Block 3 Water in the Ecosystems
There are two main types of aquatic ecosystems: freshwater and saltwater. Freshwater ecosystems include lakes, rivers, and wetlands, and are characterized by factors like light, dissolved gases, and temperature. Saltwater or marine ecosystems make up the oceans and coastal waters, and are regulated by light, salt levels, temperature, and currents. They contain a diversity of life including phytoplankton, invertebrates like jellyfish and coral, and vertebrates like fish and marine mammals. Estuaries are transitional ecosystems where freshwater mixes with saltwater from the ocean.
Coral reef presentation
Coral reefs are diverse ecosystems home to about 25% of marine life. They are made up of plants, fish, and animals living together. Some threats to coral reefs are destructive fishing practices like cyanide and dynamite fishing as well as industrial waste and oil dumping polluting the oceans. Coral reefs are important habitats supporting many species, and cover 25% of the sea bed.
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.
Intertidal powerpoint (compatibility copy)
The document describes the intertidal zone, where land meets the sea and is alternately submerged and exposed by tides. It is divided into four zones based on tidal exposure: the splash zone, high tide zone, middle tide zone, and low tide zone. Organisms in each zone have adapted to the varying temperatures, salinity, moisture, and sunlight exposure caused by the daily tides. Competition for space is also a major biological factor, as more zones have longer submergence times with greater resources.

Five classification of an estuarine ecosystem
This document outlines 5 classifications of estuarine ecosystems according to Howard T. Odum:
1. Physically stressed systems that experience high energy waves, currents, temperature/salinity fluctuations or sedimentation. These systems have low diversity but include rocky shores, tidal channels, and man-made canals.
2. Arctic ecosystems with ice stress, including glacial fjords and winter ice zones, which experience light, temperature, and ice limitations.
3. Temperate coastal ecosystems with seasonal programming, like drowned river valleys and embayments, that experience seasonal pulses in productivity and reproduction.
4. Tropical coastal ecosystems of high diversity that experience low physical stresses, allowing greater diversity,
Estuary Notes
Estuaries are semi-enclosed areas where fresh water and seawater meet and mix, forming one of the most productive environments on earth. They serve as protected habitat and vital breeding and feeding grounds for many species. Cities were often built near estuaries due to the abundance of seafood. There are four main types of estuaries that form from different geological processes: drowned river valleys, bar-built, tectonic, and fjords. Estuaries have varying salinity levels and substrates that influence the distribution of species and ecological processes within them.
Coral reefs
Coral reefs are underwater structures made of calcium carbonate secreted by coral polyps, which are tiny colonial animals found in nutrient-poor marine waters. Coral reefs provide a diverse ecosystem and home to 25% of marine species despite occupying less than 0.1% of the ocean. Coral reefs are fragile due to their sensitivity to water temperature and are threatened by climate change, ocean acidification, overfishing, pollution, and algal growth caused by runoff.
Sea level rise on estuarine slopes, sediment particle size and wave exposure ...
This document discusses how physical factors like sea level rise, sediment particle size, beach slope, and wave exposure affect benthic invertebrate assemblages in estuaries. It finds that the abundance, biomass, and oxygen consumption of intertidal macrofauna and meiofauna are significantly impacted by interactions among these physical factors. Specifically, mud flats have lower wave exposure and finer sediments leading to higher macrofauna biomass, while sandy shores have higher wave exposure and coarser sediments resulting in lower biomass. Sea level rise is expected to make estuaries less diverse and productive by reducing these metrics.
Characteristics of an estuary

The document concludes by covering Oregon's native and introduced fish species, noting over 90 species including salmon, trout, suckers and introducing threats from invasive species.
Estuaries
Estuaries are productive ecosystems where rivers meet the ocean, supporting abundant plant and animal life. They are transitional zones with both freshwater and saltwater. Over time, sediments can accumulate and block estuaries, turning them dry if not managed. Estuaries are economically and ecologically important for humans, providing habitat for fisheries, recreation, and coastal development. However, they are threatened by overfishing and pollution.
Intertidal Zones
The intertidal zone is the area between high and low tide that is alternately covered and exposed by the rising and falling of ocean tides. Organisms living in the intertidal zone must be adapted to frequent changes in temperature, salinity, and water movement as the tides come in and out. They face challenges of living in a habitat that fluctuates between aquatic and terrestrial conditions on a daily basis.
Ocean ecosystem

