1)
Which of the following characteristics are generally associated with the foraging mode of an organism?
Reproductive effort
Risk of predation
Locomotor mode
All the above
2)
An organism with a sit-and-wait foraging strategy is mostly relying on
Moving preys
High prey density
All the above
None of the above
3)
What is the effect of size of the foraging area on the energy spent in waiting and pursuit of the prey?
Increasing the size of the foraging area increases the average time and energy spent in capturing the prey
Increasing the size of the foraging area increases the time and energy spent in waiting for a prey
Both of the above
No relation between size of the foraging area and waiting time and energy spent
4)
When compared with searching predators, the energetic requirements of sit-and wait predators should be _____________
Higher
Lower
5)
The total ‘energy gain’ is denoted by
