In this food web, secondary consumers would increase in number if snakes were eliminated.
Option D
Step-by-step explanation:
The food web consists of producers (photosynthetic) which are plants like cactus, grass, algae, and phytoplankton the organisms that eat these plants are known as primary consumers. These consumers are herbivores i.e., vegetarians like deer, rabbits, cow, sheep and the organisms that eat the herbivores are carnivores i.e., the meat-eaters who are called secondary consumers.
Those who eat these organisms are known as tertiary consumers (carnivores). Thus this forms a food web of each organisms. Since snakes who are tertiary consumers were to be eliminated, the increase in secondary consumers like lizard, mouse, fish will happen.
