Coral reefs are complex ecosystems that are home to vast biodiversity. Reef inhabitants like fish have adapted traits such as flattened bodies and colorful patterns to survive in the reef environment. The coral reef trophic system consists of four levels - primary producers like algae, primary consumers like corals, secondary consumers like butterflyfish, and apex predators like barracuda. Carbon and nitrogen cycles also occur as materials are exchanged between organisms and their environment. There are different types of ecology that study reefs, including organismal, population, community, ecosystem, and global ecology.

It takes 3-4 years for a clam to mature to market size.
Some clams can produce pearls.One in 5,000 clams forms a pearl.
A clam can live until about 35 years if not eaten.
distribution:
Marine clams are abundant in the low and mid intertidal zone in temperate seas globally. Other species of marine mussel live in tropical intertidal areas, but not in the same huge numbers as in temperate zones.
Certain species of marine clams prefer salt marshes or quiet bays, while others thrive in pounding surf, completely covering wave-washed rocks. Some species have colonized abyssal depths near hydrothermal vents. The South African white mussel exceptionally doesn't bind itself to rocks but burrows into sandy beaches extending two tubes above the sand surface for ingestion of food and water and exhausting wastes.
Freshwater clams inhabit permanent lakes, rivers, canals and streams throughout the world except in the polar regions. They require a constant source of cool, clean water. They prefer water with a substantial mineral content, using calcium carbonate to build their shells.
In aquatic animals such as fish respiration takes place through special respiratory organs called gills, however lung fish respiration takes place through lungs. Gills are present on both the sides of the head of fish. The gills are covered by gill covers also called operculum. When the fish open its mouth, water is drawn into the buccal cavity and passed through the gills. The gills contain special type of cells that absorb the oxygen present in water. The absorbed oxygen is then supplied to all the cells of body through blood. In the cells, oxygen is converted into carbon dioxide and returned back to gills through blood. Ultimately, the gills release the carbon dioxide in water passing through them.
Respiration in Fish
The gills of fish are very efficient; it is estimated gills can extract about 80% oxygen dissolved in water. In addition to the respiratory organs, the gills have an important role in maintaining the right balance of salts in the body.

Introduction
Marine oil spills can affect the ecosystem both through their physical influence on the organisms and through the effect of the various chemicals in the oil. On the physical side, organisms can get caught in the viscous oil. Oil can also form a barrier to the surface, which can be damaging for some species of fish when they come to the surface to fill the swim bladder (Sundby et al., 2013). There are also several chemicals in the oil that can increase the mortality for eggs and larvae (Neff et al., 2000; Barron et al., 2004). Oil can stimulate the formation of marine snow (Passow et al., 2012) that may subsequently sinks to the ocean floor where it can impact the benthic fauna. If conditions become anoxic, oil in the sediment would decay more slowly since the biological remineralization of the oil is retarded in anoxic conditions. The use of dispersants to increase the rate of remineralization has also received attention in terms of its potential negative effect on the ecosystem (Kleindienst et al., 2015; Vikebø et al., 2015).
This study focuses on the seas around southern Norway (Figure 1), where the currents are dominated by the Norwegian Coastal Current (NCC) that flows along the coast all the way from the Skagerrak to northern Norway. This current would primarily transport oil spills, eggs, and larvae along the coast. In the northern part of the area, the NCC flows side by side with the Norwegian Atlantic Current (NAC), which is a more saline current also directed northwards. Strong winds of variable directions and high waves occur frequently, particularly during winter, and contribute to the upper layer drift. The area has strong mesoscale activity, particularly in the frontal region between the fresher NCC and the eastern branch of the NAC, and thus it is difficult to predict the local currents on short time scales. The tidal amplitudes, and consequently the tidal currents, are small (<1.0 m) in the southern parts of Norway, but become larger in northern Norway.

Whiteleg shrimp (Litopenaeus vannamei, formerly Penaeus vannamei), also known as Pacific white shrimp or King prawn, is a variety of prawn of the eastern Pacific Ocean commonly caught or farmed for food.L. vannamei is a decapod crustacean which is native to the Eastern Pacific Coast of Central and
South America from Tumbes, Peru in the south to Mexico in the north. It has been introduced widely around the world since the 1970s, but especially since 2000, as it has become the principle
cultured shrimp species in Asia. The species itself is not considered a major threat to biodiversity, does not appear to have formed breeding populations, and has generally resulted in positive economic impacts in non-indigenous areas. An examination of current lists of invasive species
published by the International Union for Conservation of Nature’s Invasive Species Specialist Group (IUCN, 2004) revealed no listings for L. vannamei. As mentioned, L. vannamei has been anthropogenically introduced as an aquaculture species to several areas of the world to which it is

ADAPTATION OF MARINE ORGANISMS TO DIFFERENT ENVIRONMENTJaneAlamAdnan
Adaptation is an evolutionary process whereby an organism becomes increasingly well suited to living in a particular habitat. It is not a quick process! Natural selection over many generations results in helpful traits becoming more common in a population. This occurs because individuals with these traits are better adapted to the environment and therefore more likely to survive and breed. Adaptation is also a common term to describe these helpful or adaptive traits. In other words, an adaptation is a feature of an organism that enables it to live in a particular habitat.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

