Ecology is the study of living organisms and their interactions with each other and their environments. It has many branches that study specific areas like behavior, physiology, evolution, ecosystems, populations, communities, and landscapes. Key branches also include conservation biology, restoration ecology, ecotoxicology, and molecular ecology. Solving ecological problems requires considering biotic factors like competition, quantitative factors like population sizes, climatic factors like temperature and chemistry, taxonomy, and genetic/evolutionary aspects. Ecology blends aspects of other biological sciences to study the complex relationships between organisms and their environments.
Ecological Succession is the process of change in the species structure of an ecological community over a period of time.
But, over a long period of time, the climate conditions of an ecosystem is bound to change.
No ecosystem has existed or will remain unchanged over a Geological Time Scale.
Energy Flow in Environment : Ecological EnergeticsKamlesh Patel
What is Energy:
The ability or capacity to do work,
Radiant, Chemical, thermal, mechanical, nuclear, electrical.
What is Energy Flow:
The existence of flora and fauna in ecosystem depends upon the cycle of minerals and flow of energy. Energy is needed for all the biotic activities. The only source of this energy is the sun. The entrance, transformation and diffusion of energy in ecosystem are governed by laws of thermodynamics.

Marine ecology deals with the study of the environment and life in marine waters. It involves the study of marine organisms and their habitat. The details of marine ecosystems are given in this module.
Ecology is the scientific study of organisms `at home' which is called as the `environment'. The term `environment' refers to those parts of the world or the total set of circumstances which surround an organism or a group of organisms.
Points on biomes,habitat,ecotone and their differentations.
also on terrestrial ,wetland,fresh water,marine habitat and their types .Explained much with pictures..so easy to remember and to take class .Hope this may help....
Community ecology, study of the organization and functioning of communities, which are assemblages of interacting populations of the species living within a particular area or habitat.
This is the introductory lesson of the course; 'Foundation of Environmental Management' taught at the Faculty of Social Sciences and Humanities of the Rajarata University of Sri Lanka

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.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

2. Ecology
• Ecology is a Greek word which means the
study of the habitation of living organisms
(oikos=habitation, logos=discourse).
• Some define it as
– “scientific natural history” or
– “the science of community population” or
– “the study of biotic communities”.
3. Definition
• A study of animals and plants in their relation
to each other and to their environment.
• Ecology - Ernst Haeckel (1869)
4. Branch of Biology
• Ecology till recently was considered in
academic circles to be a, which, along with
molecular biology, genetics, developmental
biology, evolution etc. was by no means
always considered as one of the subjects of
biological sciences only.
5. Study of Ecology
• Study of plant ecology or animal ecology.
• Bio-ecology.
• The term Synecology denotes ecological
studies at the community level while the term
Autecology denotes ecological studies at the
species level
6. History of Ecology:
• In a sense ecology is the new name of ‘Natural
history’.
• In France and Spain --- cave-dwellers about the
fauna and flora around them.
• ‘The Histories of Animals’ of Aristotle (384-322
B.C.) is a famous contribution in this line.
• The first naturalist to give a systemised
knowledge about the relation existing between
living organisms and environment was Buffon.
In a series of work in 1749, he stressed on habits
and adaptations.
7. Branches of Ecology
• Ecological studies focus on how various
organisms interact with their environment.
There are a number of fields within ecology,
either focusing on specific areas of interest or
using particular approaches to address eco-
logical problems.
8. The sub-fields or branches of ecology
i. Behavioural Ecology:
• It is concerned with explaining the patterns of
behaviour in animals.
ii. Physiological Ecology or Eco-Physiology:
• It deals with how organisms are adapted to respond to
temperature, maintain proper water and salt balance,
balance levels of oxygen and carbon dioxide, or deals
with other factors of their physical environment.
9. iii. Molecular Ecology:
• Directly tackle ecological problems is the focus of
molecular biology.
iv. Evolutionary Ecology:
• evolution on current patterns and human induced
changes. It relates to
• how animals choose mates, determine the sex of their off-
spring, forage for food and live in groups, or
• how plants attract pollinators, disperse seeds, or allocate
resources between growth and reproduction.
10. v. Ecosystem Ecology:
• The interaction between the biotic and abiotic
components called an ecosystem is the sub-field of
ecology called ecosystem ecology.
vi. Population Ecology:
• Population ecology constitutes organisms of the
same species living in the same place and same
time. It may comprise of the dynamics of a single
population of any living thing (earthworm, fox,
whale, pine tree etc.) or may focus on how two
populations (predator and its prey or parasite and
its host) interact with each other.
11. vii. Community Ecology:
• Populations of many different organisms in a
particular place are tied to one another by feeding
relationships and other interactions. These
relationships of interacting populations are called
ecological communities and their study is under the
purview of community ecology.
viii. Landscape Ecology:
• These are of ecological fields whose study requires
the synthesis of several other sub-fields of ecology.
Landscape ecology is one that emphasizes the inter-
connections among ecosystems of a region.
12. • The values of landscape ecology are:
• (a) It emphasises on larger land areas of interacting
ecosystems, i.e., next higher level of organisation
above the local ecosystem, and
• (b) Its tendency to compartmentalize. We study a
lake or forest ecosystem but landscape ecology
considers the connections between them. For
example, herons forage in the lake, nest in the
forest and, thus, the herons move nutrients from
water to land.
13. ix. Conservation Biology:
• This sub- field of ecology blends the concepts of
genetics with population and community ecology. It
takes a landscape approach and is related to the
maintenance of biodiversity and the preservation of
endangered species.
x. Restoration Ecology:
• It relates to the re-establishing of the integrity of
natural systems that have been damaged by human
activity.
14. xi. Ecotoxicology:
• It is the study of the fate and action of human-
made substances, such as pesticides and detergents,
in the natural world.
• Ecotoxicology focuses on the way in which human-
made substances affect human health.
• Eco-toxicologists often use other animals, such as
fish or small invertebrates, as models for the action
of the particular toxic substance under study.
15. Scope of Ecology:
• The solution of a particular ecological
problem requires several lines of approach.
None of this constitute an end in itself but
each one of these makes important
contribution in making the picture complete.
16. Ecological Problem
(a) Biotic
(b) Quantitative
(c) Climatic (both physical and chemical)
(d) Taxonomic
(e) Genetic and evolutionary.
17. Biotic factors
• Biotic factors are the direct outcome of the
various types of activities amongst the
animals. A competition for food and shelter
always exists amongst the members of a
community. This competition demands
various types of activity amongst the animals.
18. Quantitative study
• Quantitative study includes an assessment of
the population density in a given area and
also an estimation of the number of members
present in different communities. Information
of this kind is of immense value in solving
many problems like food availability and
movement within a particular colony.
19. Climatic factors
• Climatic factors include both physical and chemical
conditions present in a habitat. These factors are
ever changing in nature.
• Physical factors include mainly temperature, light
and humidity.
• Chemical factors include acidity or salinity that are
specially present in aquatic habitat.
• Some animals are so sensitive that a minute climatic
change becomes fatal to them. Climatic factors play
an important role in the distribution of animals.
20. Taxonomy
• Taxonomy means classification, naming and
description of organisms. A mere naming of a
large number of animals of a given area, as
was done earlier in ecological surveys, is
meaningless without a consideration of the
circumstances that enable them to live there.
Thus a complementary observation of the
various ecological factors together with
taxonomy is emphasized in ecology.
21. Genetic And Evolution
• The genetic and evolutionary aspects have
taken a rightful place in ecological problems.
In recent years the knowledge of heredity and
the mechanism of the operation of Natural
Selection have increased to a considerable
extent.
