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.

Sustainability

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 have you learned that you didn’t expect about biomes?

What are some interesting facts about the biomes?

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.
