Terrestrial BiomesIV. Aquatic BiomesClicker QuestionsWhat is contributing to the loss of vultures and the surge of rabies?a. It doesn’t matter they’re only vultures after all b. New strains of the rabies virusc. Climate changed. An anti-inflammatory drug given to cattleIf the climate/ environment of the pronghorn changed from grassland to a forest land, would hiscurrent adaptations be useful?a. Yes, the pronghorn would still be successful in a forestland. For example, his speed would still allow him to escape predators. b. No, the pronghorn’s grassland adaptations would not be useful in a forest.Biotic and Abiotic FactorsOrganisms are adapted to the biotic and abiotic factors by natural selection- Pronghorn (deer) highly successful herbivorous running mammal of open countryo Coat keeps him warm in winter o Coat hair stands up in summer so he stays coolo Awesome for extreme temperature fluctuationso Very fast runner (up to 60 mph)Regional climate influences the distribution of terrestrial communitiesTerrestrial Biomes- Solar radiation varies with latitudeBiology 102o Most climatic variations are due to the uneven heating of Earth’s surface- The tilt of Earth’s axiso Causes the changes of the seasons in the northern and southern hemispheres- Uneven heating causes rain and winds - Ocean currentso Created by winds, planet rotation and location of continentsAquatic BiomesOceans occupy 75% of Earth’s surface- Intertidal zone, an oceanic zoneo Is the area of shore where the ocean meets the landWhen the tide comes in it’s covered by water when its low tide, there’s no water covering it, it’s dryo Estuary- ocean (salt) meets river (fresh)- Photic zoneo Where the continental shelf is Coral reefs Photosynthesis occurs here Where submerged parts of the continent
