Ecology is the scientific study of interactions between organisms and their environment. There are biotic (living) and abiotic (non-living) factors that influence ecosystems. Producers, like plants, use photosynthesis or chemosynthesis to produce food from sunlight or chemical energy. Consumers rely on producers or other organisms for food and include herbivores, carnivores, and omnivores. Energy and nutrients transfer between trophic levels in a food chain or food web. Ecological pyramids show that the amount of available energy and biomass decreases at higher trophic levels due to only about 10% of energy transferring between levels. Organisms also interact through competition for resources, ecological niches,

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.
This Presentation is about the various types of ecosystem which is present in our environment.....It is also for students who are interested in this topic
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.

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.

"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.
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.
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 6O2 + C6H12O6)
E. Chemosynthesis—performed by bacteria, use chemical
energy to produce carbohydrates
Light Energy
6. Consumers
A. Organisms that rely on other organisms
for their energy and food supply
B. Also called heterotrophs
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
Which of the organisms above is the producer?
Which of the organisms above is the top consumer?
Hawks
Weasels Raccoons
Mice
Grass
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 organic
matter at each trophic level
17. Represents amount of energy
available at each level as well
as amount of living tissue—
both decrease with each
increasing trophic level
Energy and Biomass Pyramid (together)
19. 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
21. 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.
22. 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.
23. 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
24. C. Predation—one organism captures and feeds on
another organism
1. Predator—one that does the killing
2. Prey—one that is the food
25.
26. 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?
27. 2. Commensalism—one member of the association
benefits and the other is
neither helped nor harmed.
(WIN-0)
Example: barnacles on a whale
29. 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
30. Parasitism
Wasp eggs on back of
caterpillar.
Mosquito biting a
human.
Sea lampreys feed on
fluids of other fish.
