PPT-Ecosystems: Food Chains and Webs

Standard 524 Brooke Ard 5 th Grade MathScience Griggs Road Elementary Organisms All organisms need energy to live and grow Energy is gained from food Roles that organisms serve in ecosystems are based on how they get their energy . carnivores. A carnivore is an animal that gets food from . killing . carnivores have to hunt down and kill other animals they require a large amount of calories. This means that they have to eat many other animals over the course of the year. The bigger the carnivore, the more it has to eat. You should make sure that you have many more herbivores and omnivores than . 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.. AND. FOOD WEBS. Interactions are the relationships that organisms have within an ecosystem. These relationships are usually defined by the organism’s niche..  . These interactions form food chains and food webs.. 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. . IB Diploma Biology. Ste. phen Taylor. Photo: .

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. 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. Ecosystems are made up of living and non-living things. An . ecosystem. is a place where interactions between living and non living things occur. All of this occurs within the biosphere, which is comprised of all ecosystems making the living part of the Earth. So, there are many different ecosystems on the Earth and we study them by looking at the aspects within the ecosystems. . Module 5.2. Can you see a food chain in this habitat . Food Chains. caterpillar. leaf. bird. fox. What does this food chain show?. A . leaf is eaten by a caterpillar, which is then eaten by a bird, which is then eaten by a fox. 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.. Objectives. Define and give examples of organisms at different trophic . levels. Describe how energy flows in a food chain. .. Explain why producers must outnumber consumers in a balanced ecosystem.. Thursday September 20, 2018. Agenda: Vocabulary . Quizzizz. —TODAY. DCA TOMORROW. . Learning Target: . I will identify any areas that I need to study for the DCA on Matter and Energy in an Ecosystem. (Photosynthesis, Food Chains, Food Webs, and Energy Pyramids).