What are the Biotic and Abiotic Conditons in estuaries and intertidal zones
The document summarizes biotic and abiotic conditions in intertidal zones and estuaries. The intertidal zone is the area between the highest and lowest tide marks that is alternately covered and exposed by tides. It contains rocky shores, sand, or mudflats and is inhabited by organisms adapted to periodic submergence and exposure, such as sea stars, crabs, and shellfish. Estuaries are areas where freshwater from rivers meets saltwater from the sea, creating a brackish environment with lower salinity than the ocean due to freshwater dilution.
Ocean ecosystem summative
The document discusses the ocean ecosystem located off the coast of Surabaya, Indonesia near Kenjeran Beach. It notes that 80% of life is found in the ocean and describes some of the biotic and abiotic components as well as the interdependencies between living and non-living things. However, the ocean is facing problems of pollution from rubbish, oil spills, and overfishing which are negatively impacting populations. Potential actions are suggested such as reducing plastic use, waste, and consumption of seafood to help protect ocean life and coral reefs.
Developing environmentally sustainable societies
“Something will have gone out of us as a people if we ever let the remaining wilderness be destroyed; if we permit the last virgin forests to be turned into comic books and plastic cigarette cases; if we drive the few remaining members of the wild species into zoos or to extinction; if we pollute the last clear air and dirty the last clean streams and push our paved roads through the last of the silence, so that never again will Americans be free in their own country from the noise, the exhausts, the stinks of human and automotive waste.” ~Wallace Stegner, letter to David E. Pesonen of the Wildland Research Center, 3 December 1960 (Thanks, Bekah)

Over time, estuaries fill with sediment from rivers and tides, eventually transforming into dry land. They provide food and shelter for many species of fish, birds, shellfish, and mammals.
Ben's coral reef
Coral reefs are the most diverse marine habitats, formed through the slow growth of corals and their symbiotic relationship with algae. Framework builders like corals and algae precipitate calcium carbonate to slowly build the reef structure upward over time. This creates a topographically complex environment that is home to thousands of fish and invertebrate species. However, coral reefs are threatened by overfishing, careless tourism, pollution, and other human impacts that can damage their delicate ecosystems.
Coral reefs

Coral Reefs
Coral reefs are ecosystems located in warm, shallow ocean waters that are home to many species. They are made up of coral polyps that secrete calcium carbonate to form hard structures. Coral reefs come in several types - fringing reefs lie adjacent to shores, barrier reefs lie further offshore, and atolls form from sunken barrier reefs, enclosing lagoons. Coral reefs support a diversity of life through symbiotic relationships and provide important benefits to coastlines and economies. However, they are threatened by human activities such as pollution, overfishing, and coastal development.
Oceans 05 ocean interactions
Coral reefs support diverse ecosystems and have a symbiotic relationship with Earth's spheres. They help the biosphere by providing habitat, the hydrosphere by filtering water, the geosphere by protecting coastlines from erosion, and the atmosphere by producing oxygen through photosynthesis. However, coral reefs are threatened by global warming, pollution, and tourism. Protecting coral reefs is important for maintaining balance within Earth's interconnected systems.

Marine Ecology Notes.ppt
The document summarizes key aspects of the marine environment, including the following:
- The ocean covers 71% of the Earth's surface and supports over 250,000 known marine species. It plays a crucial role in regulating the planet's climate and carbon levels.
- There are two major zones - coastal and open ocean. Coastal zones include estuaries, shorelines, coral reefs, and kelp forests, which provide diverse habitats. The open ocean has zones from surface waters to the deep sea floor.
- Human activities like pollution, overfishing, and climate change threaten marine life. While the oceans can dilute some pollution, dumping of hazardous waste risks further degradation of these vital ecosystems.
Freshwater
Freshwater ecosystems include lakes, ponds, rivers and streams. Lakes are large bodies of freshwater surrounded by land, while ponds are smaller. Lake Baikal contains about one fifth of the world's freshwater. Rivers and streams are moving bodies of freshwater that originate in mountains and flow into oceans. Plants in freshwater ecosystems provide oxygen through photosynthesis and food for animals. Many animals live in freshwater ecosystems, with some adapted to fast moving waters and others to still waters. People rely on freshwater ecosystems for drinking water, energy, transportation, recreation and jobs like fishing.
Protecting aquatic ecosystems
The document discusses aquatic ecosystems and ways to protect them. It notes that aquatic ecosystems perform important functions like water purification but are threatened by human activity, wildlife overpopulation, and climate change. Some ways to protect aquatic ecosystems mentioned include reducing nutrient runoff, preventing pollution, restoring natural processes in lakes, and educating people. Conservation groups can also help protect lakes and ensure ecosystems of high value are preserved.
Biodiversity I
Coral reefs are extremely important ecosystems that provide habitat for 25% of marine life despite covering less than 1% of the ocean. They act as biodiversity hotspots and supply genetic diversity to other ocean regions via currents. The Coral Triangle in particular has the highest concentration of marine biodiversity and its protection is critical. Coral reefs are formed of calcium skeletons secreted by polyp organisms and provide food and shoreline protection to coastal communities while also contributing to carbon and water quality regulation. However, they are at risk from pollution, climate change, and destructive fishing practices.

