APES Unit 1 Review

Which of the following best defines an ecosystem and identifies its essential components?

• An ecosystem is all biotic and abiotic things interacting within a area, including organisms, climate, soil, and water.

• An ecosystem is composed exclusively of autotrophic organisms that produce energy via photosynthesis.

• An ecosystem consists solely of abiotic factors such as water and soil that shape the landscape.

• An ecosystem is the habitat of a single organism and includes only its immediate surroundings.

Which of the following accurately distinguishes a population and a community within an ecosystem?

• A population refers to the physical environment; a community refers to the interactions between species.
• A population is a group of different species; a community is a single species.
• A population includes all species in an area; a community is just one species.
• A population is a group of individuals of the same species; a community is all living organisms in a area.

Which of the following best explains the dynamic relationship between biotic and abiotic factors in an ecosystem?

• Biotic factors function independently of abiotic conditions and are unaffected by environmental changes.

• Abiotic factors (ex:temperature) influence what living organisms can survive, which in turn can alter abiotic conditions through processes.

  (ex:erosion)

• Biotic factors do not interact with abiotic factors and exist in isolation from environmental conditions.

• Abiotic factors are influenced only by other abiotic factors and do not interact with living organisms.

What biome is colored?

• Temperate Grassland: moderate rainfall,fertile soils, & seasonal temperature variation.

• Desert: extremely low precipitation, little vegetation, & extreme temperature variations

• Savanna/Tropical Grassland: warm temperatures year-round, seasonal rainfall, and scattered trees.

• Temperate deciduous forest: four distinct seasons, broadleaf trees, & moderate precipitation.

Which biome is colored?

• Temperate deciduous forest : four distinct seasons, broadleaf trees, & moderate precipitation.

• Savanna/Tropical Grassland : dominated by grasses with occasional trees and seasonal rainfall.

• Desert: sparse vegetation, arid conditions, and extreme temperature ranges

• Tropical Rainforest: dense canopy/upper trees, high biodiversity, & consistent warm temperatures with heavy rainfall.

Which biome is colored?

• Desert: extremely low annual precipitation, sparse vegetation & extreme temperature variations

• Tropical Rainforest: consistently high temperatures, abundant rainfall, and high biodiversity.

• Tundra: permafrost, low-growing vegetation, and minimal precipitation

• Savanna/Tropical Grassland: seasonal rainfall, warm temperatures, & scattered trees among grasses.

What is a terrestrial biome?

• A terrestrial biome is determined exclusively by the mineral composition of its soil and underlying bedrock.

• A terrestrial biome is a land-based area that shares a combination of avg yearly temp. & precipitation (climate).

• A terrestrial biome is a subset of aquatic ecosystems that includes wetlands and estuaries.

• A terrestrial biome refers to any human-engineered landscape used for agricultural production.

What are the defining characteristics of a terrestial biome?

• Terrestrial biomes are primarily defined by their proximity to urban centers and human development.

• Terrestrial biomes are characterized by climate, vegetation, soil, and latitude which determines what living organisms could thrive in those environments.

• Aquatic biomes are defined solely by water temperature and salinity, with no influence from surrounding landforms.

• Terrestrial biomes are classified based on the presence of specific animal species and their migratory patterns.

What is a aquatic biome?

• An aquatic biome is limited to the deep ocean, where high pressure prevents sunlight from entering.

• An aquatic biome includes all biomes where photosynthesis occurs.

• An aquatic biome is a large & water dominated ecosystem, divided into freshwater and saltwater environments.

• An aquatic biome is a land-based ecosystem distinguished by annual rainfall and average temperatures

What are the defining characteristics of a aquatic biome?

• Aquatic biomes are defined by salinity, depth, temperature, and flow.

• Aquatic biomes are primarily influenced by atmospheric pressure and wind patterns.
• Aquatic biomes are defined by the presence of land and vegetation.
• Aquatic biomes are characterized by high altitudes and dry climates.
