PPT-Trophic networks

Typical terrestrial food with six trophic levels and 15 functional groups Each functional group guild may contain many species Plant producers Herbivores Small predators Large predators. Ecology. ECOLOGY READING. CHAPTER 47 and CHAPTER 48 – Ecology. CHAPTER 6 – to describe the roles of photosynthesis and cellular respiration. ECOLOGY VOCABULARY. Carrying capacity. Cellular respiration. 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. 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. Unit 5 - Ecology. Introduction. Relationships exist in order for one or both organisms to get food (energy).. Sunlight is the main source of energy on Earth.. Section 1. Food Chains/Food Webs. Feeding Style. Energy into the earth. Of 100% of earth’s energy, how much comes from the sun. Of all the sun energy, how much is taken up by photosynthesis on earth? . What happens to most of . the . sun’s . energy? . 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. 1. Local Area Networks. Aloha. Slotted Aloha. CSMA (non-persistent, 1-persistent, . p-persistent). CSMA/CD. Ethernet. Token Ring. Networks: Local Area Networks. 2. Data Link. Layer. 802.3. 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.
