Compare Responses Of Named Australian Ectothermic And Endothermic Organisms To Changes In The Ambient Temperature And Explain How These Responses Assist In Temperature Regulation

528 words - 2 pages

- ECTOTHERMS are organisms that have a limited ability to control their body temperature. Their cellular activities generate little heat. Their body temperatures rise and fall 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 internal temperature independent of the ambient temperature. Examples are birds and mammals- EXTENSION (Not really needed but anyway...)Poikilotherms are animals whose body temperatures are always changing. True poikilotherms have temperatures that are the same as the environment. An example is jellyfish. Poikilothermy is often assumed to be the same as ectothermy; however, this is incorrect. Some ectotherms, like 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 system was based on the stability of the body temperature of the organism. This system is now redundant.The ectotherm/endotherm system uses the organism's source of body heat as a way of classification. This system is accepted today.- BEHAVIOURAL ADAPTATIONS:Migration: Animals can move to avoid temperature changes. Many birds that spend spring and summer in Australia migrate before the temperature becomes cold.Hibernation: To survive cold conditions, many animals hibernate; that is they remain 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 AlpsShelter: Animals seek shelter to avoid...

Instruments      A temporal scanner (TAT-5000) was used to measure temperature (Chiu et al., 2005). This scanner is highly correlated with rectal and esophageal temperatures (Chiu et al., 2005).

Adaptions in Ectothermic and Endothermic Animals to Extreme Climates

1425 words - 6 pages Adaptions in Ectothermic and Endothermic Animals to Extreme Climates First of all we need to understand what ectothermic and endothermic animals are. Animals differ in their abilities to regulate body temperature (thermoregulation). We sometimes use the terms "cold-blooded" or "warm-blooded." Most reptiles feel cold to the touch, while mammals and birds often feel warm. Somewhat more precise descriptions can be made by using the terms

Photosynthesis in Relation to Light, Temperature and Water

1662 words - 7 pages , water is the major constituent of the protoplasm of a cell. By means of turgor pressure and other changes in the cell, water regulates the opening and closing of the stomata, thus regulating transpiration. Water also provides the pressure to move a root through the soil. Among water's most critical roles is that of a solvent for minerals moving into the plant and for carbohydrates moving to their site of use or storage. By its gradual evaporation of water from the surface of the leaf, near the stomata, helps stabilize plant temperature. So, in conclusion, Light, Temperature and water all affect the rate of photosynthesis.
