Question

1. label the axes of this figure, and identify each biome shown here. try to do this based on your understanding of the figure, and then use the text to check your answers. you will use these biomes: temperate grassland, temperate broadleaf forest, tropical forest, northern coniferous forest, desert, tundra.

figure with graph and three small images

1. describe each major terrestrial biome as to rainfall, temperature, location, and representative flora and fauna.

tropical forest

desert

savanna

Explanation:

For Question 18:

Step1: Determine Axes

Biome graphs typically use temperature (y - axis, often average annual temperature) and precipitation (x - axis, often average annual rainfall) as axes, since these are key abiotic factors defining biomes.

Step2: Identify Biomes (General Approach)

• Tropical Forest: High temperature (near equator - like temps) and high precipitation. In the graph, the region with highest temp and high rainfall.
• Desert: Low precipitation (x - axis low) and variable temp (can be high or low, but aridity is key). The narrow region with low rainfall.
• Tundra: Low temperature (y - axis low) and low - moderate precipitation. The region with lowest temp.
• Temperate Broadleaf Forest: Moderate temperature and moderate - high precipitation.
• Northern Coniferous Forest (Taiga): Cooler temperature than temperate broadleaf, moderate precipitation.
• Temperate Grassland: Moderate temperature, moderate - low precipitation (less than forests, more than deserts in some cases).

For Question 19 (Tropical Forest, Desert, Savanna):

Tropical Forest:

• Rainfall: High (200 - 400 cm/year, or more), relatively constant.
• Temperature: Warm (20 - 25°C year - round), little variation.
• Location: Near the equator (e.g., Amazon, Congo Basin, Southeast Asia).
• Flora/Fauna: Flora - Diverse trees (broadleaf evergreens), epiphytes, lianas. Fauna - Monkeys, sloths, colorful birds, insects, amphibians (high biodiversity).

Desert:

• Rainfall: Very low (less than 30 cm/year, often sporadic).
• Temperature: Extreme (hot deserts: up to 50°C in day, cold at night; cold deserts: cool overall).
• Location: 30°N/S of equator (e.g., Sahara, Mojave, Gobi).
• Flora/Fauna: Flora - Succulents (cacti), drought - resistant shrubs. Fauna - Desert foxes, lizards, snakes, insects (adapted to aridity).

Savanna:

• Rainfall: Moderate (30 - 150 cm/year), with distinct wet/dry seasons.
• Temperature: Warm (20 - 30°C, little annual variation).
• Location: Tropical regions (e.g., Africa’s Serengeti, parts of South America, Australia).
• Flora/Fauna: Flora - Grasses (tall, drought - tolerant) with scattered trees (acacia, baobab). Fauna - Grazers (zebras, wildebeest), predators (lions, cheetahs), termites.

Question 18:

• Axes: Y - axis: Average Annual Temperature (°C); X - axis: Average Annual Precipitation (cm).
• Biome Identification (General):
• Largest/highest temp + high rain: Tropical Forest.
• Low rain, variable temp: Desert.
• Lowest temp: Tundra.
• Moderate temp + moderate - high rain: Temperate Broadleaf Forest.
• Cool temp + moderate rain: Northern Coniferous Forest.
• Moderate temp + moderate - low rain: Temperate Grassland.

Question 19:

Tropical Forest:

Rainfall: High (≥200 cm/yr, constant).
Temperature: Warm (20–25°C, stable).
Location: Equatorial (Amazon, Congo, SE Asia).
Flora/Fauna: Diverse trees, epiphytes; monkeys, sloths, birds.

Desert:

Rainfall: Very low (<30 cm/yr, sporadic).
Temperature: Extreme (hot: 50°C day/ cold night; cold: cool).
Location: 30°N/S (Sahara, Mojave, Gobi).
Flora/Fauna: Succulents, drought - shrubs; desert foxes, lizards.

Savanna:

Rainfall: Moderate (30–150 cm/yr, wet/dry seasons).
Temperature: Warm (20–30°C, stable).
Location: Tropical (Serengeti, S. America, Australia).
Flora/Fauna: Tall grasses + scattered trees; zebras, lions, termites.
