Aquatic Ecosystem Flashcard

Front

What role do microorganisms play in aquatic ecosystems?

Back

Microorganisms contribute to nutrient cycling by breaking down organic matter.

Front

How are the headwaters of a river characterized?

Back

Headwaters are characterized by cold, fast-flowing water with high levels of dissolved oxygen.

Front

What defines mangrove swamps?

Back

Mangrove swamps are characterized by salt-tolerant trees and shrubs known as mangroves.

Front

What does the term 'oligotrophic' mean in the context of aquatic ecosystems?

Back

Oligotrophic refers to ecosystems with low nutrient levels and low algal growth.

Front

What percentage of the Earth's water resources is freshwater?

Back

The remaining 3.5% of the Earth's water resources is freshwater.

Front

What is the significance of dissolved oxygen in aquatic ecosystems?

Back

Dissolved oxygen is crucial for the survival of aquatic organisms, particularly fish and invertebrates.

Front

What are the primary producers in aquatic ecosystems?

Back

Primary producers in aquatic ecosystems include phytoplankton, algae, and aquatic plants.

Front

How do estuaries contribute to biodiversity?

Back

Estuaries provide a unique habitat that supports a diverse range of species, both aquatic and terrestrial.

Front

What is the impact of nutrient pollution on aquatic ecosystems?

Back

Nutrient pollution can lead to algal blooms, which deplete oxygen and harm aquatic life.

Front

What adaptations do organisms in mangrove swamps have?

Back

Organisms in mangrove swamps have adaptations such as salt filtration and specialized root systems.
