| Question | Answer |
| Habitat | Home for organisms, provides food, shelter, water and temp needed for survival |
| Biome | large geographic areas with similar climates and ecosystems which inclue tundra, taiga,temperate deciduous forest, rainforest, grassland, desert. |
| Micro Habitat | tiny place or home that provides food, shelter, water and temp needed for living |
| Organism | a thing that is alive, a living thing |
| Biotic | living factors or components such as plants and animals |
| Abiotic | non living factors or components such as light, water, soil, temp, air, rocks,etc. |
| Biodiversity | the existance of a wide variety of species in an ecosystem or biome. |
| Contribute | to give or play a part in bringing about an end or result |
| Sustainability | the ability to support and withstain over time |
| Ecosystem | all the interactions of organisms with each other as well as their environment |
| Ecological Succession | the normal, gradual changes in the types of species that live in an area over time |
| Pioneer Species | first organisms such as lichens, mosses, ferns that come to an area but do not require soil. |
| Primary Succession | The process of ecological succession that begins in a place without soil and life, only rock. ex: volcanic island |
| Secondary Succession | succession that begins in a place that already has soil and once had living things. ex: forest fire |
| Lichens | symbiotic relationship between a fungus and an alga or bacteria and alga |
| tundra | coldest, cold, dry, ice, permafrost, north pole, polar bears, lichen, mooses, caribou |
| taiga | snowy, cold winters, warmer summers, evergreen trees, bears,wolves, lynx |
| temperate deciduous forest | 4 distinct seasons, plenty of rainfall, decidous trees such as maple, oak, chery |
| grasslands | adequate rain grasses, grains, cattle, sheep, zebra, lions, wildebeast |
| desert | driest, very little rain, hot, cacti, snakes, lizzards |
| rainforest | warm, wet high biodiversity due to many layers of habitats, near equator |
| plants in tundra | lichens, mosses, grasses, very small shrubs |
| permafrost | permanently frozen soil below the thawed surface layer |
| tundra plants are usually small | soil has few nutrients,cold temp,short growing season, plant roots can't break thru or penetrate frozen soil |
| which biome has the greatest biodiversity? | tropical rainforest |
| Why does the number of pioneer species in an area decrease after time and ecological succession? | the larger, stronger plants over come the weaker ones. |
| Does succession work to return | |
