component	living or nonliving	effect of reduced amount
soil
fish
tall plants

1. choices to place in the correct square for question 22: living, nonliving, more available food, less available food, more available nesting space, less available nesting space.

Explanation:

1. Insects and larvae: These are living organisms that serve as food for birds. A reduction means less food for birds.
2. Soil: This is a nonliving abiotic component that supports plant growth; fewer plants mean less bird food/nesting, but directly, reduced soil limits plant-based resources for birds.
3. Fish: These are living organisms that are a food source for birds. A reduction leads to less available food.
4. Tall Plants: These are living organisms that provide nesting space for birds. A reduction means less nesting space.

Answer:

Component	Living or Nonliving	Effect of Reduced Amount
Soil	NONLIVING	LESS AVAILABLE FOOD/NESTING RESOURCES
Fish	LIVING	LESS AVAILABLE FOOD
Tall Plants	LIVING	LESS AVAILABLE NESTING SPACE
