2. What are Autotrophic and Heterotrophic nutrition? Autotrophs or producers Plants and other organisms that make their own food from inorganic substances Auto = itself + trophs = to eat Examples: plants (trees, bushes, ferns, etc.) and some bacteria Fern Objective: Understand Trophic Relationship among Organisms Key Words: Autotrophs, Producers, Heterotrophs, Consumers. Tree Bush Bacteria algae

3. What are Autotrophic and Heterotrophic nutrition? Heterotrophs or consumers Organisms that cannot make their own food and must obtain it ready-made. Hetero = others + trophs = to eat Example: animals, fungi, protozoa or protist, some bacteria Protozoa or Protist Bacteria Objective: Understand Trophic Relationship among Organisms Key Words: Autotrophs, Producers, Heterotrophs, Consumers. Fungi Swan

6.  Heterotrophs that eat other animals  Examples: Snakes, frogs, raccoons, hawks. What are Secondary Consumers or Carnivores? Objective: Understand Trophic Relationship among Organisms Key Words: Secondary Consumers, Carnivores. Raccon Hawk Frog

7.  Heterotrophs that eat secondary consumers  Examples: eagles, sharks, lions, owls, snakes, lizards. Bald eagle What are High-level Consumers? Objective: Understand Trophic Relationship among Organisms Key Words: High-level consumers Lizard Mountain lion Owl

8.  Organism that consumes dead organisms and organic wastes.  They break down organic molecules into inorganic molecules (water, minerals, …)  They RECYCLE dead organisms.  Examples: bacteria, fungi What are Decomposers? Objective: Understand Trophic Relationship among Organisms Key Words: Decomposers BacteriaFungi

11. A grassland is a grassy, windy, partly-dry biome, a sea of grass. Almost one-fourth of the Earth's land area is grassland. Deep-rooted grasses dominate the flora in a grassland; there are very few trees and shrubs in a grassland, less than one tree per acre. There are many different words for grassland environments around the world, including savannas, pampas, campos, plains, steppes, prairies and veldts. The climate is temperate and tropical, with a rainfall average from 25 to 75 cms a year. The natural vegetation of the grasslands includes many species of grasses and wild flowers. In areas near rivers, the vegetation may dense and include various shrubs. Animals of the grasslands include: coyotes, squirrels, antelope, grasshopper, bison, owls, birds,… In Africa, the grasslands are populated by zebras, giraffes, gazelles, lions,… Objective: Understand Trophic Relationship among Organisms Key Words: Abiotic, biotic factors, heterotrophs, autotrophs 4. Read the following paragraphs describing a specific ecosystem. Find the biotic and abiotic factors, and the different populations and communities that form that ecosystem. Classify living things as producers, consumers, primary consumers, secondary consumers, high level consumers and decomposers.
