Question

which of the following statements about biomes is/are true? (i) biomes are often defined by abiotic factors such as temperature, climate, relief, geology, soils, and biotic factors. (ii) there are nearly eight to fourteen major categories of biomes around the world. (iii) temperate grasslands are closest to the equator. options: statements i and ii; statements ii and iii; statements i only; statements i and iii

Explanation:

• For statement (i): Biomes are defined by both abiotic (temperature, climate, etc.) and biotic factors, so this is true.
• For statement (ii): The number of major biome categories ranges around 8 - 14, so this is true.
• For statement (iii): Tropical biomes (like tropical rainforests, savannas) are closest to the equator, not temperate grasslands. So this is false.

So statements I and II are true.

Answer:

Statements I and II
