Document Summary

Aric aquaic ecosystem is ice, ice caps, glaciers, sea ice etc. Many animals and plants up there have adjusted to the life in such an icy climate. Home to musk ox, aric fox, caribou that stay acive in winter ime and maintain a body temp of. 37 c whilst the environment is -60 c. some animals hibernate and drop body temp to just above freezing. Plants face low temps and short growing season. Animals that generate their own internal heat are called endotherms (meaning inside heat) (warm blooded vertebrates such as mammals and birds). Repiles cannot be endotherms as they can"t maintain internal body temperatures through metabolic processes. Animals like ishes (amphibians, repiles, and invertebrates) that rely on environmental sources of heat are called ectotherms (outside heat). Ectotherms body temp is idenical to environment they are in. By siing in sun animals like repiles can warm up body temp. Populations: climate change may affect survival, growth and reproduction.
