1. what piece of climate evidence supports the fact that animals from the temperate grassland must be

able to survive in a variety of temperatures?
a. the temperate grassland has fertile soil that can support many plant species.
b. the temperate grassland has the most rainfall of any other biome.
c. the temperate grassland has a variety of temperatures due to their hot summers and cold
winters.

1. what is the one characteristic that all grasslands have in common?

a. all grasslands have warm temperatures year - round.
b. all grasslands have cold temperatures year - round.
c. all grasslands have grass as the main form of plant life.

1. one of the most unique characteristics of the temperate deciduous forest biome is the presence of autumn

(fall). during autumn in the tdf, leaves on deciduous trees change color, fall to the ground, and die. this
actually has a major impact on the tdfs soil. describe the impact of deciduous trees on the tdf soil
during autumn.
during autumn, the leaves make the soil fertile / dry because _

Explanation:

1.

Step1: Analyze option a

Fertile soil supporting plant species is about soil fertility and plant - related aspects, not about temperature variety for animals' survival.

Step2: Analyze option b

Tropical rainforests have more rainfall than temperate grasslands. So, this option is incorrect.

Step3: Analyze option c

If the temperate grassland has a variety of temperatures due to hot summers and cold winters, then animals in this biome need to be able to survive in a variety of temperatures.

2.

Step1: Analyze option a

Tropical grasslands (savannas) have warm temperatures year - round, but temperate grasslands have hot summers and cold winters. So, this is not a common characteristic.

Step2: Analyze option b

No grassland has cold temperatures year - round.

Step3: Analyze option c

By definition, grasslands are biomes where grass is the main form of plant life.

3.

Step1: Explain the process

When leaves fall from deciduous trees in autumn, they decompose. Decomposition of leaves adds nutrients such as nitrogen, phosphorus, and potassium to the soil.

Answer:

1. C. The temperate grassland has a variety of temperatures due to their hot summers and cold winters.
2. C. All grasslands have grass as the main form of plant life.
3. During autumn, the leaves make the soil fertile because when the leaves decompose, they add nutrients (such as organic matter, nitrogen, phosphorus, etc.) to the soil.
