There are two main types of water biomes: freshwater and saltwater. Freshwater biomes include rivers, streams, lakes, and ponds, and have low salt levels. Saltwater biomes like oceans have high salt levels and can be divided into photic and aphotic zones. Estuaries where freshwater meets saltwater are especially nutrient-rich. Aquatic organisms in all water biomes are limited by factors like salt levels, oxygen, and sunlight availability.

The aquatic biome covers nearly 75% of the Earth's surface and can be divided into fresh water and marine water regions. Fresh water regions have low salt concentrations, while marine water regions make up the largest biome. Aquatic biomes include ponds, lakes, streams, rivers, wetlands, oceans, coral reefs, and estuaries. These contain zones like littoral, limnetic, profundal, and benthic that each support different types of plants and animals.
FRESH WATER BIOME
The document is a presentation about freshwater biomes by Kisesa Hamisi from Tanzania. It discusses the key characteristics of freshwater biomes including temperature, soil types, locations in areas with high nutrition, and morphological appearances of bodies of water. It also outlines the major threats as pollution and global warming. Additionally, it describes the major types of freshwater biomes such as wetlands, rivers and streams, and lakes and ponds. Finally, it proposes ways to protect freshwater biomes such as using less water and engaging in recycling.
Fresh water ecosystems
This document summarizes different types of freshwater ecosystems. It discusses lakes, ponds, wetlands, and rivers. Lakes and ponds can form naturally or be created by humans for uses like power generation and recreation. Wetlands are areas covered by fresh water and include marshes with non-woody plants and swamps dominated by woody plants. Wetlands provide benefits like filtering pollution and reducing floods. Rivers originate from snow melt and change as they flow from mountains, becoming warmer and slower.
Fresh water ecosystem
Fresh Water & Marine Ecosystems document describes various aquatic ecosystems. It discusses freshwater ecosystems including lakes, rivers, ponds, and flooded plains. It describes the characteristics and flora and fauna of these systems. Lotic ecosystems with fast moving water like rivers are described as well as lentic still water ecosystems. Marine ecosystems like estuaries, mangroves, and coral reefs are also overviewed. The document concludes with a section on salt pans, which are flat areas where salt accumulates through evaporation of water in desert climates.
Freshwater biomes
Freshwater biomes can be characterized by their salt concentration, links to surrounding terrestrial environments, and water flow patterns. Lakes and ponds are bodies of standing freshwater that can be classified as oligotrophic, mesotrophic, or eutrophic depending on their nutrient levels. Rivers and streams transport water from headwaters to mouths, with zones that change from clear and rocky to wider and silty based on elevation and sediment load. Wetlands are rich freshwater habitats that support hydrophytic plants like marshes, swamps, and bogs.
Life in water
The document discusses various aspects of life in water. It begins by providing statistics on the percentage of Earth covered by water and where that water is located. It then describes key concepts like the hydrologic cycle and factors that influence aquatic environments like light, temperature, water movement, salinity, and oxygen levels. Specific habitats are examined in more detail, including oceans, coral reefs, kelp forests, intertidal zones, estuaries, salt marshes, and mangrove forests. The organisms and environmental conditions of each are summarized.
Economic benifits of estuary system
Estuaries provide economic benefits through tourism, the food industry, and protection of infrastructure. They support fisheries and commercial activities that supply natural resources for tourism destinations like the Puerto Princesa Underground River. Products from estuaries like scallops, clams, oysters, and mussels are a major contributor to the aquatic industry. Estuaries also protect coastal areas and support important public infrastructure by serving as harbors and ports vital for shipping, transportation, and industry.
Estuaries
1. An estuary is a partially enclosed coastal body of water where freshwater from rivers and streams mixes with saltwater from the ocean.
2. Estuaries contain many habitat types, including marshes, mangroves, beaches, and seagrasses, and provide nurseries for many marine species.
3. They are economically and ecologically important, providing habitats for wildlife, fisheries resources, filtration of pollutants, and protection from floods and storms.

