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 | |
