Compare responses of named Australian ectothermic and endothermic organisms to changes in the ambient temperature and explain how these responses assist in temperature regulation

- ECTOTHERMS atomic number 18 organisms that have a limited ability to jibe their body temperature. Their cellular activities generate little heat. Their body temperatures climbing and f all in all with ambient temperature changes. Most organisms are ectotherms. Examples are plants, all invertebrates, fish, amphibians and reptiles

- ENDOTHERMS are organisms whose metabolism generates enough heat to maintain an inseparable temperature independent of the ambient temperature. Examples are birds and mammals

- EXTENSION (Not really postulate but any look...)

Poikilotherms are animals whose body temperatures are always changing. reliable poikilotherms have temperatures that are the same as the environment. An example is jellyfish. Poikilothermy is lots assumed to be the same as ectothermy; however, this is incorrect. Some ectotherms, analogous snakes, can regulate their temperatures using behaviour to maintain a stable temperature.

Homeotherms are animals with stable body temperatures. Most endotherms are also homeotherms.

The poikilotherm/homeotherm classification body was based on the stability of the body temperature of the organism. This system is now redundant.

The ectotherm/endotherm system uses the organisms source of body heat as a way of classification. This system is accepted today.

- BEHAVIOURAL ADAPTATIONS:

Migration: Animals can move to stay off temperature changes. Many birds that spend spring and summer in Australia transmigrate before the temperature becomes cold.

Hibernation: To survive cold conditions, many animals hibernate; that is they lie in a sheltered spot, their metabolism slows and the body temperature drops. aestivation is the hibernation of organisms in heat conditions. Bogong moths migrate to spend the summer months in caves in the Australian Alps

Shelter: Animals seek shelter to avoid complete conditions. They can dig burrows or seek shelter in caves or crevices. They can shelter to avoid high temperatures or avoid low temperatures. An example is the central netted dragon

Nocturnal operation: Brown snakes can change into nocturnal animals when...
