Question

Signal Options: Visual, Low frequency sound, High frequency sound, chemical cue

What signal is most appropriate for each ecological context below:

1. A signal that should be quickly detectable by animals through a mile of forest

2. A signal detectable only to nearby dark forest dwellers

3. A signal that will persist at territory boundaries

4. A constant signal of distatefulness that will deter dirunal predators

Answer 1

1. A signal that should be quickly detectable by animals through a mile of forest is Low frequency sound.

Explaination: Low frequency sound can travel long distance without being effected by any obstacles on its way, this sound pitch is less than that human can hear.

2. A signal detectable only to nearby dark forest dwellers is High frequency sound.

Explaination: High frequency sound is used by forest tribes for their communication in darkness as it is more effective.

3. A signal that will persist at territory boundaries is Chemical cue signal.

Explaination: Chemical signal may be a smell it is confined to a particular boundary.

4. A constant signal of distatefulness that will deter dirunal predators is visual signal.

Explaination: In day time visual signals are higly recognizable by animals to determine predators.
