Front

What biome is characterized by high temperatures and very low precipitation according to a Whittaker climograph?

Back

Front

What principle states that no two species can occupy exactly the same niche in exactly the same habitat at the same time?

Back

Competitive Exclusion Principle

Front

What type of organisms are heterotrophs that are involved in external digestion?

Back

Saprotrophs

Front

Define anaerobic respiration.

Back

A type of respiration that occurs without oxygen, often resulting in the production of energy through fermentation.

Front

What is the role of abiotic factors in an ecosystem?

Back

Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.

Front

Explain the significance of the competitive exclusion principle in ecology.

Back

It explains how species coexistence is limited and how competition for resources can lead to the exclusion of one species.

Front

What are saprotrophs and their ecological role?

Back

Saprotrophs are organisms that decompose organic matter, recycling nutrients back into the ecosystem.

Front

List three examples of abiotic factors in an ecosystem.

Back

Sunlight, temperature, and water.