Aquatic Ecosystems
Aquatic ecosystems include freshwater and saltwater environments. Freshwater ecosystems like lakes and ponds contain plants, algae, and animals like fish, frogs, and birds. Oceans are large saltwater bodies that contain diverse ecosystems from shallow to deep waters and a variety of sea life. Estuaries are areas where freshwater from rivers meets saltwater from the ocean, exposing plants and animals to changing salt concentrations with the tides. Salt marshes are flat lands overflowed by saltwater like Masonboro Island in North Carolina.
Estuary Presentation
The document summarizes key aspects of estuaries, including their global distribution, types, biodiversity, and human impacts. Estuaries are found where rivers meet oceans, with notable examples including Chesapeake Bay and the Amazon River. They contain salt marshes or mangroves and experience fluctuating salinity levels from tides, seasons, and rainfall. Estuaries support abundant life and are heavily populated areas, but have been degraded by industrialization through dumping, development, and destruction of habitats.
Our estuaries
Northland's estuaries provide rich, productive environments. They are formed where freshwater rivers meet saltwater seas, creating areas where fresh and salt water mix. Estuaries support many interconnected plants and animals, and were important places for early Māori and European settlement. However, estuaries now face threats from pollution, development, and invasive species. The Northland Regional Council works to sustainably manage these fragile ecosystems.

Lake
This document discusses stratification in lakes. It describes how lakes are vertically divided into three layers - the epilimnion on top which is mixed by wind, the metalimnion in the middle where temperature drops rapidly, and the hypolimnion on the bottom which remains cool and unaffected by wind. It also explains how the stability of this stratification depends on the energy required to uniformly mix the layers, and discusses differences between eutrophic and oligotrophic lakes in terms of biomass, diversity, and water quality.
Estuaries
Estuaries are areas where freshwater and seawater mix, found around the world. They contain aquatic plants like sea lavender and seagrass, and house many animals such as mussels, shrimp, worms and birds. Estuaries were once destroyed by human development but are now recognized as valuable ecosystems that help fish populations and ocean water quality.
Ecosystem Based Management of Reservoirs
IWMI representative gave this presentation on what ecosystem based management of reservoirs is and how to carry it out.
Aquatic environment
An aquatic ecosystem is a community of organisms that live in bodies of water. There are two main types: marine ecosystems, which cover most of the Earth's surface, and freshwater ecosystems, which include lakes, rivers, and wetlands. Freshwater ecosystems can be lentic (still water) or lotic (flowing water). Lentic systems have littoral, photic, and aphotic zones, while lotic systems have zones determined by flow speed. Water pollution is a major threat and can kill organisms by reducing oxygen or increasing nutrients.
Term 2 Geography Project
There are several strategies for river channel management including river channelization, river re-sectioning, vegetation planting and clearance, and bank protection. River channelization involves altering the river channel to increase water flow and prevent flooding by clearing obstacles and dredging. River re-sectioning straightens river meanders through cut-offs to shorten and increase water flow. Vegetation planting stabilizes banks but slows water flow while vegetation clearance improves flow but can damage banks. Bank protection uses structures like levees and dykes to prevent erosion during high water volumes.

