Front

What is the aphotic zone in an aquatic ecosystem?

Back

The aphotic zone is the layer of the water column where sunlight does not penetrate, preventing photosynthesis from occurring.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants and algae, provide most of the energy in ecosystems by converting sunlight into chemical energy through photosynthesis.

Front

Define an ecosystem.

Back

An ecosystem is a collection of living organisms (biotic factors) and nonliving things (abiotic factors) interacting in a specific area.

Front

Where are fish adapted to cool, dark waters typically found?

Back

Fish adapted to cool, dark waters are typically found in the profundal zone of lakes.

Front

What is the primary source of energy for almost all autotrophs?

Back

Almost all autotrophs get their energy from sunlight.

Front

What is the photic zone?

Back

The photic zone is the upper layer of a water body where sunlight penetrates, allowing photosynthesis to occur.

Front

What is the littoral zone?

Back

The littoral zone is the nearshore area of a water body where sunlight reaches the bottom, supporting diverse plant and animal life.

Front

What are carnivores?

Back

Carnivores are organisms that primarily eat other animals for energy.

Front

What is a community in ecological terms?

Back

A community is a group of different species living together in a specific area, interacting with one another.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are the living components of an ecosystem, while abiotic factors are the nonliving physical and chemical elements.
