Biomes, Ecoregions and Sustainability http://www.neok12.com/php/watch.php?v=zX0215667004445d05420545&t=Ecosystems
Why do we find different plants and animals in different biomes? • Plants and animals are adapted to live in their biome. They live within that certain climate.
Biodiversity contributes to sustainability of an ecosystem. • Sustainability means an ecosystem can continue over a long period of time • The healthier and more diverse an ecosystem is, the more sustainable it is
What are some biotic components shared by most biomes? • plants • insects • herbivores • carnivores • omnivores • scavengers • decomposers
What are some abiotic components shared by most biomes? • light • weather • soil • precipitation • temperature
What adaptations help organisms survive in different biomes? • Eating adaptations like teeth, claws, talons, speed, ability to fly • Reproductive adaptations like bright feathers, a pouch, noises • Hiding adaptations like camouflage • Protective adaptations like heavy fur, blubber, toxins or venom
How do adaptations help different organisms survive in different biomes? • Most adaptations help the organisms survive in it’s own biome and the conditions that exist there
How do different environments help to support different varieties of organisms? • The environment should supply food, shelter, water etc… • The organisms that are adapted to live in those conditions will survive
Would a microhabitat, such as the yard around the school, help to support organisms the same way a biome would? • There should be life in the yard because all of the basic essentials for life are there.
What are some of the relationships between biomes? • Sometimes certain plants and animals can live in more than one biome.
Could an organism from one biome adjust quickly to the conditions of another biome? • Not usually. They would not be adapted to another biome.
Biome Comparison • With the other students at your table, pick two biomes that are similar to each other. • Complete a Venn diagram comparing the two biomes. Abiotic and biotic factors they have in common Abiotic: Weather, landforms or other abiotic characteristics that the two biomes do NOT share Biotic: plants and animals that the two biomes do NOT share
Biome Comparison • Now pick two biomes that are very different from each other. • Complete a Venn diagram comparing the two biomes. Abiotic and biotic factors they have in common Abiotic: Weather, landforms or other abiotic characteristics that the two biomes do NOT share Biotic: plants and animals that the two biomes do NOT share
Think back to our demonstration with the paper squares. • When there is little biodiversity in an ecosystem________________________. • When there is more biodiversity in an ecosystem ________________________.
How does the variety of species within an ecosystem maintain equilibrium? • The more variety in an ecosystem, the easier the organisms can recover if there is a change in the environment
Frogs • How would the ability to jump affect your survival? • How does genetic variation affect the population?
Biomes and Ecoregions • With your table partner, pick one of the biomes you researched. • Decide which Texas Ecoregion from earlier in the year is the MOST similar to your biome. • Create a quick chart showing the similarities between the biome and the ecoregion.
Ecoregions Biomes • Pineywoods • Oak Woods • Trans Pecos • Gulf Coast Marshes • High and Rolling Plains • Edwards Plateau/Llano Uplift • Desert • Grassland • Deciduous Forest • Boreal Forest • Mountains • Marine
