Ecology Test Review

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen, which can harm aquatic life.

Front

What directly causes the death of fish in eutrophication?

Back

Bacteria use up oxygen in respiration.

Front

What abiotic factor most likely influenced the evolution of desert plants?

Back

The desert's dry environment.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of species on Earth.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What happens to the ecosystem if there is a sudden increase in the cricket population?

Back

There would be a decrease in the grass/flowers population.

Front

What is an example of an abiotic factor?

Back

Abiotic factors include non-living components like temperature, water, and soil.

Front

How do bacteria contribute to eutrophication?

Back

Bacteria decompose organic matter, consuming oxygen in the process, which can lead to hypoxic conditions harmful to fish.

Front

What is the significance of the desert's high day temperatures for plant adaptation?

Back

High day temperatures can lead to adaptations such as water conservation mechanisms in desert plants.

Front

What role does oxygen play in aquatic ecosystems?

Back

Oxygen is essential for the survival of fish and other aquatic organisms; its depletion can lead to fish kills.