This document provides an overview of freshwater ecosystems, including types, characteristics, and flora and fauna. It discusses the two main types of freshwater ecosystems: lentic systems, which include ponds and lakes, and lotic systems, which include streams and rivers. For ponds and lakes, it outlines the different zones from littoral to profundal and describes characteristics like temperature variation. It also discusses general characteristics of streams and rivers like temperature differences between headwaters and mouths. Finally, it provides some examples of common plant and animal life found in freshwater ecosystems.
Classification of lakes
Lakes are helpful in controlling weather and local climate. Lakes are helpful for creating irrigation facilities and recreation. In some places, lakes are good sources for water supply for drinking. Every lake, is unique in terms of its size, morphometry, water availability, water chemistry, physics, hydrology and biology. There are several type, kinds and categories of lakes in the world.
Kolleru lake aquaculture
Kolleru Lake is one of Asia's largest freshwater lakes located in Andhra Pradesh, India. It serves as an important habitat for many resident and migratory birds. Aquaculture became popular in the 1970s when the government encouraged fishermen to form cooperatives and convert land to fish ponds and tanks. However, over time the extensive aquaculture practices polluted the lake water and caused salinity issues by pumping out saline water. As a result, the lake has been depleted and thousands of local people now lack access to clean drinking water. While courts have ordered the demolition of illegal fish tanks and restoration efforts, more needs to be done to properly conserve this important wetland ecosystem.
Freshwater ecosystem (2)
Freshwater ecosystems include lakes, ponds, rivers, streams, springs, and wetlands. There are two main types - lentic ecosystems, which are standing bodies of water, and lotic ecosystems, which are running water. Lentic ecosystems can be further divided into zones based on depth and vegetation. Lotic ecosystems have rapid zones with strong currents and pool zones with slower currents. Wetlands are areas that are periodically saturated or flooded with shallow water and support unique plant and animal communities. Forested wetlands include swamps and floodplain forests while tidal freshwater marshes occur along estuaries. Freshwater ecosystems provide important resources but occupy a small area globally.
Estuaries and barrier islands
Estuaries are coastal bodies of water where fresh river water and salty ocean water mix, creating a unique environment. They are highly productive ecosystems that provide important habitat for many species and offer economic benefits to humans through activities like tourism, fishing, and shipping. Barrier islands help protect estuaries by forming a barrier against ocean waves and tides. Both estuaries and barrier islands are delicate systems vulnerable to threats from rising sea levels, erosion, and storms.

Aquatic biome
The aquatic biome includes freshwater and marine ecosystems. Freshwater ecosystems include lakes, ponds, rivers, and streams, which can be divided into lentic (calm water) and lotic (running water) systems. Marine ecosystems cover the vast oceans and include pelagic, benthic, abyssal, and intertidal zones. Key aquatic habitats include coral reefs, which support high biodiversity, estuaries where freshwater mixes with saltwater, and wetlands that provide habitat for many species. Aquatic ecosystems contain diverse communities of plankton, nekton that actively swim, and benthos attached to surfaces.
Marine Biomes
Marine biomes make up the largest percentage of aquatic biomes on Earth and involve a medium to high percentage of salt in the water. They include oceans, coral reefs, and estuaries. Coral reefs are usually found in shallow, warm waters and are important for controlling carbon dioxide levels and protecting coasts from strong currents. Estuaries involve both freshwater and salt water, protecting water quality while serving as centers of coastal communities. Marine biomes contribute substantially to global oxygen production and carbon dioxide absorption.

Estuaries: Introduction
This document discusses estuaries, including their physical characteristics and ecosystems. Estuaries are bodies of water where freshwater rivers meet and mix with saltwater oceans. They can have varying salinity levels depending on their location and tidal influences. Estuaries provide important habitat for many species but are also impacted by human activities like pollution. Organisms living in estuaries have developed ways of coping with the ever-changing conditions, such as maintaining constant internal salt levels or burrowing in the mud.
Freshwater ecosystems
Freshwater ecosystems include streams, rivers, ponds, lakes, and wetlands. Streams join to form larger rivers. Ponds and lakes have three zones - a littoral zone near shore with plants, an open-water zone where sunlight reaches, and a deep-water zone without sunlight. Wetlands soak up flood waters and replenish groundwater. They include marshes with grasses and swamps with trees. Over time, a lake can fill in with sediment and transform into a forest. The ocean contains diverse ecosystems shaped by temperature, depth, and sunlight. It has zones like intertidal, neritic, oceanic, and benthic that support different life.
Marine and coastal ecosystems
Marine and coastal ecosystems are diverse and complex systems. The marine ecosystem is the largest ecosystem on Earth, covering over 70% of the planet's surface. It contains a variety of habitat types, from coral reefs and kelp forests to deep sea and open ocean environments. Coastal ecosystems like mangroves, sandy shores, and estuaries exist at the interface between land and sea. These ecosystems support a high level of biodiversity but are threatened by rising sea levels and ocean acidification due to climate change. Careful management is needed to protect these important ecosystems.
Aquatic ecosystems revised
There are several key factors that determine the types of organisms found in aquatic ecosystems, including dissolved oxygen levels and water temperature. Organisms are adapted to the conditions in different freshwater and marine ecosystems, such as streams, rivers, lakes, ponds, wetlands, estuaries, and open ocean. Marine ecosystems can be divided based on depth, light availability, and location into intertidal zones, coastal oceans, open oceans, and benthic zones, each with distinctive characteristics and organisms.

