Document Summary
12 exam questions slide 1: slide 2: where he comes from: low species biodiversity contrast to areas where he travelled to high species diversity. Boy is this different than in the uk. Animal- animal, plant- animal etc abiotic factors are those involving physical fctors of environment. Year round warmth results in rapid growth and insect/ microbial populations. Pest and disease pressures on plants more intense. Species diversity is high so distance from one indididual to another could be several kilometers. Wind in tropics isn"t important, instead its animals that do pollination. Tropical forests are also largely evergreen ( non deciduous) unlike temperate forests. Dense canopy in tropical forest makes it harder for pollen to get transported by wind. Dan janzen found that the euglossine bee as long distance pollinator of tropical plants. Bees can travel 23 km between similar species of plants in a tropical forest.
