According to Life123, temperature affects heart rate in ectothermic organisms because they depend on their environment and temperature-controlling systems to determine their own temperature and heart rate. In general, colder temperatures result in lower heart rates and warmer temperatures result in higher heart rates.Know More
Ectothermic organisms move slowly early in the morning. The organism's body temperature is cooler in the morning, which causes its heart rate to be slower. This is due to the cooler atmospheric temperatures the organism is exposed to during the night. As the day moves on, and atmospheric temperatures rise, the ectothermic organism's heart rate increases as the organism's temperature increases. As a result, the ectothermic organism moves around more during the day while temperatures are warmer, notes Life123.
Life123 states that it is hard for ectothermic organisms to regulate their body temperature. It is much more complicated than simply sitting in the sun to warm up or sitting in the shade to cool down. The environment is the leading factor in controlling the temperature of ectothermic organisms. When the weather is not suitable for these organisms, many of them use behavioral techniques to help control their body temperature since these types of organisms do not sweat.Learn more about Zoology
Kingdom Protista includes mostly unicellular, eukaryotic life forms that behave similar to animals, plants and fungi based upon how the organisms obtain nutrition from their environment. These creatures do not fit into other kingdoms of life, mostly live in water and have a nucleus in their cells.Full Answer >
A frog's heart rate can be anywhere from 40 to 50 beats per minute. Frog's are tailless amphibians. Like lizards, their hearts have three chambers, not four.Full Answer >
A person's resting heart rate is his number of heartbeats per minute during periods of inactivity or relaxation. The typical resting heart rate for an adult is between 60 and 100 beats per minute, according to the American Heart Association.Full Answer >
As listed by Medline Plus, the average resting heart rate for toddlers between the ages of 1 and 2 ranges from 80 to 130 beats per minute. About.com Pediatrics further explains that this rate is dependent on factors such as the toddler's activity level.Full Answer >