The document describes several types of freshwater and marine ecosystems. It discusses streams and rivers, ponds and lakes, wetlands including marshes, swamps, and bogs. It also covers estuaries, coral reefs, kelp forests, hydrothermal vents, and the zonation of marine ecosystems from the intertidal zone to the open ocean and benthic zones. Key details are provided on the defining characteristics, locations, and common organisms found in each ecosystem.
Ecology Chapter 25: AQUATIC ENVIRONMENT
The document discusses various aquatic ecosystems including lakes, rivers, estuaries, and oceans. It describes the key physical characteristics and biological adaptations that allow organisms to thrive in different aquatic environments. Lakes can be formed through geological or non-geological processes. Aquatic life is richest in shallow waters near shorelines. Rivers flow into seas forming estuaries with mixing of freshwater and saltwater. Oceans have vast benthic communities on the seafloor and unique hydrothermal vent and coral reef ecosystems. Primary productivity in aquatic environments is governed by light and nutrient availability.
Marine ecosystem
The document summarizes several marine ecosystems. It describes how oceans cover 70% of the Earth's surface and include shorelines like tidal flats and mangrove forests. Specific ecosystems are found around the world, depending on climate and geography. These include coral reefs, estuaries, salt marshes, mangrove forests, and the deep sea. Salt marshes are coastal wetlands flooded by tides that are dominated by salt-tolerant grasses. The intertidal zone is the shore area above and below the water line during tides, containing habitats for starfish and coral. Mangroves are salt-tolerant trees adapted to harsh coastal conditions.
Lake ecology 2017
Limnology is the study of inland aquatic ecosystems. The document defines different types of freshwater environments like lakes, ponds, rivers, swamps, and marshes. It describes the characteristics of these environments and explains concepts in lake ecology like littoral, limnetic, profundal, and benthic zones. Key factors that influence lakes include light, temperature, nutrients, and stratification into epilimnion, metalimnion, and hypolimnion layers.
Estuarine systems
The Estuarine System consists of deepwater tidal habitats and adjacent tidal wetlands that are usually semienclosed by land but have open, partly obstructed, or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Offshore areas with typical estuarine plants and animals, such as red mangroves (Rhizophora mangle) and eastern oysters (Crassostrea virginica), are also included in the Estuarine System.