3. CORAL REEF ECOLOGY
Coral reefs are often referred as one of the most marvellous creations of nature. It is also
one of the oldest types of ecosystems with a huge variety of living things and non living
things. Although coral reefs account for about around one percent only of the ocean floor, it
is home to at least twenty five percent of the whole marine life. Most reefs are normally
located in clear tropic oceans with a depth not exceeding forty five metres as corals depend
on sunlight for their survival. The largest reef known to man is 'the great barrier reef'
located off the coast of north east of Australia.
Corals are in reality clusters of thousands of tiny animals called "coral polyps" and not rocks
or plants as it is believed generally. These tiny organisms produces calcium carbonate to
form a protective layer around them. This layer is the first step in reef building, later on
these fragments of corals grow wider and merge to form a fringing reef which is followed by
a barrier reef and the last stage is an atoll as shown in the picture below.
the firststage is a fringingbarrieraroundthe island.

4. ADAPTATION TO REEF
Coral reefs are complex and densely populated ecosystemwith a huge biodiversty. Among the
inhabitants, the various types of fish stand out as they are not like normal ocean dwellers.
This is due to the adaptation they had to undergo so as to be able to live easily in the reefs.
One such adaptation is their flat body, this is so because the reef fish has to operate in
rather confined spaces, between narrow canals or through the complex structure of the
reef. Another reason why they have a flattened shape is for a better manoeuvrability and also
the ability to dart or change directions swiftly, most of the time this is performed to escape from
predators by hiding around the corals or dodge their attacks. Many reef fish, such as the
butterflyfish andangelfish,have evolvedbodieswhichare flat.Theirfinsare alsodesignedaccording
the thin body to maximise manoeuvrability.
the figure above shows us the difference stated between an angelfish, a reef fish and a
bluefin tuna, an open sea fish.
Reef fishes have another unique feature and it is their live and colourful stripes or patterns
unlike open water fishes with silver shades. The patterns and the lively colours also have
their use apart from making the reef habitants beautiful. This is used by the small fishes as a
means of defence to warn their predators that they are poisonous or contain toxic spines
some examples are: clownfish, angelfish and the royal gramma. In some cases the
coloration of the animal can provide a good camouflage provided that it is in the right
background for example, a lionfish resting among the corals.
AN EXAMPLE OF CAMOUFLAGE OF A
REEF FISH
5. Camouflage as stated above is used by fish who are down the food chain. With time, even
the predatory fish have adopted this technique of blending into the nature to catch their
food. they are called 'ambush predators' as they stay still and suddenly they attack their
prey. Some types of ambush predators are namely: frogfish, scorpionfish and the grouper.
Another adaptation the reef dwellers had to adopt new ways of feeding themselves. Some
species of marine animal makes use of the coral reef as a trap for others such as the giant
moray eel who is seen in cooperative hunting with loepard groupers.
TROPHIC LEVELS
In a coral reef, there is more than one food chain for most organisms as they eat more than
one kind of food or are eaten by more than one type of predator. A food web is then
established with the given data with the aim to distinguish the levels of the myriad species
living in the reef. The trophic level is usually classified by four levels which are:
level 1-primary producers(plants)
examples would be :zooxanthellae and phytoplankton who produces their own food
through photosynthesis.
level 2-primary consumers(herbivores)
examples would be :corals and small inverebrates which feeds on zooxanthellae only
The grouperusingcamouflage to
catch his food.
6. level 3-secondary consumers(carnivores)
examples would be :butterfly fish which feeds on coral polyps and damselfish which feeds
on algae and other plants.
level 4-tertiary consumers(apex predators)
examples would be :barracuda and reef shark who in turn feeds on butterfly fish and other
coral dweller smaller than them.
Biomass transfer efficiency
The diagram above shows us the energy pyramid with respect to the food chain. The ones at
the bottom hold more energy than those at the peak. This is because as the trophic levels
are ascended the energy is divided by a factor of 10.
e.g: a plant processes 1% of chemical energy, this is then processed by a herbivore fish
whose energy output would be 0.1% followed by the carnivore's fish energy at 0.01% and
finally the apex predator obtains only 0.001% of the initial energy processed.
Biochemical cycles in coral reefs
1 carbon cycle
Sources of carbon cycle is as follows:
cellular respiration-is a metabolic process where organisms releases energy.Carbon
dioxide is produced and circulated into the body
plants such as algae and mangroves uses carbon for photosynthesis
external skeleton of corals composed of calcium carbonate (a compound of carbon)
7. 2 nitrogen cycle
sources of nitrogen cycle is as follows:
1. nitrogen is trapped in soil.
2. plants take up nitrogen from soil.
3. fish eats plant and retains the nitrogen.
4. carnivore fish eats initial fish.
5. secondary consumer dies and decomposer starts breaking the body.
6. nitrogen is released back in the ecosystem.
Types of ecology
1 Organismal ecology focuses mainly on the adherence of the organism to it environment in
morphological, physiological and behavioral ways.
2 Population ecology concerns only one specie and sees how it interacts with its
surroundings.
3 Community ecology is the interactions between groups of species in an area.
4 Ecosystem ecology is the study of how biotic and abiotic components interact within an
ecosystem framework.
5 Global ecology is the study of all types of ecology in a world scale where all ecosystems
interacts with each other.
