1. The document discusses food chains and food webs in marine and freshwater ecology. It explains the trophic levels and differences between food chains and complex food webs.
2. It also compares freshwater and marine fish, noting differences in their habitat, species, and physiology. Freshwater fish live in environments with less salinity while marine fish require saltwater.
3. Additionally, the document talks about Saudi Aramco's efforts to promote biodiversity through artificial reefs deployed in the Arabian Gulf and Red Sea. Over 3,000 reef blocks have increased species numbers and productivity at sites like Manifa and Jubail.
A Powerpoint on teaching Aquatic Ecology
I found this by doing a "Google Search" on
"Aquatic Ecology" and ".ppt"
I posted this here for the benefit of a young teacher friend, but also wanted to make the point, especially to users of eInstruction's classroom Performance System, that by doing such a search, they can easily find Powerpoints they can use with their CPS system.
Also , Powerpoint will let you "save as " .jpg
so you can also use individual slides as graphics to illustrate individual CPS questions.

Freshwater Ecosystems include standing water or lentic such as lakes, ponds, marshes and wet lands, and the flowing water or lotic such as spring, streams and rivers. This ecosystem is normally of very low salinity usually between 15 to 30 ppt. They are highly variable and their characteristics depend upon the surrounding geology, land use and pollution levels.
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes and ponds, rivers, streams and springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. This module explains the characteristics of aquatic ecosystems-freshwater ones.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
"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.
WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.
Marine and freshwater ecology understanding the complexities of food chains and food webs
1. Marine and freshwater Ecology:
Understanding the Complexities of
Food chains and food Webs
Prepared By: Amani Alsharidah
University Number: 441203711
1443-2021
3. Introduction
• Organisms interact with their community and
environment.
• And because the large number of species life in
the same area or different area. We will have a lot
of interaction between them.
• Our Knowledge of these interaction is limited.
5. • Food chain is the series of organisms of an ecosystem which
the food and energy present in it and passes with each member.
• A food chain consists of three Trophic Levels.
Food chain
6. Food chain divide to:
In this chain, energy and nutrients
move from plants to the herbivores
then to carnivores or omnivores.
1.The grazing food chain
2. Detrital food chain
• In this chain, its starts with dead
organic matter which is eaten by
animals then to other animals...
• A large amount of energy flows
through this chain.
7. Difference between grazing and detritus food chain
Helps in fixing inorganic nutrients
Take up energy from the detritus,
ensuring maximum utilization and
minimum wastage
Detritivores (decomposers)
Detritus
Fixes inorganic nutrients
Adds energy into the ecosystem
Sun
Green Plant ( producer)
Grazing
Remains of detritus
Begin with
Energy Source
Importance
8. Trophic Levels
Organisms in food chains are grouped into categories
called trophic levels.
First trophic level
1. Producers
Second, third, and
fourth trophic levels
2. Consumers
3. Decomposers
9.
10. 1. Producers (Autotrophs)
• They are the first level of every food chain.
• Autotrophs are usually plants or one-celled
organisms.
• Nearly all autotrophs use a process called
photosynthesis to create Glucose from
sunlight, carbon dioxide, and water.
11. Type of Producers
Most familiar Type
Plants
Tiny organism
Phytoplankton
Larger form of its called
seaweed
Algae
Some type of it.
Bacteria
13. Consumer
Turtles, Crustaceans,
Sea snails, and many
types of Fishes
Top predators, also
called apex predators,
eat other consumers.
Eat the herbivores
Eat the secondary consumers.
There may be more levels of
consumers before a chain
finally reaches its top predator.
Primary
herbivores
Tertiary
Secondary
Top
14. Depend on what the
consumers eat it can be: Animals eat only
Carnivores
Omnivores
Eat both plants and animals
15. 3. Decomposers
Detritivores and decomposers are the final part of
food chains
Detritivores are organisms that eat non-living plant
and animal remains.
16. The important of decomposers
They turn organic wastes into inorganic materials.
Decomposers complete the cycle of life, returning
nutrients to the soil or oceans for use by autotrophs.
Decomposers like fungi and bacteria complete the
food chain.
This starts a whole new food chain.
