To determine what happens to the other members of the food chain when the cat, which is likely a predator in this scenario, is removed, we need to consider the roles of the organisms involved.
If the cat is removed:
- The population of its prey (such as birds and snails) is likely to increase since they are no longer being hunted by the cat.
- With more birds and snails, the plants that they feed on could see an increase in grazing pressure, but the overall population of plants might increase due to less predation on the herbivores.
Looking at the options given:
- **A. The number of plants, snails, and birds increase.** (This is plausible.)
- **B. The number of plants and snails increase and the number of birds decreases.** (This doesn't make sense as the birds would likely increase.)
- **C. The number of plants increases and the number of snails and birds decrease.** (This contradicts the expected increase in prey populations.)
- **D. The number of plants and birds increase and the number of snails decreases.** (This is also unlikely since the snails would probably increase rather than decrease.)
Given this analysis, the correct option is:
**A. The number of plants, snails, and birds increase.**
