Accepted Answer

Running at 10 miles per hour typically requires more energy and thus a higher metabolic rate compared to the other activities listed.

Question 2

Foraging birds typically fuel this activity by

Foraging birds primarily rely on aerobic mechanisms, which use oxygen to convert substrates like fats and carbohydrates into energy, suitable for sustained activities like foraging.

Question 3

Studies on energy costs of routine daily activity of animals focus on aerobic ATP production because

Accepted Answer

Routine daily activities in animals are primarily sustained by aerobic metabolism, as it is more efficient and sustainable for long-term energy production compared to anaerobic processes.

Question 4

A monitor placed on or in a study animal that stores data is called a

Accepted Answer

A data logger is a device that records data over time or in relation to location, often used in research to monitor study animals.

Question 5

A monitor placed on or in a study animal that transmits data is called a

Accepted Answer

Question 6

In an experiment in which an animal is injected with deuterium and oxygen-18 (D₂¹⁸O method) and then released into the wild, which of the following trends would you expect to see from measurements taken after a period of rest and again after a period of exercise?

Accepted Answer

The answer of In an experiment in which an animal...

Question 7

Which behavior represents the smallest component per unit time of the average daily metabolic rate (ADMR)?

Accepted Answer

Sleeping in the shade represents the lowest energy expenditure per unit time compared to active behaviors like chasing prey, avoiding predators, or standing guard.

Question 8

If an animal spends 3 hours a day chasing a prey (49 kJ/hr) and 20 hours a day resting (using 15 kJ/hr), its total daily cost of behavior in kJ is

Accepted Answer

The total daily cost is calculated by adding the energy spent chasing prey (3 hours x 49 kJ/hr = 147 kJ) and the energy spent resting (20 hours x 15 kJ/hr = 300 kJ), resulting in 447 kJ/day.

Question 9

If an animal spends 3 hours a day running away from a predator and 20 hours a day resting (using 20 kJ/hr), the total daily cost of behavior is 700 kJ. The kJ spent per hour running away from a predator is _______ kJ/hr.

Accepted Answer

The answer of If an animal spends 3 hours a...

Question 10

If an animal spends 6 hours a day chasing prey (50 kJ/hr) and 18 hours a day resting (10 kJ/hr), its average hourly cost of behavior is _______ kJ/hr.

Accepted Answer

The average hourly cost is calculated by taking the total energy expenditure for the day and dividing it by 24 hours. The animal spends 6 hours chasing prey (6 * 50 kJ = 300 kJ) and 18 hours resting (18 * 10 kJ = 180 kJ). The total energy expenditure is 300 kJ + 180 kJ = 480 kJ. Dividing by 24 hours gives an average of 20 kJ/hr.

Question 11

The average daily metabolic rate (ADMR) refers to the amount of energy expended _______ in their natural habitat.

Accepted Answer

The average daily metabolic rate (ADMR) refers to the energy expended by animals during their routine daily activities in their natural habitat, not just during specific activities like chasing prey or avoiding predators.

Question 12

The relationship between average daily metabolic rate (ADMR) per unit of body weight and body size is a(n)

Accepted Answer

The average daily metabolic rate per unit of body weight typically decreases as body size increases, indicating an inverse relationship.

Question 13

Which animal would display a U-shaped curve of oxygen consumption per unit of time relative to speed?

Accepted Answer

The answer of Which animal would display a U-shaped curve...

Question 14

Based on the study done by Taylor et al. (1970), the animal whose rate of oxygen consumption relative to its running speed creates a linear plot is a

Accepted Answer

The study by Taylor et al. (1970) found that the ground squirrel's rate of oxygen consumption relative to its running speed creates a linear plot, indicating a direct proportionality between these two variables.

Question 15

As a human runs faster, her metabolic rate

Accepted Answer

As a human runs faster, their body requires more energy to sustain the increased activity, leading to an increase in metabolic rate to meet the energy demands.

Question 16

Which rate would allow an animal to continue walking for the longest period of time?

Accepted Answer

A lower energy expenditure rate (15 kJ/min) would allow an animal to sustain activity for a longer period, assuming energy reserves are limited.

Question 17

The speed that _______ the cost of transport is the speed that _______ the distance that can be traveled with a given amount of energy.

Accepted Answer

Minimizing the cost of transport involves maximizing the distance traveled with a given amount of energy, as this increases efficiency.

Question 18

Which rate would be most advantageous for a fish trying to swim for the longest period of time?

Accepted Answer

A slower swimming rate, such as 1 m/h, would be most advantageous for a fish trying to swim for the longest period of time because it conserves energy, allowing the fish to sustain its swimming for a longer duration.

Question 19

For animals of any given body size, engaging in their primary form of locomotion, which activity would be the most energetically costly to cover a long distance?

Accepted Answer

Running at a high speed is generally the most energetically costly form of locomotion for animals of a given body size over long distances due to the high energy expenditure required to maintain speed and overcome friction and gravity.

Question 20

For animals of any given body size, engaging in their primary form of locomotion, which is the least energetically costly way to cover a long distance?

Accepted Answer

Swimming in fish is generally the least energetically costly form of locomotion for covering long distances due to the buoyancy of water reducing the energy required to support the body.
