PPT-Exploring Terrestrial & Aquatic Biomes

Overview Discovering Ecology Ecology is the scientific study of the interactions between organisms and the environment These interactions determine distribution of organisms and their abundance.

Vocabulary. Ecology. – study of interactions that take place b/t organisms and their environment. Abiotic. factor . – non living parts of an organisms environment (i.e. rocks, air currents). Freshwater Biomes. Freshwater is less than 3% of the Hydrosphere. . 90% of the freshwater is locked beneath the Earth’s surface. . Water is cycled through evaporation and transpiration from the atmosphere to the land and back again. . “Ecology is no. thing”. I. Definition. :. Organisms. Populations. Communities. Ecosystems. II.

This biome is the driest; it only receives 50cm of rainfall a year about 10% of the rainfall in the rainforest. Its plants and animals have to survive in an environment with little water and dramatic temperature changes from day to night. Some animals and plants may find if difficult to adapt, but reptiles and cacti thrive in these conditions.. 97% oceans. 2% glaciers. 1% lakes, rivers, streams. Precipitation. over land.

Elephant populations in southern Africa declined sharply due to hunting but have made overwhelming comebacks within nature reserves and parks.. Some worry that elephant overpopulation is causing a decline in local biodiversity and damage to farms and infrastructure.. A BIG group of LIVING things . Different kinds of species.
