Some factors that describe aquatic ecosystems include:
- Water temperature: The temperature of the water can vary and influence the type and abundance of organisms that can survive in different aquatic ecosystems.
- Salinity: The level of salt in the water, ranging from freshwater to brackish water to saltwater, can greatly impact the kind of organisms that can survive in a particular ecosystem.
- Water depth: The depth of water can determine the availability of sunlight, dissolved oxygen, and nutrients, which affect the distribution and abundance of aquatic organisms.
- Water flow: The velocity of the water, whether it is still or flowing, can shape the physical structure and patterns of biological communities in aquatic ecosystems.
- Nutrient availability: The amount and type of nutrients present in the water, such as nitrogen and phosphorus, influence the growth of plants and algae and consequently the composition of the food web in aquatic ecosystems.
- Oxygen levels: The concentration of dissolved oxygen in the water is crucial for the survival of aquatic organisms, as it is necessary for respiration, and therefore, it impacts the distribution and behavior of species.
- Light availability: The amount and quality of sunlight that penetrates the water determine the depth at which photosynthesis can occur, affecting the growth and distribution of plants and algae, as well as the behavior of other organisms.
- Substrate composition: The physical characteristics of the bottom surface, such as the presence of sand, rocks, or mud, influence the structure and diversity of benthic communities in aquatic ecosystems.
- Human impact: Human activities, including pollution, habitat destruction, overfishing, and introduction of invasive species, can have significant impacts on the health and functioning of aquatic ecosystems.
