Pre-AP Biology: Biomes & Levels of Ecology

Front

What is a biome?

Back

A biome is a large ecological area on the Earth's surface, with flora and fauna (plants and animals) adapting to their environment. Biomes are defined by factors such as climate, soil, and vegetation.

Front

What characterizes a rainforest biome?

Back

Rainforest biomes are characterized by high biodiversity, a warm climate, and high annual rainfall, typically exceeding 2000 mm (79 inches). They have a dense canopy of trees and a rich understory.

Front

What is the brackish water zone?

Back

The brackish water zone is the area where freshwater from rivers meets and mixes with saltwater from the ocean, creating a unique ecosystem that supports diverse species.

Front

What are the main characteristics of a desert biome?

Back

Desert biomes are characterized by low precipitation, extreme temperature fluctuations between day and night, and sparse vegetation, often consisting of drought-resistant plants.

Front

What defines a savanna biome?

Back

A savanna biome is characterized by seasonal droughts and fires, supporting a diversity of grasses and large herbivores, with scattered trees and shrubs.

Front

What is the tundra biome known for?

Back

The tundra biome is known for its cold climate, short growing seasons, and permafrost, which is permanently frozen ground. It has low biodiversity and is primarily covered with mosses, lichens, and low shrubs.

Front

How do climatographs represent biomes?

Back

Climatographs visually represent the average temperature and precipitation of a biome over a year, helping to illustrate the climate conditions that define different biomes.

Front

What is the significance of biodiversity in biomes?

Back

Biodiversity is crucial for ecosystem stability, resilience, and productivity. It allows ecosystems to adapt to changes and provides a variety of resources for humans.

Front

What adaptations do organisms in the desert biome have?

Back

Organisms in the desert biome have adaptations such as water conservation mechanisms, nocturnal behavior to avoid heat, and specialized structures to store water.

Front

What role do fires play in savanna ecosystems?

Back

Fires in savanna ecosystems help to maintain the grassland by preventing the encroachment of trees and shrubs, recycling nutrients, and promoting new growth.
