there is a producer and consumers (4b). Draw food chains from list of animals given(4b. ). Describe the feeding relationships shown by food chain (.
