○ food, shelter, air
○ food, family, mates
○ food, air, mates

Explanation:

First Question (Difference between biotic and abiotic factors)

To solve this, we recall the definitions: Biotic factors are living or once - living components of an ecosystem (like plants, animals, bacteria), and abiotic factors are non - living components (like temperature, water, sunlight, soil). Now let's analyze each option:

• Option 1 (assuming the first option has a typo but the correct idea: Biotic factors are living things and abiotic factors are non - living things): This matches the definitions.
• Other options: They have incorrect pairings (e.g., saying biotic is non - living or abiotic is living which is wrong).

In an ecosystem, the basic needs for which organisms compete include food (for energy), shelter (for protection), and water (for various physiological processes). Let's analyze the options:

• Option "food, shelter, water": Food, shelter, and water are all essential non - living (abiotic) or resources related to survival that organisms compete for.
• "food, shelter, air": Air is generally not a limited resource that organisms compete for in the same way as food, shelter, and water.
• "food, family, water": Family is not a basic need for which organisms compete in the context of community interactions for survival resources.
• "food, air, water": Again, air is not a typical resource for competition as it is usually abundant.

Answer:

The option that states "Biotic factors are living things and abiotic factors are non - living things" (assuming the first option was meant to have this correct description, as per the context of biotic - abiotic definitions).
