Final answer:
The other members of the food chain will be affected if the garden is removed. Without garden plants, snails will have no food source, leading to a decrease in their population, which will impact the bird and cat populations.
Step-by-step explanation:
The other members of the food chain will be affected if the garden is removed. Since the garden plants are the primary producers in the food chain, their removal will disrupt the energy flow. Without the plants, the snails will have no food source, leading to a decrease in their population.
As a result, the bird population, which depends on snails for food, will also be affected. Finally, the household cat, which preys on birds, will also be impacted due to a decrease in their prey.