It is home to thousands of species and provides food and jobs to the local economy. However, the reef is threatened by pollution, coastal development, ship traffic, and climate change, which have already damaged and killed parts of the reef. The reef ecosystem is highly complex, with coral polyps, fish, sharks, rays, and other species interacting as producers, grazers, predators, and through symbiotic relationships.
Marine ecosystem
Marine ecosystems cover over 70% of the Earth's surface and are home to a diverse range of organisms. They include nearshore habitats like salt marshes and coral reefs as well as open ocean areas. Marine animals include whales, dolphins, seals, octopuses, starfish, and many others. The marine food web begins with phytoplankton and algae which are eaten by herbivores and then carnivores, with top predators at the apex. Humans impact marine ecosystems through fishing, pollution, and climate change. International efforts aim to conserve and sustainably use ocean resources.

Aboriginal farming eels with rocks presentation
In southwestern Victoria, there were many small rivers and marshes that would flood in winter. These marshes were an important feeding ground for eels. In spring, eels would swim up the rivers from the sea to reach the marshes. The indigenous people had developed a well-planned system of traps and canals to farm eels as they migrated between the sea and inland waters. They would trap eels in nets and pots placed in the canals. Some of these canal systems covered over 100 square kilometers. The indigenous people would breed trapped eels, smoke them, and trade this important food source. Eel farming had been practiced in the region for around 8,000 years by these settled indigenous groups.

Ticks
Ticks go through different life stages and pose the greatest disease risk when largest as adult ticks. They typically find hosts like deer, hedgehogs, and sheep, and have about three blood meals before dying - with males dying after three meals and females using three meals as energy to lay eggs before dying.
Life cycle of a ladybug diyara kumarage
Ladybugs go through four life stages: eggs are laid on leaves and hatch into larvae, larvae eat pests like mites and aphids as they grow over 2-4 weeks while shedding their skin, then they form a pupa attached to a leaf for 5-7 days before emerging as soft pale adult ladybugs that soon harden their shell and brighten to the iconic red color.
Slug presentation final
Slugs play an important role in ecosystems by eating decaying plant material. They have two pairs of tentacles on their head for seeing and smelling, and breathe through a hole in their middle. Slugs move using mucus and muscle contraction from their foot, leaving behind a slime trail. They can lay 20-100 eggs several times a year in holes or under objects. Slug eggs can lay dormant for years before hatching when conditions are right, from 10 days up to 100 days depending on temperature. Newly hatched slugs immediately begin crawling and feeding at night if humidity and temperature allow.
Insect challenge
Students are tasked with designing the most perfect insect by combining beneficial features of real insects. Their insect must have a head, body, and legs, and may also include a tail, wings, antennae, or stinger.

Kl schoolsinthe past
Schools in the past used different tools and methods for teaching children compared to modern schools. Children sat in rows at wooden desks and were taught using slates, copy books, and abacuses. Teachers maintained discipline by using punishments like making children wear dunce hats or striking their hands with canes for misbehaving. At the end of each school day, teachers documented lessons and events in logbooks.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Coral reefs
- 1. CORAL REEFS
- 2. WHAT IS IT? An under water ecosystem which is made up of many plants and animals. You can find them in warm, tropical oceans close to the Equator.
- 3. How is it used? Humans use coral reefs to go: Snorkelling Cruising on boats Swimming And they also provide food and medicine. The Earth needs coral reefs for: A habitat for many different species A barrier to the coastline as protection from waves
- 4. What lives there? Did you know that coral reefs are home to about 25% of all ocean life in the world! There are many different animals such as: starfish coral polyps (which make the coral) jellyfish sea turtles sea anemones and many more!
- 5. What lives there? Plants that live in coral reefs include: Seagrasses Phytoplankton Algae Seaweed
- 6. How do coral reefs interact with water? The coral reef acts as a barrier to waves crashing into land. If the water is polluted from humans the health of the reef will suffer and the organisms will struggle. Coral reefs need water that is between 20 - 28°C.
