The process is essential for recycling the finite matter that occupies physical space in the biome. Decomposition (or rotting) is the process by which organic substances are broken down into simpler forms of matter. The process is essential for recycling the finite matter that occupies physical space in the biome. Fruits Vegetables Meat Dairy Bread and Grain In ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Prey is simply the animal that gets attacked by the predator. Sunlight Temperature is affected by the Sun Hot Cold Air/Atmosphere gases Carbon dioxide and oxygen availability UV Radiation Moisture and Humidity Can be determined by the Sun Climate Photosynthesis &
Chemosynthesis Can be determined by the Sun Photosynthesis depends on the sun Natural Elements Fire Water Lakes Rivers Ponds Salt Water Earth Dirt Rock Soil Sand Mountains Clouds Lightning Affected by altitude and elevation Seasons Summer Winter Spring Fall TEMPERATURE Summer can be well over over 38 degrees C, while winter can be as low as -40 degrees C. PRECIPITATION Annual Average is about 50.8-88.9cm. The range is very large over the course of the year. ABIOTIC FACTORS -warm to hot summers
-moderate seasonal precipitation
-occasional fires BIOTIC FACTORS -Grassland plants
-dispersal of seeds by wind
-open exposed environment
-camouflage & burrowing FUN FACT The Marine Biome is the biggest biome in the world covering 70% of the Earth! TEMPERATURE The average of all oceans is about 4 degrees Celcius. PLANTS Over 1 million species of plants and animals have been discovered and scientists say there may be as many as 9 million species that still haven't been found. ANIMALS -mollusks
-sea anemones Depths of the Ocean Omnivores Omnivores Insectivore Herbivore Omniovre Carnivore To shape ecosystems lightning strikes things and starts fires. Herbivore Shapes ecosystems by controlling plantlife. Clouds emit precipitation and plants benefit from the rain. Clouds can also block the sun. Herbivore Omnivore Insectivores or Herbivores