How to use a dichotomous key (2) (5)
This document provides instructions on how to use a dichotomous key to identify eight species of Norns, which are divided based on physical characteristics such as ear shape, tail presence, waving behavior, and hair. The key guides the user through a series of two-choice decisions to determine the correct scientific name of each Norn species.
Cells are cool ppt.
All living things are composed of cells, either as single-celled (unicellular) or multi-celled (multicellular) organisms. The human body contains many cell types that work together to form tissues, organs, and body systems. For example, bone cells form bone tissue which makes up the skeletal system, muscle cells form muscle tissue to create the muscular system, and nerve cells form nerve tissue that comprises the nervous system. Ultimately, cells are the basic unit of structure and function that allows the human body to work as an integrated whole.
Diffusion (2)
This document discusses different types of transport - diffusion, osmosis, and active transport. It provides examples of CO2, water, food, and oxygen moving between areas of higher and lower concentration. It indicates whether each example represents diffusion, osmosis, or active transport. For the example of a cell in a salt water solution, it states that osmosis would cause water to move out of the cell since there is more water inside the cell than outside in the salt solution.
Looking inside cells notes (1)
This document summarizes the structures and functions of organelles found within cells. It explains that organelles such as the cell membrane, cell wall, mitochondria, vacuoles, lysosomes, chloroplasts, endoplasmic reticulum, ribosomes, Golgi bodies, and nucleus carry out specific functions to keep the cell alive. While plant and animal cells contain these organelles, bacterial cells are smaller and lack a nucleus.
Interactions (2)
This document discusses interactions between organisms and their environments. It describes three main types of interactions: competition, where organisms compete for limited resources; predation, where one organism hunts another for food; and symbiosis, a close relationship where at least one organism benefits. Symbiosis includes mutualism, where both benefit; commensalism, where one benefits and the other is unaffected; and parasitism, where one benefits and the other is harmed. Examples of each interaction type are provided.
Energy flow
This document discusses ecosystems and energy flow between organisms. It begins by defining producers (autotrophs) which get energy from the sun through photosynthesis. Consumers (heterotrophs) depend on producers for nutrients and include herbivores, carnivores, scavengers, and decomposers. Energy and matter are transferred between trophic levels in food chains and food webs. Ecological pyramids illustrate how biomass, numbers, and energy decrease at higher trophic levels due to energy lost as heat. Cycles of water, carbon, nitrogen, and phosphorus allow these essential elements to be reused in ecosystems.

Water Biomes
- 1. Water Biomes
- 2. Water Biomes The limiting factors in water biomes are: – Amount of salt (salinity) – Amount of dissolved oxygen – Sunlight
- 3. 2 Types of Water Biomes • Freshwater – Rivers and Streams – Lakes and Ponds • Saltwater – Ocean – Estuaries – Seashores (tidal areas)
- 4. Freshwater Biomes Freshwater contains little or no salt, so it has a LOW salinity. Flowing freshwater = rivers and streams Still Freshwater = lakes and ponds
- 5. Flowing Freshwater • Streams – The faster a stream flows the greater the amount of dissolved oxygen in it. Faster water flows = oxygen
- 6. Flowing Freshwater • Streams – The fish that live in streams are adapted to fast moving water
- 7. Flowing Freshwater • Rivers – Water moves slower in a river and debris settles on the bottom. – Because of this, rivers tend to have more nutrients and less dissolved oxygen. nutrients and oxygen
- 9. Freshwater • Ponds – Small, shallow bodies of water – Sunlight penetrates all the way to the bottom – Most completely filled with plant material – Very high amount of nutrients
- 11. Freshwater • Lakes – Larger and deeper than ponds – Plant growth is limited to the shoreline – Sunlight does NOT penetrate to the bottom= no plants after a certain depth!
- 13. Water Biomes Plankton are microscopic algae, plants, and other organisms that float on the surface of water biomes. They need sunlight to survive.
- 14. Water Biomes Phytoplankton are important producers in water biomes. They are the first step in many aquatic food chains
- 15. Saltwater Biomes About 95% of the water on Earth has a high concentration of salt. (High salinity)
- 16. Saltwater • Estuaries (Wetlands) – Area where a river meets an ocean – Mix of salt and freshwater – Located near coastlines, border land – Extremely fertile – Nutrient levels are higher than both salt and freshwater
- 18. Saltwater • Seashores – Tides have a huge influence on life here – INTERTIDAL ZONE- portion of the shoreline that is covered with water at high tide and exposed to the air at low tide.
- 19. Intertidal Zone • Can be sandy or rocky • Small fish, clams, crabs, other mussels are trapped in the TIDAL POOLS during low tide
- 20. Intertidal Zone
- 21. Saltwater • Oceans – Can be divided into 2 main life zones 1. Photic zone- sunlight penetrates 2. Aphotic zone- NO sunlight
- 23. Photic Zone- above 200m • Made up of the euphotic & disphotic zones • Sunlight penetrates • Plant life and animal life is abundant
- 24. Aphotic Zone- below 200m • Sunlight DOES NOT penetrate • There are no plants • Animal life is highly specialized
- 25. Aphotic Zone- below 200m • Many of the denizens of the deep ocean have a special adaptation known as bioluminescence
