Final answer:
The option that is not an example of predation is 'b) A tree absorbing sunlight,' which represents photosynthesis, not the consumption of one organism by another like the other options listed.
Step-by-step explanation:
The question you've asked is related to understanding predation, which is a biological interaction where a predator hunts and consumes its prey. Looking at the options given in the question, the choice that is not an example of predation is 'b) A tree absorbing sunlight'.
This is because predation involves the consumption of one living organism by another, and trees absorbing sunlight is a process of photosynthesis, not predation. Other options such as a lion hunting a zebra, a snake catching a mouse, and a spider trapping a fly are all clear examples of predators actively hunting or capturing their prey, therefore demonstrating predation.
Predation is a significant ecological interaction contributing to energy transfer in food chains and food webs, and it can involve organisms with certain traits like camouflage, speed, and heightened senses to be effective hunters or to escape predators.
