Front

What is uniform dispersion?

Back

A pattern of spacing in which individuals are evenly distributed in an area, often due to territorial behavior or resource availability.

Front

What biome is characterized by a layer of permafrost?

Back

Tundra, a cold biome where the ground is permanently frozen beneath the surface.

Front

What defines a desert biome?

Back

An area where rainfall is less than 50 centimeters per year, resulting in arid conditions.

Front

What is the ultimate source of energy in an ecosystem?

Back

Sunlight, which is harnessed by plants through photosynthesis.

Front

What is a deciduous forest?

Back

A forest that contains trees that shed their leaves during a specific season, typically in autumn.

Front

What is clumped dispersion?

Back

A pattern of spacing where individuals are grouped together in patches, often due to resource availability or social behavior.

Front

What is random dispersion?

Back

A pattern of spacing where individuals are distributed unpredictably, without a clear pattern.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is a biome?

Back

A large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What is the difference between a grassland and a tundra?

Back

Grasslands are characterized by open areas dominated by grasses, while tundras are cold regions with permafrost and limited vegetation.
