GBH2425S1 Unit 3 Test - Ecology (Period 1)

Front

What are pioneer species?

Back

Species that are able to survive in hostile environments, usually autotrophs, and are the first to colonize areas, creating new ecological niches for other species.

Front

What is the difference between weather and climate?

Back

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

Front

What does a rapid growth population pyramid indicate?

Back

It indicates a population with a high birth rate and a larger proportion of young individuals, suggesting potential for significant population increase.

Front

What effect does a decrease in death rate have on a population?

Back

The population would increase due to more individuals surviving.

Front

What type of biome is characterized by trees that lose their leaves seasonally?

Back

Temperate deciduous forest.

Front

Define keystone species.

Back

A species that has a disproportionately large effect on its environment relative to its abundance, playing a critical role in maintaining the structure of an ecological community.

Front

What is a climax community?

Back

A stable and mature ecological community that has reached a steady state, where species composition remains relatively unchanged.

Front

What is the role of foundation species in an ecosystem?

Back

Foundation species are those that have a strong role in structuring a community, often providing habitat and resources for other species.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity enhances ecosystem productivity, stability, and resilience, allowing ecosystems to better withstand environmental changes.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food through photosynthesis or chemosynthesis, while heterotrophs consume other organisms for energy.
