b. temperate deciduous forests, then taiga, then tropical rain forests, then savanna
c. taiga, then desert, then tundra
d. tropical rain forests, then deserts, then deciduous forest, then taiga, then tundra

1. a biome dominated by coniferous plants, heavily organic soils, sometimes containing deep permafrost, and cold annual temperatures is called the ______

a. temperate forest
b. taiga
c. chaparral
d. grassland

1. the place that provides for an animal’s needs is called

a. habitat
b. community
c. ecosystem
d. niche

1. north carolina lies in the ______ biome

a. tropical rainforest
b. coniferous forest
c. grassland
d. temperate deciduous forest

1. which interaction of a biotic and an abiotic factor can help stabilize a forest area in north carolina? (look for the answer with an abiotic and biotic factor that would help an ecosystem)

a. decreased water salinity, reducing biodiversity of animals in the area
b. increased precipitation, reducing soil erosion in the area
c. decreased number of predators, allowing the number of prey to increase in the area
d. increased decaying organic material, adding nutrients to soil in the area

1. which is a biotic factor that could affect an ecosystem?

a. bacteria harming the health of organisms in an ecosystem
b. dust storms moving through an ecosystem
c. large amounts of acid rain precipitation seeping into the soil in an ecosystem
d. high levels of carbon dioxide entering the atmosphere within an ecosystem

Explanation:

Question 1

To determine the correct order of biomes from the equator (0° latitude) to the North Pole (90° N latitude), we analyze the climate and biome distribution:

• At the equator, tropical rainforests (high rainfall, warm temperatures) are found.
• Moving north, deserts (arid, less rainfall) occur due to descending air masses.
• Next, temperate deciduous forests (moderate climate, seasonal changes) are present.
• Then, taiga (coniferous forests, cold climate) is found.
• Finally, at the North Pole, tundra (cold, treeless, permafrost) exists.

Option A is incorrect as tundra is at the pole, not near the equator. Option B has incorrect order (temperate deciduous forests are not near the equator before tropical rainforests). Option C is incorrect as taiga is not near the equator and desert is not after taiga. Option D follows the correct sequence: tropical rain forests (equator), then deserts, then deciduous forest, then taiga, then tundra (North Pole).

We analyze the characteristics of each biome:

• Temperate forest: Has deciduous trees, moderate climate, no permafrost.
• Taiga: Dominated by coniferous plants, has heavily organic soils, sometimes deep permafrost, and cold annual temperatures.
• Chaparral: Dense, evergreen shrubs, Mediterranean climate.
• Grassland: Dominated by grasses, few trees.

The description matches the taiga biome.

We define each term:

• Habitat: The place where an animal lives and gets its needs met.
• Community: A group of different species in an area.
• Ecosystem: Includes biotic and abiotic factors in an area.
• Niche: The role an organism plays in an ecosystem.

The question asks for the place providing for an animal’s needs, which is a habitat.

Answer:

D. tropical rain forests, then deserts, then deciduous forest, then taiga, then tundra
