The presentation is aimed for undergraduate students and covers the details of forest ecosystem, grassland ecosystem, desert ecosystem as well as aquatic ecosystems. It is suitable for compulsory environmental science course at undergraduate level. The content has been simplified for easy understanding of both science as well as humanities students.
A food web is a more complex network, graphical model depicting the many food chains linked together to show the feeding relationships of organisms in an ecosystem.
Food web is an important ecological concept. Basically, food web represents feeding relationships within a community (Smith and Smith 2009)

MAJOR TYPES OF ECOSYSTEMS
1. TERRESTRIAL ECOSYSTEMS
2. AQUATIC ECOSYSTEMS
Terrestrial ecosystems
A terrestrial ecosystem is an ecosystem found only on landforms.
Six primary terrestrial ecosystems exist:
tundra,
taiga,
temperate deciduous forest,
tropical rain forest,
grassland; and
desert.
Ecology derived from two Greek word “oikos” means house, habitation or place of living & “logos” means study.
Definition: Ecology is the study of interrelationship between living organism and their physical and biological environment.
The biotic elements that comprise an ecosystem fall into one of several trophic levels. The trophic level of an organism is its position in a food chain, the sequence of consumption and energy transfer through the environment.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Normal Labour/ Stages of Labour/ Mechanism of LabourWasim Ak
Normal labor is also termed spontaneous labor, defined as the natural physiological process through which the fetus, placenta, and membranes are expelled from the uterus through the birth canal at term (37 to 42 weeks
4. Producers
A. Sunlight is the main energy source for life on
earth
B.Also called autotrophs
C. Use light or chemical
energy to make food
1. Plants
2. plant-like protists (algae)
3. Bacteria
5. D. Photosynthesis—use light energy to convert carbon
dioxide and water into oxygen and carbohydrates
(Remember: 6CO2 + 6H2O
Light Energy
6O2 + C6H12O6)
E. Chemosynthesis—performed by bacteria, use chemical
energy to produce carbohydrates
9. Feeding Interactions
A. Energy flows through an ecosystem in one direction—
from the sun or inorganic compounds to autotrophs
(producers) and then to heterotrophs (consumers)
10. B. Food Chain—series of steps in which organisms transfer
energy by eating and being eaten
1. Arrows go in the direction of how energy is
transferred
2. Start with producer and end with top consumer
or carnivore
Ex: grass
cricket
frog
raccoon
11. C. Food Web—network of food chains within an ecosystem
Hawks
Weasels
Raccoons
Mice
Grass
Which of the organisms above is the producer?
Which of the organisms above is the top consumer?
12. D. Trophic Levels—each step in a food chain or food web
1. Level 1—Producers (autotrophs)
2. Level 2—Primary Consumers (herbivores)
3. Level 3—Secondary Consumers
(carnivores or omnivores)
4. Level 4—Tertiary Consumers
(carnivore—usually top carnivore)
14. IV. Ecological Pyramids
A. Diagram that shows the relative amount of energy or
organisms contained within each trophic level of a
food
chain or web
15. B. Energy Pyramid shows relative amount of energy available at
each trophic level
1. Organisms in a trophic level use the available
energy for life processes (such as growth,
photosynthesis, cellular respiration, metabolism,
etc.)and release some energy as heat
Remember: Every chemical process that happens in your
body releases heat as a byproduct (ex: burning calories).
2. Rule of 10—only about 10% of the available energy
within a trophic level is transferred to the next
higher trophic level
C. Biomass Pyramid—represents the amount of living
matter at each trophic level
organic
17. Energy and Biomass Pyramid (together)
Represents amount of energy
available at each level as well
as amount of living tissue—
both decrease with each
increasing trophic level
18. V. Ecological Interactions between organisms
A.Competition—when two organisms of the same or
different species attempt to use an ecological resource in
the same place at the same time.
Ex: food, water, shelter
20. Until Americans introduced gray squirrels into parts of
England in the early 20th century, red squirrels had been
the only species of squirrel in the country. The gray
squirrels were larger and bred faster and successfully
competed for resources. Within a couple years of overlap
in an area, the red squirrels disappeared.
21. B. Niche—the ecological niche involves both the
place where an organism lives and
the roles that an organism has in its habitat.
Example: The ecological niche of a sunflower growing in the
backyard includes absorbing light, water and nutrients
(for photosynthesis), providing shelter and food for
other organisms (e.g. bees, ants, etc.), and giving off
oxygen into the atmosphere.
22. The ecological niche of an organism depends not only on
where it lives but also on what it does. By analogy, it may
be said that the habitat is the organism’s “address”, and
the niche is its “profession”, biologically speaking.
Worm’s Niche
“Address”—Soil, Ground, etc.
“Profession”– Mix-up soil
23. C. Predation—one organism captures and feeds on
another organism
1. Predator—one that does the killing
2. Prey—one that is the food
24.
25. D. Symbiosis—any relationship in which two
species live closely together
1. Mutualism—both species benefit (WIN-WIN)
a. Ex: insects and flowers
Can you think of any other examples that we’ve talked about in class?
26. 2. Commensalism—one member of the association
benefits and the other is
neither helped nor harmed.
(WIN-0)
Example: barnacles on a whale
27. The Remora fish attaches to
the shark and gets a free ride.
Commensalism
Birds build nests in trees.
28. 3. Parasitism—one organisms lives on or inside
another organism (host) and harms it.
The parasite obtains all or part of its nutritional
needs from the host. (WIN-LOSE)
Example: fleas on a dog
29. Wasp eggs on back of
caterpillar.
Parasitism
Sea lampreys feed on
fluids of other fish.
Mosquito biting a
human.
