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 . Value Chains. 1. Mainstream . food supply chains have these characteristics:. 2. Each company in the chain seeks to buy as cheaply and sell as expensively as . possible.. This leads to: . business relationships that are competitive and adversarial (win-lose). 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.. 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.. 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. Sheet Web. Picture by Rod Crawford. Sheet webs do not look planned. Small ones are often called “cobwebs”.. Cobweb. Photo by Jim Stratton. Funnel Web. Picture by Rod Crawford. Almost like a nest, it is deep.. 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. 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.. Aquatic ecosystems are primarily determined by the ecosystem’s . salinity. . Salinity refers to the dissolved salt content of the water.. Aquatic ecosystems are divided into freshwater and marine ecosystems.. What are Ecosystems? . Groups of living things and the non-living environment in which they live.. The people that study ecosystems are called: . “ecologists.”. Let’s look at the living parts of the ecosystem:. The . altiplano. is a high plateau in the Andean regions of two South American nations.. The . varzea. , or “flooded forest,” is found mainly along the Amazon River in this nation.. The . cerrado.
