Question

select all the correct answers.
in a garden with trees and shrubs, green and pink katydids were observed. over time, birds started feeding on the katydids. which two statements describe what will eventually happen to the population of the katydids?
the population of pink katydids will decrease.
the population of green katydids will decrease.
the population of mean katydids will increase

Explanation:

1. Camouflage and Predation Principle: In a garden with green trees and shrubs, green katydids can camouflage better (blend with the environment) than pink katydids. Birds (predators) will more easily spot and feed on pink katydids.
2. Effect on Populations:

• For pink katydids: Since they are more visible to predators, their survival rate decreases, so their population will decrease.
• For green katydids: Their camouflage helps them avoid predation more effectively, so their survival and reproduction rates are higher, meaning their population will increase (not decrease). The option "The population of green katydids will decrease" is incorrect. The option about the population of pink katydids decreasing is correct, and the (partially visible) option about the green katydid population increasing (assuming the third option is "The population of green katydids will increase") would also be correct. But from the visible options, "The population of pink katydids will decrease" is correct, and if there's an option about green increasing, that's also correct. Assuming the three options are (1) The population of pink katydids will decrease, (2) The population of green katydids will decrease, (3) The population of green katydids will increase:
• Option 1: Correct (pink is visible, predation reduces their numbers).
• Option 2: Incorrect (green camouflages, predation is less, population should increase or stay stable, not decrease).
• Option 3: Correct (green avoids predation, so population grows).

Answer:

(Assuming the options are labeled as follows, with the correct ones):

• The population of pink katydids will decrease (correct).
• The population of green katydids will increase (correct, if that's an option).

(If the third option is misprinted but the visible correct ones are the pink population decrease and green population increase, those are the answers.)
