Chapter 6 Review (Biomes + Aquatic Ecosystems)

What is gross primary productivity?

• The total amount of energy captured by photosynthesis in an ecosystem.

• The total amount of energy consumed by herbivores in an ecosystem.

• The total amount of energy lost as heat in an ecosystem.

• The total amount of energy produced by decomposers in an ecosystem.

What is a swamp?

• A dry area with little vegetation.

• A wetland dominated by woody plants, such as trees and shrubs, and often flooded.

• A type of desert ecosystem with cacti.

• A body of water that is always frozen.

What is the role of primary producers in an ecosystem?

• They convert sunlight into energy through photosynthesis, forming the base of the food chain.

• They decompose organic matter and recycle nutrients back into the soil.

• They consume primary producers and transfer energy to higher trophic levels.

• They regulate the population of herbivores in the ecosystem.

What is a savanna?

• A biome characterized by dense forests and high rainfall.

• A biome characterized by grasslands with scattered trees, found in regions with a seasonal rainfall pattern.

• A type of desert with minimal vegetation and extreme temperatures.

• A coastal region with sandy beaches and tropical climate.

What is the importance of biodiversity in ecosystems?

• Biodiversity is essential for aesthetic beauty and tourism.

• Biodiversity contributes to ecosystem resilience, productivity, and the ability to adapt to changes.

• Biodiversity has no significant impact on ecosystems.

• Biodiversity only benefits certain species and not the ecosystem as a whole.

What are the characteristics of a taiga biome?

• It is characterized by tropical rainforests and warm temperatures.

• It is characterized by coniferous forests, cold temperatures, and long winters.

• It is characterized by deserts and high temperatures.

• It is characterized by grasslands and moderate rainfall.

What defines a marsh?

• A marsh is a dry area with no vegetation.

• A marsh is a wetland area dominated by herbaceous plants, particularly reed grasses, and characterized by standing water.

• A marsh is a forested area with tall trees and dense foliage.

• A marsh is a rocky terrain with minimal water presence.

What is a tropical rain forest?

• A biome characterized by high rainfall, high humidity, and a diverse range of plant and animal species.

• A dry area with little vegetation and low rainfall.

• A cold region with permanent ice and snow.

• A grassland with scattered trees and seasonal rainfall.

What does 'deciduous' mean?

• Trees or plants that shed their leaves annually.

• Trees that remain green all year round.

• Plants that grow in water.

• Trees that produce fruit only in summer.

What is an estuary?

• An estuary is a coastal area where freshwater from rivers meets and mixes with saltwater from the ocean.

• An estuary is a type of freshwater lake that is isolated from the ocean.

• An estuary is a region of land that is permanently flooded with saltwater.

• An estuary is a coastal area that is only inhabited by marine life.
