3. Ecosystems The plants and animals that are found in a particular location are referred to as an ecosystem. These plants and animals depend on each other to survive. In a delicate balance, these life forms help to sustain one another in regular patterns. Disruptions to an ecosystem can be disastrous to all organisms within the ecosystem

4. Biomas Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there. A biome can be partially defined by the local climate patterns. You may also have more than one type of biome within a larger climate zone. Here is a short list of possible biomes. Tropical Rainforest (ThinkaboutBrazil)- Tropical Savanna (ThinkaboutAfrica)- Desert (Thinkaboutthemiddleeast)- Mediterranean Woodland (Thinkaboutconiferousforests)- Mid-latitudeGrassland (Thinkabout Oklahoma)- Mid-latitudeDeciduousForest (Thinkabouttheeastcoast of North America)- Tundra (Thinkaboutfrozenplains of Alaska)- Ice Caps (Thinkaboutthepoles)

5. Niches 1] is a term describing the relational position of a species or population in its ecosystem to each other; e.g. a dolphin could potentially be in another ecological niche from one that travels in a different pod if the members of these pods utilize significantly different food resources and foraging methods
