Ch. 6 Biomes Test

Front

What is a biome?

Back

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

Front

What factors influence the characteristics of a biome?

Back

Climate, soil type, and the availability of water are key factors that influence the characteristics of a biome.

Front

What is net primary production (NPP)?

Back

Net primary production is the net amount of organic matter that an ecosystem or biome produces after accounting for the energy used by producers for respiration.

Front

Which biomes typically have the highest net primary production?

Back

Tropical rainforests and wetlands typically have the highest net primary production due to their warm temperatures and abundant moisture.

Front

What is the difference between gross primary production (GPP) and net primary production (NPP)?

Back

Gross primary production is the total amount of organic matter produced by photosynthesis, while net primary production is the amount remaining after subtracting the energy used for respiration.

Front

What is a canopy in a rainforest?

Back

The canopy is the upper layer of a rainforest formed by the tops of tall trees, creating a dense cover that blocks sunlight from reaching the layers below.

Front

What role do decomposers play in a biome?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and supporting plant growth.

Front

How does climate differ from weather?

Back

Climate refers to the long-term average of weather conditions in a specific area, while weather describes short-term atmospheric conditions.

Front

What is the emergent layer in a rainforest?

Back

The emergent layer is the highest layer of the rainforest, where a few trees extend above the canopy, receiving the most sunlight and experiencing strong winds.

Front

What are epiphytes?

Back

Epiphytes are plants that grow on other plants (usually trees) for support, but do not harm them, often found in tropical rainforests.
