How does the average number of drops required to break open a whelk depend on platform height for a drop of 5 meters or less? For drops of more than 5 meters?

Short Answer

Expert verified

When the platform height is more, such as 5 meters or more, the drop numbers will be reduced due to their inverse relationship. When this platform height decreases, the average drop number rises.

Step by step solution

01

Food sources for animals 

Food sources can be derived synthetically or through natural means, such as plant and animal species, to support growth and provide energy to the living body.

Examples of food that birds (like crows) eat are insects, fruits, nuts, frogs, dead animals, bird eggs, stolen fish from eagles, seeds, grains, worms, and berries. The features of crow appearance are some crows having white patches on their black feathers, strong legs, and shiny feathers.

02

Ornithology

The scientific zoological branch that presents the research-based knowledge regarding bird species by collecting their preserved specimen, skin, and skeleton is called ornithology.

The several importances associated with the branch of zoology (such as ornithology) are bone structure identification of birds and ecosystem understanding to support life.

The distinct types of studies involved in ornithology are categorized as field and laboratory-based research to study bird structure and functioning.

03

Crow dropping whelk

The crow prefers larger whelk as its food, and then, the crow picks it up and flies high so that it can drop the whelk on the rock to expose its flesh.The crow tries to drop the whelk until it breaks open and then breaks its hard outer shell to obtain its exposed meat.

The average drop numbers and platform height are dependent on each other; both factors show an inverse relationship with each other.

Most popular questions from this chapter

You are considering two optimal foraging models for the behavior of a mussel-feeding shorebird, the oystercatcher. In model A, the energetic reward increases solely with mussel size. In model B, you take into consideration that larger mussels are more difficult to open. Draw a graph of reward (energy benefit on a scale of 0โ€“10) versus mussel length (scale of 0โ€“70 mm) for each model. Assume that mussels under 10 mm provide no benefit and are ignored by the birds. Also assume that mussels start becoming difficult to open when they reach 40 mm in length and impossible to open when 70 mm long. Considering the graphs you have drawn, indicate what observations and measurements you would want to make in this shorebirdโ€™s habitat to help determine which model is more accurate.

Total flight height can be considered to be a measure of the total energy required to break open a whelk. Why is this value lower for a platform set at 5 meters than one at 2 or 15 meters?

How might a learned behavior contribute to speciation? (See Concept 24.1.)

Although many chimpanzees live in environments with oil palm nuts, members of only a few populations use stones to crack open the nuts. The likely explanation is that

(A) the behavioral difference is caused by genetic differences between populations.

(B) members of different populations have different nutritional requirements.

(C) the cultural tradition of using stones to crack nuts has arisen in only some populations.

(D) members of different populations differ in learning ability.

Learning is defined as a change in behavior as a result of experience. In a short essay (100โ€“150 words), describe how heritable information contributes to the acquisition of learning, using some examples from imprinting and associative learning.