17. Aquatic food chain
Producers
1. Phytoplankton
Primary Consumers
Provide food for small fish
2. Zooplankton
3. Small fish
Secondary Consumers
Provide food for large fish
4. Large fish
Tertiary consumers an
animal on the third
trophic level
18. • It is an important ecological concept consist of a number
of food chains meshed together.
• Food web offers an important tool for investigating the
ecological interactions that define energy flows and
predator-prey relationship
Food web
19. Importance of the study of food webs
● Show us how energy flows through an ecosystem.
● Understand how toxins and pollutants become concentrated
within a particular ecosystem. (bioaccumulation)
● Study and explain how the diversity of species is related to
how they fit within the overall food dynamic.
● They may also reveal critical information about the
relationships between invasive species and those native to
a particular ecosystem.
20. Trophic Levels in a Food Web
The Same as the food chain
Who Can talk about it
?
21.
22. • Energy enters a community when plants
and algae trap light energy during
photosynthesis.
• They change the light energy into chemical
energy in glucose, which then moves
through the community as different
organisms eat each other.
• Some energy is stored through fossilisation,
while most of it is lost through heat
dissipating into the environment.
Energy Flow
24. Types of food webs
1. Energy Flow
2.Fossil
3. Functional
25. It is depict the
relationships between organisms in
an ecosystem by quantifying and
showing the energy flow between
organisms.
1. Energy flow food webs
26. In a fossil food web, scientists attempt
to reconstruct the relationships
between species based on available
evidence from the fossil record.
2. Fossil Food Webs
27. It depict the
relationships between organisms in
an ecosystem by depicting how
different populations influence the
growth rate of other populations
within the environment.
3. Functional Food Webs
28. Freshwater & Marine Ecosystem
• Its cover more than three-quarters of the
Earth’s Surface.
• Its providing an array of critical
ecosystem services, from participating in
various biogeochemical cycles and
nutrient exchange, to providing natural
protection and habitat, to degrading and
dispersing many environmental
pollutants.
29. The main difference between freshwater and marine
water fish
1.Habitat
2. Species
3. Physiology
30. • Freshwater fish live in
streams, rivers and lakes.
• They can adapt to a change in
habitat, like the rise and fall in
water levels, temperature and
oxygenation levels.
Freshwater Marine water
• Marine life refers to fish
living in oceans and seas.
• These are also known as
saltwater fish because they
can only stay alive in waters
with high salinity levels.
• A marine animal's habitats
include coral reef and
seagrass bed.
1. The habitat
31. • Freshwater fish can be cold
water or tropical.
• Cold water species include
trout and goldfish.
• Tropical freshwater species
are catfish and angelfish.
Freshwater Marine water
• Marine fish are all cold-water
fish.
• These include seahorses,
sharks, common dolphin and
tuna.
2. The Species
32. • Freshwater fish retain more
salt in their bodies than in the
water they live in.
• This is why they can survive in
waters with less than 0.05
percent salinity
Freshwater Marine water
• Saltwater fish lose water to
their surroundings through
the process of osmosis.
• They need to drink lots of
salty water to maintain a
healthy body.
3. The Physiology
33. Promoting Biodiversity
Artificial reefs Coral reefs are home to
invaluable ecological and
economic richness, nurturing
marine species and providing a
natural defense against coastal
erosion.
34. Reefs across the globe have been degraded
by natural and human pressures.
Those in the Arabian Gulf are no exception,
being at risk of disappearance from a
combination of climate change factors and
human activities such as fishing, dredging,
and marine pollution.
Promoting Biodiversity
Artificial reefs
In Saudi Arabia
35. Aramco has actively promoted the growth of
marine life in the Gulf with planned and
unplanned artificial reefs.
In total, 3,247 reef blocks have been
deployed at 25 sites in the Arabian Gulf,
alongside a reef structure in Jizan, Red Sea.
Deployment sites in the Arabian Gulf include
the region of Manifa, Abu Ali, Jubail, Ras
Tanura, Jana Island, Safaniya and Khafji.
Promoting Biodiversity
Artificial reefs
In Saudi Arabia
36. Seasonal monitoring of the artificial reefs
examined productivity, species biodiversity and
fish numbers.
The results indicated that the central part of the
Arabian Gulf, specifically the region of Manifa,
Abu Ali, Jubail and Ras Tanura was the area with
the highest abundance of reef fish, the highest
biodiversity of reef organisms, and the highest
biomass productivity
