Smaller birds and mammals have a higher metabolic rate than larger ones because they have a higher surface to volume ratio. That means they lose heat faster, and don't have as much body mass to generate heat. To keep their body temperature well above the temperature in their environment, they have to burn more fuel (food), breathe in more oxygen, and pump blood faster. Cold blooded animals don't show the same big differences in metabolism relative to their size.

∙ 13y agoThe rate of respiration depends on the size of the lungs and the rate of activity. Small animals do not necessarily breathe faster than large animals.

Why is pulse rate faster in small and young animals compared to that in large and older animals?
Because your heart does not pump as efficiently as it did when you were younger.
Why is it good to have a fast metabolic rate?
You can lose weight a lot faster and dissolve sugar faster.
Does cellular respiration maintain the high metabolic rate in animals?
High metabolic rate need a lot of energy. So this is supplied by respiration
Which abiotic factor has the biggest effect in the metabolic rate of animals?
tempreture
Why is a mouse pulse rate faster than an elephant pulse rate?
Mouse doesnt have a pulse rate, but it has a faster heartbeat rate coz its smaller in size,the smaller the animal is,the higher the heartbeat rate it has!!!!
WHAT DO BASAL METABOLIC RATE MEAN?
Basal metabolic rate (BMR), and the closely related resting metabolic rate (RMR), is the rateof energy expenditure by humans and other animals at rest, and is measured in kJ per hour per kg body mass.
Does Rubner's Surface Rule states that metabolic rate is affected by the ratio of surface area to volume?
The Rubner rule apples to animals that maintain their body temperature at a steady level. Their metabolic rate is approximately proportional to the surface area of the body.The Rubner rule apples to animals that maintain their body temperature at a steady level.

Do women have faster pulses than men?
Yes. Smaller animals such as the hummingbird tend to have a (much) faster pulse than bigger animals such as a beluga whale. Likewise women have a faster heartbeat because they are smaller than their male counterparts. General rule of thumb; the smaller the organism, the faster the pulse.
Why do women and children have faster breathing rate?
smaller lungs
Where can one find information on Basal metabolic rates?
A basal metabolic rate (BMR) is the amount of energy expended by humans and animals daily while at rest. To find more information, contact your family doctor to determine your basal metabolic rate.
How the size of particles affect the way the particles dissolve?
The smaller the particle the faster it dissolves. This is because the process by which a solute dissolves takes place at the surface of the solvent. That means the larger the surface area of a particle or solute, the faster the solute will dissolve.
Why do young animals breathe faster than oldre animals?
Any small animal's metabolic rate is higher/faster than the larger/bigger ones. And breathing is positively correlated with metabolism. Thus small fish breath faster than large fish.
