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.
It is quite interesting to note that the only producer of food in the entire world is PLANT. All others are consumers, and depend only on plants to provide food to all the living organisms and species.
In this episode, we are going to learn the following aspects:
1. Definition of an Ecosystem
2. Biotic Components
3. Abiotic Components
4. Functions of an ecosystem
5. Processes of ecosystems.

This presentation gives an idea about our ecosystem, our environment, it's various components, the flora and fauna and others elements related to it. It also explains about how our environment functions.

1. What roles does succession and phytoremediation play in ecology, .pdfarakalamkah11
1. What roles does succession and phytoremediation play in ecology, evolution and the
ecosystems?
Succession plays a major role to change in environmental conditions that causes a pronounced
change in an ecosystem. Disturbances often act quickly and with great effect, to alter the
physical structure or arrangement of biotic and abiotic elements. Disturbance can also occur over
a long period of time and can impact the diversity within an ecosystem. Major ecological
disturbances may
include fires, flooding, windstorms, insect outbreaks and trampling. Earthquakes, various types
of volcanic eruptions, tsunami, firestorms, impact events, climate change, and the devastating
effects of human impact on the environment (anthropogenic disturbances) such as clear cutting,
forest clearing and the introduction of invasive species can be considered major disturbances.
This can be attributed to physical changes in the biotic and abiotic conditions of an ecosystem.
Because of this, a disturbance force can change an ecosystem for significantly longer than the
period over which the immediate effects persist. With the passage of time following a
disturbance, shifts in dominance, shifts in dominance may occur with ephemeral herbaceous life-
forms progressively becoming over topped by taller perennials herbs, shrubs and trees. However,
in the absence of further disturbance forces, many ecosystems will trend back toward pre-
disturbance conditions. Long lived species and those which can regenerate in the presence of
their own adults will finally become dominant. Such alteration, accompanied by changes in the
abundance of different species over time, is called ecological succession. Succession often leads
to conditions that will once again predispose an ecosystem to disturbance.
Phytoremediation play a major role to clean up contaminated environments including metals,
pesticides, explosives, and oil. Also help prevent wind, rain, and groundwater flow from carrying
contaminants away from the site to surrounding areas or deeper underground. Certain plants are
able to remove or break down harmful chemicals from the ground when their roots take in water
and nutrients from the contaminated soil, sediment, or groundwater. Plants can help clean up
contaminants as deep as their roots can reach using natural processes to:
• Store the contaminants in the roots, stems, or leaves.
• Convert them to less harmful chemicals within the plant or, more commonly, the root zone. •
Convert them to vapors, which are released into the air.
• Sorb (stick) contaminants onto their roots where very small organisms called “microbes” (such
as bacteria) that live in the soil break down the sorbed contaminants to less harmful chemicals.
2. Biogeochemical cycles, succession and phytoremediation. Explain how all three work together
for a positive outcome.
Biological diversity is dependent on natural disturbance. The success of a wide range of species
from all taxonomic groups is closely tied to na.
Nutrient cycling is one of the most important processes that occur in an ecosystem. The nutrient cycle describes the use, movement, and recycling of nutrients in the environment.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

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.
