Imagine that a lizard inhabits a desert where it has very few natural predators. During a year when resources are scarce, the lizard produces a handful of large eggs rather than several small eggs. This is an example of:

Trade off.

Explanation:

Trade off may be defined as the condition in which one trait cannot increase without the decreasing of the another trait of the organism. Trade off proves to be beneficial as well as detrimental for the organism.

Lizard as inhabit the desert with few predators, the large eggs are produced when the resources are scarce. This is an example of trade off as the size of eggs increase as there are no natural predators and the resources are scarce in this case.

Thus, the answer is trade off.
